Until compose-beta01 it was very easy to hoist the pressed state in Jetpack Compose using InteractionState
:
@Composable
fun App() {
val interactionState = remember { InteractionState() }
val pressed = interactionState.contains(Interaction.Pressed)
MyComposable(Modifier.clickable(interactionState = interactionState) { })
}
InteractionState was removed in beta01 and there is now obvious way to replicate this behaviour. How can I hoist the pressed state using the clickable
modifier?
Have you tried applying what's explained in the release notes of Compose beta01 ?
InteractionState
has been replaced with[Mutable]InteractionSource
- Interfaces are responsible for emitting / collecting Interaction events.
- Instead of passing
interactionState = remember { InteractionState() }
to components such asButton
andModifier.clickable()
, useinteractionSource = remember { MutableInteractionSource() }
.- Instead of:
Interaction.Pressed in interactionState
you should instead use the extension functions on InteractionSource, such as InteractionSource.collectIsPressedAsState().- For complex use cases you can use InteractionSource.interactions to observe the stream of Interactions. See the InteractionSource documentation and samples for more information.

So, in your example, I would try something like:
val interactionSource = remember { MutableInteractionSource() }
val pressedState = interactionSource.collectIsPressedAsState()
MyComposable(
Modifier.clickable(
interactionSource = interactionSource,
indication = LocalIndication.current
) {}
)
