This package contains a recommended set of lints for Flutter apps, packages, and plugins to encourage good coding practices.

This package is built on top of Flutter's flutter_lints set of lints from [package:flutter_lints].

Lints are surfaced by the dart analyzer, which statically checks dart code. Dart-enabled IDEs typically present the issues identified by the analyzer in their UI. Alternatively, the analyzer can be invoked manually by running flutter analyze.

Usage

These lints by following these instructions:

1. Depend on this package as a dev_dependency by running flutter pub add --dev flutter_lints_plus.
2. Create an analysis_options.yaml file at the root of the package (alongside the pubspec.yaml file) and include: package:flutter_lints_plus/flutter.yaml from it.

Example analysis_options.yaml file:

# This file configures the analyzer, which statically analyzes Dart code to
# check for errors, warnings, and lints.
#
# The issues identified by the analyzer are surfaced in the UI of Dart-enabled
# IDEs (https://dart.dev/tools#ides-and-editors). The analyzer can also be
# invoked from the command line by running `flutter analyze`.

# The following line activates a set of recommended lints for Flutter apps,
# packages, and plugins designed to encourage good coding practices.
include: package:flutter_lints_plus/flutter.yaml

linter:
  # The lint rules applied to this project can be customized in the
  # section below to disable rules from the `package:flutter_lints_plus/flutter.yaml`
  # included above or to enable additional rules. A list of all available lints
  # and their documentation is published at
  # https://dart-lang.github.io/linter/lints/index.html.
  #
  # Instead of disabling a lint rule for the entire project in the
  # section below, it can also be suppressed for a single line of code
  # or a specific dart file by using the `// ignore: name_of_lint` and
  # `// ignore_for_file: name_of_lint` syntax on the line or in the file
  # producing the lint.
  rules:
    # avoid_print: false  # Uncomment to disable the `avoid_print` rule
    # prefer_single_quotes: true  # Uncomment to enable the `prefer_single_quotes` rule
