02/17/2021, 2:52 PMHi all, I'm currently working on a launcher app in Compose. In order to move an app from the app drawer to the home screen I'd need to be able to drag and drop an element from one composable to another one (not sure if the terminology is correct here). Any idea how to do that? I would need the full experience, with a drop shadow and everything and I can't seem to find anything that remotely compares to the system that existed in the traditional view system.

I think this is a good idea, although there are several challenges there, like figuring out which cell we are in when the user "drops" the app.
