Hi! Does anyone know what's the use case for the parent argument in the setContent extension?

public fun ComponentActivity.setContent(
    parent: CompositionContext? = null,
    content: @Composable () -> Unit
) {...}

I've never seen a sample using this argument 🤔

It can be used to set the content as a child composition. See the source for the explanation of CompositionContext. Normally you won’t need to specify this. Here’s an example usage.

oh thanks! Will take a look at this

Yep Dialog composables use this for example. Ensures that recompositions, composition locals, etc flow from the caller into the Dialog lambda.
