# 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-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:

    prefer_const_constructors: false

    prefer_const_literals_to_create_immutables: false

    # avoid_print: false  # Uncomment to disable the `avoid_print` rule

    # prefer_single_quotes: true  # Uncomment to enable the `prefer_single_quotes` rule
