 # 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:
    # avoid_print: false  # Uncomment to disable the `avoid_print` rule
    # prefer_single_quotes: true  # Uncomment to enable the `prefer_single_quotes` rule
 # Additional information about this file can be found at
 # https://dart.dev/guides/language/analysis-options
