galactic_lints 1.0.0

A very opinionated Collection of Linter Rules for Flutter and Dart that go beyond.

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.
