Flex UI release notes for 2.x.x

@twilio/flex-ui@2.9.1

Release date November 6, 2024

• If an agent on a voice call clicked Hang up more than once, a "Could not wrap up reservation" error message appeared even though there was no actual problem. We've corrected this issue so the incorrect error message no longer appears.
• If an agent placed an outbound call and canceled it within 5 seconds, this error appeared: "WorkerActions.AcceptTask: no active call." We've corrected this issue so the incorrect error message no longer appears.
• In some scenarios, the following error message appeared in Twilio Console and Status Report (if enabled) even though the call behaved normally: "WorkerActions.AcceptTask: Could not accept call: 'Stuck task' scenario 1 flavour 1 intercepted: a call task is still pending after 5 seconds, but its voice call is up." This error message was inaccurate and no longer appears in scenarios without an actual problem.
• In Teams view, some tasks appeared to be stuck in Wrap up state even after the task had been completed. This issue has been fixed.
• In rare circumstances, when playing calls in Flex Insights, the Segments links to skip to specific conversation segments were unavailable beginning in Flex 2.x.x. The links now work as expected.
• When a page includes multiple timers that show how long a task has been in its current status, the timers can sometimes be up to 1 second apart from each other. This has been corrected, and you'll see that all timers show the same value.
• Fixed an issue where the Flex voice client answers calls intended for another voice client.

@twilio/flex-ui@2.9.0

Release date October 3, 2024

Flex UI 2.9.0 is now available. Beginning with this release, we have certified that Flex UI works on Chromebooks, expanding your device options. In Unified Profiles, your agents can now view customer interactions history information before any of your customer data sources are connected, immediately enabling them to provide more customized, efficient service. Throughout Flex UI, you'll find a broad range of feature and UI enhancements, bug fixes, and more.

• Flex UI is now certified to work on Chromebooks.
• In Unified Profiles, added the ability for your agents to begin viewing basic customer interaction history before any of your customer data sources are connected. This allows agents using Unified Profiles or Agent Copilot to quickly review customer interaction history before or during customer interactions to provide more customized, efficient service.

• In Unified Profiles:
  • In the Customer history UI component, you can now configure recent activity groups to show your agents the most recent customer activity within the last 24 hours and up to 14 days out.
  • Updated the UnifiedProfilesContainer that contains customer detail, history, and header UP components to always render the same view and the component itself to render any errors that occur. Previously, the container rendered different views within the tabs based on errors that occurred.
    • The UnifiedProfilesContainer is now programmable. You can remove, hide, show, rename, sequence, and customize all sub components including profile highlights, profile header, detail, history, and in-house. You can also add your own tabs with custom features. For example, build transactions to create a single pane for agents, so that they don't have to work with multiple systems.
• Updated the CRMContainer API component to allow clipboard access.
• Updated the twilio-chat package that's included with Flex UI to version 6.0.0 to enhance security.
• Updated the slate-react package that's included with Flex UI to version 0.66. This prevents dependency warnings when building with Flex Plugins CLI version 7.0.0 and later.

• Fixed an encoding issue in Flex UI where certain characters did not render correctly.
• Fixed an issue that caused a "No active call" error to appear in the Twilio Console error log when the caller ended an inbound call right after an agent answered.
• Fixed an issue that caused a "No next page" error to appear in the browser console log when loading older messages in a long messaging history.
• Fixed an issue where playing a Flex Insights recording on the Conversations dashboard caused the recording to stop if the administrator or supervisor opened a different Flex UI page.
• In Unified Profiles:
  • Fixed a display issue related to Customer history's manual refresh overlapping with the status panel.
  • Fixed an issue that prevented Customer history from validating proper string localization for Agent, Sentiment, Summary, and more.
  • Fixed an issue that prevented the Customer history field in Flex UI from displaying the correct date when the Date type contained incomplete information (for example, just the year).
  • Fixed an issue that caused an error to appear in the Twilio Console error log when profile highlights were disabled and an agent accepted a task.
  • Fixed an issue that caused the task list in the profile header to appear as [object Object] if the display name value is null. The task list now displays the channel address if the display name value is null.
  • Fixed a display issue with customer profile highlights where the styling was incorrect if the profile summary was only one line.
• Improved the error message that's shown when attempting to call a phone number that is blocked by Twilio.
• When the Leave option is enabled for email, if an agent clicked Leave in a task and the customer later replied, the task was incorrectly assigned to the previous agent automatically. This behavior has been corrected, so the customer reply is handled like any other new task.
• For agents using a SIP phone instead of the Voice client WebRTC to handle voice calls, outbound calls were blocked if a microphone and microphone permissions were not configured for the Voice client. This bug has been corrected and SIP phone outbound calls work as expected.
• Fixed an issue where a degraded network connection could cause access tokens to expire unexpectedly.
• Fixed an issue where holding the pointer over the headphones icon at the top of the page (also known as device manager) caused warnings to appear in the browser console.
• When an agent used a slower network connection, such as 3G, and searched for an agent during a call transfer, the search function sometimes showed unexpected results or worked slowly. We have corrected this behavior.
• Updated how telemetry events are sent so that the "Max telemetry request reached" error now occurs only in rare instances. In addition, we changed the log level of this error from log.error to log.debug.
• For Voice conference calls that include a call transfer, it wasn't possible to use webhooks to track the timeline of transfers, because Flex UI didn't transmit information about the new agent accepting the call transfer. Flex UI now sends a call status event when an agent accepts a call transfer, which makes it possible to build functionality to track call transfers.

@twilio/flex-ui@2.8.5

Release date October 9, 2024

• Fixed an issue where a degraded network connection could cause access tokens to expire unexpectedly.

@twilio/flex-ui@2.8.4

Release date September 9, 2024

• Previously, when using the Agent Copilot wrap-up notes webhook with wrap-up notes hidden in Flex UI, task-SID was missing from the HTTP request payload. This issue has been corrected.
• Flex Insights Historical Reporting now provides accurate status in the Flex UI status report when planned maintenance occurs. Previously, it incorrectly reported degraded performance during planned maintenance.

@twilio/flex-ui@2.8.3

Release date August 13, 2024

• Corrected an issue that prevented telemetry from being turned off, which could lead to rate limits being exceeded.
• Stopped useFlexSelector and useFlexDispatch from over-reporting events that occasionally caused "Rate limit exceeded" error messages to appear.

@twilio/flex-ui@2.8.2

Release date July 25, 2024

• In Flex 2.8.1, when agents attempted to transfer conversations using the Conversations Transfer plugin from the Flex Plugin Library, the transfers were unsuccessful and a "Transfer failed" message appeared. We fixed this bug to restore this Conversations Transfer functionality.
• Fixed an issue introduced in Flex UI 2.8.1 where Flex errors no longer appeared in the Twilio Console error logs.

@twilio/flex-ui@2.8.1

Release date July 11, 2024

• Fixed an issue that prevented a dependency from installing correctly.

@twilio/flex-ui@2.8.0

Release date July 11, 2024

Flex UI 2.8.0 is now available. It includes additional language support for Agent Copilot, so you can now generate wrap-up notes for Spanish and Portuguese conversations. In Unified Profiles, we've added the ability to refresh profile history, improved configurability for the profile header and recent activity, and upgraded programmability that allows you to build custom agent experiences. Throughout Flex UI, you'll also notice a number of feature and UI enhancements, bug fixes, and more.

• If you're using Agent Copilot, you can now generate the sentiment and summary for wrap-up notes in Spanish and Portuguese.
• In Unified Profiles:
  • Agents can now view customer highlights summary for outbound conversations.
  • Added the ability for agents to manually refresh the activities in a customer's profile history.
  • Enhanced Container capabilities to allow your Unified Profiles agent experience to benefit from existing Flex programmability features.
  • Administrators can now upload a CSV file to quickly load test profiles and configure the agent experience for customer profile details and history.
• Flex on Citrix VDI now supports remote devices running ChromeOS, including Chromebooks.

• Updated the behavior of the Flex UI API Reference version selector so that broken links redirect to the newest documentation for the selected version instead of showing an error message.
• In Unified Profiles, when a task comes in and a profile is associated with the customer's email address, the customer's name now appears in the task.
• Updated the Voice SDK to version 2.11.1.
• The native audio device manager that was released in public beta in Flex UI 2.6.0 is now generally available. Agents can select an audio device, such as headphones or speakers, in Flex UI.
• Updated the Citrix SDK used in Flex on Citrix VDI to version 3.1.0 to provide enhanced capabilities.
• Updated the TaskCanvasHeader button label from End Chat to End and slightly modified the button size.

• Fixed an issue that prevented legacy teams view custom filters from showing as selected after closing and reopening the filters panel.
• Fixed an issue that prevented operating system notifications from appearing when using Flex UI.
• Fixed an issue that caused some error messages to display Unknown error instead of the error details.
• In Unified Profiles:
  • Fixed an issue where the customer header only displayed First Name, Last Name, and Customer Since.
  • Fixed a search issue where phone numbers with a leading or trailing space did not locate the correct profile.
  • Fixed an issue that caused the profile header to display traits as JSON strings.
  • Fixed an issue that prevented interaction durations from appearing.
  • Fixed an issue that prevented all identifiers from appearing under Identifiers agents can search against on the Profile search tab.
  • Fixed an issue that required you to set up the Search for a Profile widget to display customer highlights and enable automatic customer search.
  • On the History tab:
    • Fixed a small resizing issue where profile events didn't expand unless they were resized.
    • Fixed a small issue where the option to expand profile events was shown for events with no details.
    • Fixed a small issue that caused an inaccurate Duration value to appear.
• Fixed an issue where a call to the ProfileEvents API didn't honor the PageSize parameter.
• Restored the functionality of the Flex.QueuesStats.[component].Content.Remove method. Beginning in Flex UI 2.5.0, this method stopped working.
• If you use Flex Insights and have customized your interactions settings in the analytics portal to drill into data, your customized links weren't clickable when accessing dashboards through Flex. We've fixed the issue, so custom interactions links are now clickable in your Flex Insights dashboards.
• Fixed a rare issue that caused the number 0 to appear in UI notifications.

• This release contains an issue that prevents dependencies from installing correctly. Please use version 2.8.1 or later instead, where this issue has been resolved.

@twilio/flex-ui@2.7.2

Release date June 5, 2024

• Fixed an issue with token refresh that sometimes occurred when intermittent network issues were present.
• Fixed an intermittent issue that prevented agents from canceling a warm transfer if the person or queue being added to the call did not answer.

@twilio/flex-ui@2.7.1

Release date May 9, 2024

• Reverted the following breaking changes:
  • manager.store.getState().flex.session.ssoTokenPayload can be undefined in Flex UI 2.7.0, which causes a TypeScript error.

• Corrected an issue that caused the Twilio Webchat React App to show the customer name incorrectly if the customer sent the last message before the chat conversation ended.
• In a rare scenario, when agents change Wi-Fi networks, have intermittent network connectivity, or become idle, they appear as unavailable for up to two minutes until the TaskRouter worker websocket can reconnect. In this release, the TaskRouter worker reconnection time has been reduced to 30 seconds. Additional logging has also been added for this connection to help better diagnose any future connection issues.

@twilio/flex-ui@2.7.0

Release date April 15, 2024

Flex UI 2.7.0 is now available. It includes AI-generated highlights and more customer data in Agent Copilot and Unified Profiles in Flex, a pause option in Email in Flex, Flex on Azure Virtual Desktop, and the option to begin using Flex's enhanced SSO configuration. You'll also notice a number of feature and UI enhancements, bug fixes, and more.

• We've added the following features to Agent Copilot (Public Beta) and Unified Profiles (Public Beta):
  • Agents have access to a new feature, customer highlights. The one-paragraph summary combines customer data and recent activity, so agents can start the conversation faster and have a more informed interaction.
  • Agents have access to more information in a customer's profile details and history:
    • Wrap-up notes now appear in a customer's history, so agents can see notes from previous interactions.
    • Agents can now see recent customer web and app activity.
    • Outbound calls now appear alongside inbound calls.
    • Past interactions in the customer's history include the queue of the agent who handled that task, in addition to the agent's name.
  • Administrators have more configuration options:
    • Show or hide wrap-up notes
    • Configure how the customer header and search, customer details, and customer history appear to agents.
  • See our documentation for information about enabling these features.
• Email in Flex now includes the ability to pause and resume a task. When enabled, the pause action enables agents to put an email task on hold while keeping it in their queue. Agents can resume the task when they're ready, which frees up their capacity to handle other tasks in the meantime.
• If your agents use Azure Virtual Desktop to log in to Flex, you can now optimize your audio calls with Flex on Azure Virtual Desktop (Public Beta).
• If your Flex instance uses legacy SSO configuration, you can now migrate to enhanced SSO configuration, a solution with enhanced security that uses OAuth 2.0 for login authorization.
• Two new metrics are available in the Real-Time Queues View, Completed (30 min) and Completed (Today), which show the number of tasks completed in the last 30 minutes or today. These metrics do not appear by default. If you want to show them, add them to your view.

• Made updates to enable Flex pages to load faster.
• Updated dependencies to enhance security.
• Upgraded the TaskRouter SDK to version 2.0.2 to provide enhanced capabilities.
• Updated the Citrix SDK used in Flex on Citrix VDI to provide enhanced capabilities.
• Updated Axios to version 1.6.7 to provide enhanced capabilities.
• Updated some login error messages to provide more detail when using enhanced SSO configuration.
• Self-hosted Flex only: If your custom application uses react-scripts v5, you must apply a workaround to use Flex 2.7.0 or later. For example, if you use a version of the Create React App that depends on react-scripts version 5, you must apply the workaround. This workaround is required due to a react-scripts issue.

• Fixed a bug that caused the summary metrics cards on the Real-Time Queues View page to revert to their previous order after a user changed their order. The cards now remain in the order that a user has configured them as long as the user continues to use the same browser and has not cleared their cookies.
• Enhanced web accessibility by improving visual contrast and correcting navigation bugs for screen readers.
• Fixed the SetInputText action in Email in Flex. This action did not work properly for Email in Flex in some previous versions of Flex UI.
• Removed the ability to switch audio devices using the native audio device manager when using Flex on Citrix VDI. The native audio device manager does not always work in Flex on Citrix VDI.
• Fixed a rare issue where voice call tasks could not be wrapped up after the call ended.
• Fixed an issue on the Real-Time Queues View page where the % of short abandoned tasks metric showed an incorrect value.
• Enhanced responsiveness of the Teams page.

@twilio/flex-ui@2.6.2

Release date May 13, 2024

• Fixed a bug that caused the summary metrics cards on the Real-Time Queues View page to revert to their previous order after a user changed their order.

• Fixed an issue on the Real-Time Queues View page where the % of short abandoned tasks metric showed an incorrect value.
• Corrected an issue that caused the Twilio Webchat React App to show the customer name incorrectly if the customer sent the last message before the chat conversation ended.
• Fixed an issue that prevented scrolling on the Quality Management > Questionnaire > Add questions page.
• Fixed the appearance of information on the Your Teams page when viewed in a small browser window. Previously, information was in some columns too small to read when viewed in a small window.
• Corrected an issue that caused a DOM error to appear when using browser developer tools on the Real-Time Queues View page when accessing a local version of Flex UI.
• Fixed an issue that caused chat conversations to unexpectedly scroll when accessing an audio or video message earlier in the conversation.

@twilio/flex-ui@2.6.1

Release date March 4, 2024

• Fixed an issue with the way that Flex on Citrix VDI handles non-fatal vdiClientDisconnected errors from Citrix. In rare situations, these errors caused Flex UI to use degraded mode until the next browser refresh.

Flex UI 2.0 support Flex Conversations and its new messaging features:

WhatsApp channel and attachments support - WhatsApp is now available as a native channel and agents can have conversations with customers using plan text or attachments. Note, currently only one attachment per message is supported.

MMS support - Agents can now send and receive MMS messages when having a conversation with the customer over SMS channel. Note, only MMS to +1 numbers is supported.

Supervisor attachment monitoring - Supervisors can now access attachments when monitoring live conversations and viewing chat transcripts

Attachment configuration - Admins can now configure attachment settings in Console per each messaging address.

Messaging UX improvements - we have improved messaging experience for agents, this includes

• New message separator and scroll to newest message button - identify which messages in the list are new and quickly scroll down to the bottom to see new messages in the conversation.
• Text and attachment in a single message - compose and send a single message that contains both text and one attachment
• Delivery failed receipts - get notified when a message has not been delivered
• Message loading indicator - now when scroll up for more messages, if loading messages takes a bit longer, we will show you a loading spinner

For more info on Flex Conversations and the new capabilities, visit Flex Conversations documentation

Conversations SDK support

Flex UI now supports Conversations SDK and Programmable Chat SDK support has been removed. If you have an existing Flex project and plugins that you wish to migrate to v2.0, follow our migration guide

For developers, we are now providing a more customizable messaging component MessageInputV2. It's a new Programmable component with 2 children

1
<MessageInputV2>
2
    <MessageInputArea key="textarea"/>
3
    <MessageInputActions key="actions"/>
4
</MessageInputV2>

MessageInputActions component is also a Programmable component and contains the message send button and the file attachment button (if file attachments are enabled). Add custom actions to this component with component add methods.

We have also introduced new default props

• use rows prop to set input field height
• use hideSendButton prop to hide Send button to free more space for your custom actions. Use it together with returnKeySendsMessage to enable sending message on Enter.

Learn more about new components in our Flex UI API docs.

In Flex UI 2.0 we are aligning to WCAG 2.1 level AA standards to support our customers in building accessible user experiences. We are gradually improving Web accessibility of our out-of-the-box Flex UI experience and tools used to customize it.

In this version we have introduced accessible color theme built with Twilio Paste including a Dark mode theme and improved accessibility support with a clearer focus state, improved keyboard navigation and screen reader support for Agent experience.

To learn more in Flex UI web accessibility.

We have introduced a Degraded mode for Flex UI - now Flex UI will initialize with limited capabilities, even if some of the components like SDK's (TaskRouter, Conversations, Voice or Sync) are down. In case of disruptions in Twilio services, Flex User will be able to login to Flex and perform certain tasks that are still available. For example, in the case of Twilio Voice experiencing an incident, your agent will still be able to handle messaging tasks.

Users will see a notification informing them of a possible disruption in the normal work of Flex UI and they will be able to download a thorough report with error details and logs.

We have updated activity controls and user profile for easier access and improved programmability.

Expand image

We have introduced a new programmable component Activity is added to MainHeader. This allows developers to replace this component with more custom activity controls that suite their business workflows.

We also made changes to the UserCard component. We have removed activity controls and changed the layout.

Note, this is a potential breaking change if you have customized UserCard and its child components using CSS. Check out our migration guide, if you are upgrading an existing Flex project to Flex UI 2.0.

We have introduced several updates to the supervisor capabilities:

• In Queue Stats, channels with no data or only 0's are no longer displayed

• In Quality Management:

  • We have allowed question sorting for questionnaire
  • Added notifications for successful and unsuccessful operations
  • Added form validation
  • Added questionnaire visibility toggle

• In Conversations Player

  • we have added a permission check for player.view.player before displaying conversation content so Player does not show with an error when user does not have permission to access recordings
  • Generate a backup waveform in the browser will now be showing when agents and customers are talking in the call recording Player. This enables Player to generate waveforms for recordings that are not accessible by Twilio backend services - encrypted by public key, copied to custom storage etc
  • Overlay Player will now support new address format of drill down links in Flex Insights Historical Reporting

In this version, we have upgrade developer tools to like twilio SDK's and major dependencies, which required a major version upgrade of a Flex UI library.

Upgraded dependencies

• Node -> >= 14
• React & React DOM -> ^17.0.0
• Redux -> ^4.0.5
• React-redux -> ^7.2.2
• React-router-redux -> removed
• Emotion -> ^11.1.3
• Material UI -> ^4.12.3

Upgraded SDK's

• Conversations SDK -> 2.1.0
• Voice SDK -> 2.0.1
• TaskRouter SDK -> ^0.5.9

For more details on all the upgraded tools, check out our migration guide

We have integrated Twilio Paste support into the Flex UI. Twilio Paste is the design system that Twilio created to support its own efforts to create consistent, inclusive, and delightful experiences. Now, Flex UI developers and partners can use the same component library for plugin development as Twilio's developers. This means that partners ensure consistent styling and branding for their customers, without having to bring in extensive UI development expertise.

Flex UI 2.0 now uses a new theming structure that more closely maps to the Twilio Paste design system. This new structure is based on the concept of design tokens, a set of variables that you can modify. This structure promotes both consistency, customization and web accessibility.

New theme config - We have introduced a new configuration key called config.theme with the following structure

1
interface ThemeConfigProps {
2
   isLight?: boolean; // Represents if light or dark theme
3
   tokens?: Tokens; // Paste tokens
4
   componentThemeOverrides?: Object; // Object containing styles of the component which is to be overridden.
5
}

Component theming - For components which receive the theme as props, props.theme.tokens is introduced. For more on each token information, please refer to Twilio Paste

Custom tokens - we have added support for customer tokens so you can pass your own custom tokens to theme using the example below

1
  appconfig = {
2
    theme: {
3
      tokens: {
4
        custom: {
5
          myCustomToken: "#ccc"
6
        }
7
      }
8
    }
9
  }

ThemeProvider - Introducing a new API Flex.setProviders() which can be used to load providers on the root level once and don't have to worry about wrapping again as the context will correctly set. Now to use Paste in Flex plugins, developers will not need to wrap Paste ThemeProvider over all its components. Check out our Theming docs for examples of how this can be used or explore the API in our Flex UI API docs.

We have added new Flex actions wrapping TaskRouter

1
import { Actions } from "@twilio/flex-ui";
2

3
// Set worker attributes
4
Actions.invokeAction("SetWorkerAttributes", { attributes: {}, mergeExisting: true });
5

6
// Update worker token
7
Actions.invokeAction("UpdateWorkerToken", { token: "newToken" });
8

9
// Update task attributes
10
Actions.invokeAction("SetTaskAttributes", { attributes: {}, mergeExisting: true });
11

12
// Issue a Call to a Worker
13
Actions.invokeAction("IssueCallToWorker", { callerId: "callerId", twiMLUrl: "twiMLUrl", options: {} });
14

15
// Dequeue the Reservation to the Worker.
16
// This will perform telephony to dequeue a Task that was enqueued using the Enqueue TwiML verb.
17
// A contact_uri must exist in the Worker's attributes for this call to go through.
18
Actions.invokeAction("DequeueTask", { options: {} })
19

20
// Redirect the active Call tied to this Reservation
21
Actions.invokeAction("RedirectCallTask", { callSid: "callSid", twiMLUrl: "twiMLUrl", options: {} });
22

23
// Update the Worker's leg in the Conference associated to this Reservation
24
Actions.invokeAction("UpdateWorkerParticipant", { options: {} });
25

26
// Update the Customer leg in the Conference associated to this Task
27
Actions.invokeAction("UpdateCustomerParticipant", { options: {} });

and introducing new Flex Events wrapping TaskRouter event

1
import { Manager } from "@twilio/flex-ui";
2
const manager = Manager.getInstance();
3

4
// Emitted when a worker receives a new task
5
manager.events.addListener("taskReceived", (task: ITask) => {});
6

7
// Emitted when the worker's activity changes
8
manager.events.addListener("workerActivityUpdated", (activity: Activity, allActivities: Map<string, Activity>) => {});
9

10
// Emitted when the worker's attributes changes
11
manager.events.addListener("workerAttributesUpdated", (newAttributes: Record<string, any>) => {});
12

13
// Emitted when the worker's task status gets updated
14
manager.events.addListener("taskUpdated", (task:ITask) => {});
15

16
// Emitted when the worker's task gets set to 'accepted'
17
manager.events.addListener("taskAccepted", (task:ITask) => {});
18

19
// Emitted when the worker's task gets set to 'canceled'
20
manager.events.addListener("taskCanceled", (task:ITask) => {});
21

22
// Emitted when the worker's task gets set to 'completed'
23
manager.events.addListener("taskCompleted", (task:ITask) => {});
24

25
// Emitted when the worker's task gets set to 'rejected'
26
manager.events.addListener("taskRejected", (task:ITask) => {});
27

28
// Emitted when the worker's task gets set to 'rescinded'
29
manager.events.addListener("taskRescinded", (task:ITask) => {});
30

31
// Emitted when the worker's task gets set to 'timeout'
32
manager.events.addListener("taskTimeout", (task:ITask) => {});
33

34
// Emitted when the worker's task gets set to 'wrapup'
35
manager.events.addListener("taskWrapup", (task:ITask) => {});

Now you can use exclusively Flex UI Actions Framework when working with TaskRouter SDK, without needing to access its methods directly.

Visit our Flex UI API docs for more details on Actions and Events

As part of the upgrades to our core APIs, Flex UI 2.0 includes the Redux Toolkit and some new APIs for managing your internal state. These tools provide some guardrails for your state management, helping you set up boilerplate code with better defaults.

useFlexSelector - A wrapper around Redux's useSelector method. It exposes the same API but adds some Flex validations to ensure Flex's internal state is usable

useFlexDispatch - A wrapper around Redux's useDispatch method. It prevents dispatches from causing side effects to Flex's state, ensuring your changes work as expected

Go to our docs to learn more about how to manage state with Flex UI, use Redux and explore the details of the new state management API's
