Flutter crash-free users %

I’m looking at the releases page on my Sentry dashboard and none of the releases show Adoption/Crash Free Rate/Crashes. Am I missing some configuration steps?

My app is a Flutter app.

Unfortunately this is currently not supported.
See these issues for more information:

if it’s a Flutter App for Android/iOS or macOS, it does, when using sentry_flutter | Flutter Package

the difference is that the Crashes are only calculated if there were a hard crash (process terminated) on the native layers, and not on eg runZonedGuarded#onError which does not Crash the App and the process remains alive.
