The current Dart SDK version is 2.19.3.

Because clean_architecture_todo_app depends on build_runner >=2.4.0 which requires SDK version >=3.0.0-134.0.dev <4.0.0, version solving failed.

Because every version of flutter_test from sdk depends on path 1.8.2 and clean_architecture_todo_app depends on path ^1.8.3, flutter_test from sdk is forbidden.
