Jetpack compose dialogFragment equivalent

Question

I'm trying to implement a dialogFragment with custom layout in Jetpack compose but can't find any samples. Do I need to wrap the UI components inside a Card/Surface and then wrap that inside a Dialog? Can't find any examples in the documentation, all the samples are about Alert dialogs but I need to customise the layout. Thanks.

Answer 1

You can use the Dialog composable:

Dialog(
    onDismissRequest = { /* ... */ },
    DialogProperties(dismissOnBackPress = true, dismissOnClickOutside = false)
) {
    /* Your custom layout */
}
