For the LargeTopAppBar, please consider providing 2 composable slots (as internally it uses TwoRowsTopAppBar) so that we can use different content for different states.

The most common use case might be showing a backdrop image in the expanded state, while showing only text in the collapsed state.

Why is TwoRowsTopAppBar even private and not public... Related: STOP MAKING ALL USEFUL APIS INTERNAL

Marked as fixed.

Added TwoRowsTopAppBar API here.

This should allow more flexibility when creating top app bars with two rows.
