Can we somehow merge #3244 and #3243 into this? Or do I have to do it manually?

you could cherry-pick or target that PR to this branch.
another option would be, we just merge them all together, (aka keeping as it is)

Should we add some notes on Dart's null safety?
Something like sentry now requires at least Dart 1.12 and Flutter 2.0.0 ?

about Dart yes, good point, the Flutter requirement didn't change though

here we should likely need a note too: https://docs.sentry.io/platforms/dart/usage/advanced-usage/#requirements
also here https://docs.sentry.io/platforms/flutter/

maybe we add a:

<Note>

Sentry's Dart/Flutter SDK version 5.0.0 and above requires Dart 1.12.

</Note>

plus an entry to the migration page
