I'm receiving some crashes that I cannot relate to our own code, but it happens fairly often. It mostly seems to occur when the UI is updated rapidly, but I'm unable to reproduce it consistently.
I'm using
- Compose version 1.0.0-alpha10
- AGP version 7.0.0-alpha04
The stacktrace:
Fatal Exception: java.lang.IllegalArgumentException: e@b4fb400 children: 4 measureBlocks: MeasuringIntrinsicsMeasureBlocks@34b1caf{ measureBlock=b.e.b.t.f$c@812b8bc } is not ready. layoutState is NeedsRelayout
