tabSelectionEvents

Create a Flow of tab selection events on the TabLayout instance where the value emitted is one of the 3 event types: TabLayoutSelectionEvent.TabSelected, TabLayoutSelectionEvent.TabReselected, TabLayoutSelectionEvent.TabUnselected

Note: if a a tab is already selected, TabLayoutSelectionEvent.TabSelected will be emitted immediately upon collection.

Note: Created flow keeps a strong reference to the TabLayout instance until the coroutine that launched the flow collector is cancelled.

Example of usage:

// observe all 3 types of events
tabLayout.tabSelectionEvents()
     .onEach { event ->
         when(event) {
             is TabLayoutSelectionEvent.TabSelected -> {
                 // handle selected event
             }
             is TabLayoutSelectionEvent.TabReselected -> {
                 // handle reselected event
             }
             is TabLayoutSelectionEvent.TabUnselected -> {
                 // handle unselected event
             }
         }
     }
    .launchIn(uiScope)

// only observe 1 type of events tabLayout.tabSelectionEvents() .filterIsInstance() .onEach { event -> // handle selected event } .launchIn(uiScope)
