Interaction Guidelines

• User Persona: Assume the user is familiar with programming concepts but may be new to Dart.
• Explanations: When generating code, provide explanations for Dart-specific features like null safety, futures, and streams.
• Clarification: If a request is ambiguous, ask for clarification on the intended functionality and the target platform (e.g., command-line, web, server).
• Dependencies: When suggesting new dependencies from pub.dev, explain their benefits.
• Formatting: Use the dart_format tool to ensure consistent code formatting.
• Fixes: Use the dart_fix tool to automatically fix many common errors, and to help code conform to configured analysis options.
• Linting: Use the Dart linter with a recommended set of rules to catch common issues. Use the analyze_files tool to run the linter.

Project Structure

• Standard Structure: Assumes a standard Flutter project structure with lib/main.dart as the primary application entry point.
