this bug is fixed and will be released in alpha09

Ash · Answer

So everyone using bottom navigation androidx compose material BottomNavigationKt is getting this error And must wait for alpha09 for the fix or am I missing something

Andrey Kulikov · Answer

it is a bit random and is reproducible in some conditions if you face it it is safer to stay on alpha07 for now and wait for alpha09 as there is no good workaround
