Issues

Users can only select reaction emojis from a small set of hardcoded reactions.

Solutions

Add a full emoji keyboard / emoji picker.

As I wrote down in this article. I couldn't find a perfect emoji picker with recent emoji, search, compose support, etc.

I went with the Google-provided Emoji2 Picker, which doesn't have search support, nor first-class compose support, but looks nice and it's simple to use.

The issue with scrolling

Material3's ModalBottomSheet does not support disabling the swipe up/down gesture. The swipe gesture conflicts with the emoji picker scroll, making it almost useless.

After some days fiddling with it, I attempted to use different bottom sheets using Compose, until I eventually gave up and switched to BottomSheetDialog (not Compose).

This one was easy to enable/disable the dragging using the BottomSheetBehavior. But in order to keep it draggable by the top handle, required the creation of a DraggableByHandleBottomSheetBehavior, which checks if the touch is inside the DragHandle or not.

Also, one dark theme definition was needed in order to get the right contrasting text colors in the bottom sheet / emoji picker.
