This is a custom linter package for dart/flutter code. It can set linter for exclude some of words. This words you can set in analysis_options.yaml by example below

dev_dependencies:
  cool_linter: ^1.2.0 # last version of plugin

analyzer:
  plugins:
    - cool_linter

cool_linter:
  extended_rules:
    - always_specify_stream_subscription
    - prefer_trailing_comma
  always_specify_types:
    - typed_literal
    - declared_identifier
    - set_or_map_literal
    - simple_formal_parameter
    - type_name
    - variable_declaration_list
  regexp_exclude:
    -
      pattern: Colors
      hint: Use colors from design system instead!
      severity: WARNING
    -
      pattern: Test123{1}
      severity: ERROR
  exclude_folders:
    - test/**
    - lib/ku/**

1. always_specify_types linter:

always_specify_types This rule is like dart core linter rule, but you can choose which of this subrules want to use:

• typed_literal
• declared_identifier
• set_or_map_literal
• simple_formal_parameter
• type_name
• variable_declaration_list

Also you can choose exclude folders for this rule. See exclude_folders

2. regexp_exclude linter:

• pattern - RegExp-pattern, for example: Test123{1}, ^Test123$ and others
• severity - [optional parameter]. It is console information level. May be WARNING, INFO, ERROR. Default is WARNING
• hint - [optional parameter]. It is console information sentence
• exclude_folders - this folders linter will ignore. By default excluded folders are:

'.dart_tool/**',
'.vscode/**',
'packages/**',
'ios/**',
'macos/**',
'web/**',
'linux/**',
'windows/**',
'go/**',

3. extended_rules. always_specify_stream_subscription linter:

Always use StreamSubscription for Stream.listen();

CORRECT:

final Stream<String> stream2 = Stream<String>.value('value');
final StreamSubscription<String> sub = stream2.listen((_) {}); // OK

WARNING:

final Stream<String> stream1 = Stream<String>.value('value');
stream1.listen((String ttt) {}); // LINT

You can use linter as command line tool dart bin/cool_linter_cli.dart analyze -tsc -d test/fix/result --regexp_path test/regexp/regexp_settings_cli.yaml

or using dart pub run

💪 available autofix 💪 for:

• prefer_trailing_comma
• always_specify_types_rule

for this subrules: declared_identifier simple_formal_parameter variable_declaration_list

for others subrules feel free to provide me PRs

Available options:

• -d - Folder to analyze
• -f - Fix issues. Now only for prefer_trailing_comma rule
• -t - Use always_specify_types_rule rule
• -s - Use always_specify_stream_subscription rule
• -c - Use prefer_trailing_comma rule
• -f - Fix issues. Now only for prefer_trailing_comma rule
• --regexp_path - Path to file with RegExp settings

Also you must specify --regexp_path parameter if you want to regexp analyzer. Example: --regexp_path <path to regexp settings .yaml file>

regexp_exclude:
  -
    pattern: Colors
    hint: Use colors from design system instead!
    severity: WARNING
  -
    pattern: \sTestClass\s
    hint: Dont use TestClass
    severity: ERROR
  -
    pattern: \sTestClass2\s
    hint: Dont use TestClass2
    severity: INFO
