amplify_lints 2.0.1

The lint rules used in developing Amplify Flutter packages and plugins.

AWS Amplify Lints

Lints used throughout Flutter packages and plugins.

Lints

The linter rules in this package are derived from the Dart team's lints package (for Dart packages) and flutter_lints (for Flutter apps/plugins/packages). A link to the description for each of the additional linter rules is provided below. More detail about linter rules can be found on the official linter rules homepage.
