Some important Flow Events to use when LWC is embedded inside a screen flow

 Some important Flow Events to use when LWC is embedded inside a screen flow.

1.FlowAttributeChangeEvent:

This event is triggered when a component's property changes during the flow execution. It's vital for keeping data in sync and ensuring that components react in real-time to user input or system changes.

syntax:

 const attributeChangeEvent = new FlowAttributeChangeEvent(

 'todos',

 this._todos

 );

 this.dispatchEvent(attributeChangeEvent);

2.FlowNavigationBackEvent :

If your flow includes multiple screens, this event allows users to go back to the previous screen, offering a more fluid and user-friendly experience, especially in complex processes that require review or corrections.

3.FlowNavigationNextEvent:

This event moves the flow forward to the next screen, ensuring smooth navigation between screens without manual intervention.

syntax:

 // check if NEXT is allowed on this screen

 if (this.availableActions.find((action) => action === 'NEXT')) {

 // navigate to the next screen

 const navigateNextEvent = new FlowNavigationNextEvent();

 this.dispatchEvent(navigateNextEvent);

 }

4.FlowNavigationPauseEvent:

Sometimes, you need to pause a flow. Whether it’s waiting for a user decision or external input, this event lets you pause the flow at any point, offering flexibility in how the flow operates.

5.FlowNavigationFinishEvent:

This event signals the end of the flow. Once triggered, it effectively terminates the flow, ensuring the user knows when the process is complete, and no further actions are needed.
