team_guard 1.0.2

A powerful custom lint plugin for Dart and Flutter that prevents the use of forbidden widgets in your team projects. Configure which widgets are not allowed and get real-time feedback.

Team Guard

A custom lint plugin for Dart and Flutter that helps teams enforce UI rules by blocking specific widgets/classes and suggesting approved replacements.

Features

• Integrates with custom_lint for live IDE feedback.
• Supports configurable restrictions for both widgets and classes.
• Supports info, warning, and error severities per rule.
• Provides quick-fix suggestions with replacement names/imports.

Prerequisites

• Dart SDK >=3.3.0 <4.0.0
• custom_lint installed in the target project
• IDE plugin:
  • VS Code: Custom Lint
  • Android Studio / IntelliJ: Custom Lint

Installation

Add dependencies to your app's pubspec.yaml:

dev_dependencies:
  team_guard: ^1.0.1
  custom_lint: ^0.8.1

Then run:

# Flutter project
flutter pub get

# Dart project
dart pub get

Setup (Required)

1. Enable custom_lint in analysis_options.yaml:

analyzer:
  plugins:
    - custom_lint

2. Run the linter:

dart run custom_lint

3. Team Guard reads (and may create) a config file in project root:

team_guard.yaml

If the file is not generated automatically, create it manually (example below).

Configuration

Create team_guard.yaml in your project root:

widgets:
  Text:
    replacement: CustomText
    # import: package:your_app/widgets/custom_text.dart
    severity: warning

  GestureDetector:
    replacement: AppGestureDetector
    severity: error

classes:
  Colors:
    replacement: AppColors
    # import: package:your_app/theme/app_colors.dart
    severity: warning

Severity Values

• info
• warning
• error

Use error if you want violations to appear as red errors in IDE problems.

Example Violation

If Text is restricted:

Text('Hello');

You will get a lint message suggesting CustomText instead.

Troubleshooting

Lints appear in terminal but not in IDE

1. Confirm analysis_options.yaml contains:

analyzer:
  plugins:
    - custom_lint

2. Install IDE plugin Custom Lint.
3. Restart analysis:
   • VS Code: Dart: Restart Analysis Server
   • Android Studio/IntelliJ: restart IDE
4. Check Problems filter is not set to errors-only if your rules are warning.

team_guard.yaml was not generated

• Run dart run custom_lint from the project root.
• If still missing, create team_guard.yaml manually using the example above.
