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.
