I wish we could tell @Preview that a composable should be shown in its focused (or pressed, or hovered) state. Where is the right place to file a feature request for that?

[Stylianos Gakis]

You can pass in your own MutableInteractionState and make that focused or something like that, then pass that into the right parameter of your composable

Aha! It seems somebody asked about this before too! https://slack-chats.kotlinlang.org/t/10972689/what-s-the-best-way-to-preview-a-focused-state-for-a-button-

[Stylianos Gakis]

Yup, I can see in our code we have some instances like this:

remember {
  object : MutableInteractionSource {
    override val interactions: Flow<Interaction>
      get() = flowOf(FocusInteraction.Focus())

    override suspend fun emit(interaction: Interaction) {
    }

    override fun tryEmit(interaction: Interaction): Boolean {
      return false
    }
  }
}

or

remember {
  object : MutableInteractionSource {
    override val interactions: Flow<Interaction>
      get() = flowOf(HoverInteraction.Enter())

    override suspend fun emit(interaction: Interaction) {
    }

    override fun tryEmit(interaction: Interaction): Boolean {
      return false
    }
  }
}

precisely for some previews
