What flutter-app-expert-cursorrules-prompt-file does

This rule sets development guidelines for Flutter applications. It directs Cursor to use the BLoC pattern for state management and GetIt for dependency injection. Routing relies on GoRouter, while error handling uses the Either type. When creating features, it organizes code into data, domain, and presentation layers.

The prompt includes a flexibility notice: if the repository uses a different layout, the agent must adapt to it. For UI components, the rule requires const constructors where possible and accessibility checks. Business logic must be covered by unit tests, while UI elements require widget tests.

Because the configuration sets alwaysApply: false, Cursor does not automatically load these instructions into every prompt.

What it helps with

  • Scaffold feature directories into data, domain, and presentation layers
  • Implement state management using BLoC and service location with GetIt
  • Write unit and widget tests following consistent naming conventions
  • Handle application errors systematically using the Either pattern

Example prompts for the agent

  • Generate a new auth feature following clean architecture and BLoC
  • Build an optimized order history list view with image caching
  • Create unit tests and mocks for the user repository use case

Questions about flutter-app-expert-cursorrules-prompt-file

How to install flutter-app-expert-cursorrules-prompt-file in Cursor?

Create .cursor/rules/flutter-app-expert-cursorrules-prompt-file.mdc in your project root and paste the rule contents into it.

What does flutter-app-expert-cursorrules-prompt-file do?

It instructs Cursor to follow Flutter 3.x conventions, BLoC state management, Clean Architecture, and testing guidelines.

Does this rule overwrite existing project architectures?

No, the rule explicitly tells the AI to adapt to the existing project structure instead of enforcing its reference layout.
