flutter_lints

Description:

flutter lints

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 Dart's recommended.yaml set of lints from
package: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 #
Flutter apps, packages, and plugins created with flutter create starting with
Flutter version 2.3.0 are already set up to use the lints defined in this
package. Entities created before that version can use these lints by following
these instructions:

Depend on this package as a dev_dependency by running
flutter pub add dev:flutter_lints.
Create an analysis_options.yaml file at the root of the package (alongside
the pubspec.yaml file) and include: package:flutter_lints/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/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/flutter.yaml`
# included above or to enable additional rules. A list of all available lints
# and their documentation is published at https://dart.dev/tools/linter-rules.
#
# 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

Adding new lints #
Please file a lint proposal issue to suggest that an existing lint rule should
be added to this package. The benefits and risks of adding a lint should be
discussed on that issue with all stakeholders involved. The suggestions will be
reviewed periodically (typically once a year). Following a review, the package
will be updated with all lints that made the cut.
Adding a lint to the package may create new warnings for existing users and is
therefore considered to be a breaking change, which will require a major version
bump. To keep churn low, lints are not added one-by-one, but in one batch
following a review of all accumulated suggestions since the previous review.
