SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill addresses the complexity of writing boilerplate-heavy Flutter widget tests, ensuring that UI components render correctly and respond to user interactions as expected.

Core Features & Use Cases

  • Component Validation: Verify that specific widgets display the correct data and state.
  • Interaction Simulation: Programmatically simulate taps, text entry, scrolling, and drag gestures.
  • Use Case: Use this when you need to ensure that a custom form or list view correctly updates its state after a user interaction, such as adding an item to a todo list or dismissing a card.

Quick Start

Use the flutter-add-widget-test skill to generate a test file for the MyCustomButton widget that verifies it triggers a callback when tapped.
