Null safe packages throw error: "Cannot run with sound null safety"-CodePudding

Error: Cannot run with sound null safety, because the following dependencies
don't support null safety:

 - package:hooks_riverpod
 - package:flutter_riverpod
 - package:riverpod

I don't understand, these packages shouldn't have this problem, they are null safe.

And when I run flutter run --no-sound-null-safety getting a bunch of errors starting with this one:

/D:/src/flutter/.pub-cache/hosted/pub.dartlang.org/ri
verpod-0.12.4/lib/src/common.freezed.dart:121:4: Erro
r: Getter not found: 'nullable'.

CodePudding user response：

If these packages do not support null safety, you will have to stay on the old version of flutter or discard these dependencies until the developers update the dependencies, if null safety is supported try to make a migration https://dart.dev/null-safety/migration-guide

CodePudding user response：

Update your packages to the versions that support null-safety.
