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:
- Depend on this package as a dev_dependency by running
flutter pub add --dev flutter_lints_plus
. - Create an
analysis_options.yaml
file at the root of the package (alongside thepubspec.yaml
file) andinclude: 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.

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
