Analysis suggestions

Package not compatible with SDK dart

because of import path [extended_transitions] that is in a package requiring null.

Health suggestions

Format lib/coupled_transition/coupled_transition_controller.dart.

Run flutter format to format lib/coupled_transition/coupled_transition_controller.dart.

Format lib/coupled_transition/transition.dart.

Run flutter format to format lib/coupled_transition/transition.dart.

Maintenance suggestions

The package description is too short. (-15 points)

Add more detail to the description field of pubspec.yaml. Use 60 to 180 characters to describe the package, what it does, and its target use case.

Maintain an example. (-10 points)

Create a short demo in the example/ directory to show how to use this package.

Common filename patterns include main.dart, example.dart, and extended_transitions.dart. Packages with multiple examples should provide example/README.md.

For more information see the pub package layout conventions.

Package is pre-v0.1 release. (-10 points)

While nothing is inherently wrong with versions of 0.0.*, it might mean that the author is still experimenting with the general direction of the API.
