How to solve this problem. When I run flutter pub get this error will be shown. I have changed the environment:

    You need to do either downgrade flutter version or need to update animated_floatbutton plugin for latest flutter version.because this plugin version not supported for flutter version 2.12.0

    The package specified in the issue (animated_floatactionbuttons) should be upgraded to a version that is compatible with your current Dart SDK version.

    The animated_floatactionbuttons version is not null safety enabled while your SDK version is null safety enabled.

    Solution will be to upgrade the aimated_floatactionbuttons package version to a version that meet your current Dart SDK requirements. If there are no updated version of this package, then I think you need to find an alternative package to make use of.
