go_router_linter 0.1.6

A custom linting package designed to enhance code quality and consistency when using the `go_router` package

Go Router Linter

go_router_linter is a custom linting package designed to enhance code quality and consistency when using the go_router package in Dart and Flutter applications. It encourages best practices by identifying and suggesting improvements for common patterns.

Features

Current Rules

1. Ensure GoRoute Includes a name Property

• Lint Code: missing_go_route_name_property
• What it does: Detects GoRoute definitions missing the name property and suggests adding it for better readability and routing consistency.

Example:

// Bad
GoRoute(
  path: '/home',
  builder: (context, state) => HomePage(),
);

// Good
GoRoute(
  path: '/home',
  name: 'home',
  builder: (context, state) => HomePage(),
);

2. Use context.go() Instead of GoRouter.of(context).go()

• Lint Code: use_context_directly_for_go_router
• What it does: Detects instances where GoRouter.of(context).go() is used and suggests replacing it with the more concise context.go().

Example:

// Bad
GoRouter.of(context).go('/home');

// Good
context.go('/home');

3. Avoid Hardcoded Routes

• Lint Code: avoid_hardcoded_routes

• What it does: Detects when hardcoded route strings are used directly in:

  • context.go(), context.push(), context.goNamed(), context.pushNamed(), etc.
  • GoRouter.of(context).go(), GoRouter.of(context).push(), GoRouter.of(context).goNamed(), GoRouter.of(context).pushNamed(), etc.
  • GoRoute definitions (path and name properties)

  and suggests using constants or enums instead.

Examples:

// Bad: Hardcoded string in go()
context.go('/profile');

// Good: Use a constant or enum
context.go(AppRoutes.profile);

// Bad: Hardcoded string in GoRoute definition
GoRoute(
  path: '/details',
  name: 'details',
  builder: (context, state) => DetailsPage(),
);

// Good: Use a constant or enum
GoRoute(
  path: AppRoutes.detailsPath,
  name: DetailsPage.name,
  builder: (context, state) => DetailsPage(),
);

Installation

To integrate go_router_linter into your project, follow these steps:

1. Add Dependency

In your pubspec.yaml file, include go_router_linter under dev_dependencies:

dev_dependencies:
  go_router_linter: ^0.1.0

2. Update analysis_options.yaml

Enable the custom lint rules by adding the following to your analysis_options.yaml file:

analyzer:
  plugins:
    - custom_lint

custom_lint:
  rules:
    - missing_go_route_name_property
    - use_context_directly_for_go_router
    - avoid_hardcoded_routes

Usage

After setting up, the linter will automatically analyze your code and provide warnings or suggestions based on the defined rules.

Missing name Property

If a GoRoute definition does not include the name property:

GoRoute(
  path: '/profile',
  builder: (context, state) => ProfilePage(),
);

The linter will produce the following suggestion:

GoRoute definition should include a name property.

Using GoRouter.of(context).go()

If GoRouter.of(context).go() is detected:

GoRouter.of(context).go('/home');

The linter will suggest replacing it with:

context.go('/home');

Avoiding Hardcoded Routes

If a hardcoded route string is detected in context.go('/profile'):

Avoid hardcoded route paths. Use constants or enums for routes.

If a hardcoded route string is detected in a GoRoute definition:

Avoid hardcoded route paths. Use constants or enums for routes.
