Dart SDK version is 3.4.0 #3
Description
Resolving dependencies...
The current Dart SDK version is 3.4.0.
Because flutter_module depends on dio_cookie_manager >=1.0.0 <2.0.0-beta1 which doesn't support null safety, version solving failed.
The lower bound of "sdk: '>2.4.0 <3.0.0'" must be 2.12.0 or higher to enable null safety.
