I have changed pubspec.yaml, then ran flutter clean and flutter pub get. It worked.

...
# another_flushbar: ^1.10.29 # before
another_flushbar: 1.10.28 # after 
# or
another_flushbar: <=1.10.28 # etc.

https://github.com/cmdrootaccess/another-flushbar/commit/22c547036591bb482c01fc2263532cffab74731e#diff-31c0a3f2a09ed06c40eaf4a0ef3a079e92097ac3779f18028d73ced2e457b45a

I guess this commit has changed the relevant code, then it started getting errors with Flutter which versions under 3.0.0.

I propose to add a constraint on the version of Flutter in pubspec.yaml as follows,

environment:
  sdk: ...
  flutter: '>=3.0.0'

Please upgrade to flutter 3 and this issue will be resolved
