I'm using 
ModalBottomSheetLayout
with 
BottomSheetScaffold
. I have a 
TextField
in the sheetContent of 
BottomSheetScaffold
but I'm getting a crash when the 
TextField
goes out of focus or I hide the keyboard. Is this a bug or am I not supposed to use 
ModalBottomSheet
and 
BottomSheetScaffold
together?
Copy code
java.util.NoSuchElementException: Key 2072.0 is missing in the map.

Based on your experience and mine, I think there's a reason why 
ModalBottomSheetLayout
requires 
@ExperimentalMaterialApi
.... Seems buggy,
s
Well there are still bugs in some parts of compose especially keyboards. There was a similar 
TextField
related crash in 
AlertDialog
. I'm not sure if it has been fixed but it could be the same bug
z
That definitely looks like a bug to me, can you file an issue? The link is in the channel topic.

Heh, there's an issue for this I think
https://issuetracker.google.com/issues/180488877 I think this is the same issue No easy workaround afaik😞
s
Yep looks the same but I'll file an issue anyway
