A very opinionated Collection of Linter Rules for Flutter and Dart (based on flutter_lints and lints)
Getting started
Add this package as a devDependency.
flutter pub add --dev galactic_lints
or
dart pub add --dev galactic_lints
Alternatively, you can directly add it to the devDependencies section in your pubspec.yaml:
dev_dependencies:
galactic_lints: ^0.0.1
Usage
Add the following line to your analysis_options.yaml:
include: package:galactic_lints/lints.yaml
Following that, you can still easily enable or disable rules as you please.
linter:
rules:
prefer_single_quotes: false
Additional information
Checkout the packages flutter_lints and lints.
