SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps Dart developers replace verbose conditional logic with expressive pattern matching and switch constructs, improving code clarity, safety, and maintainability.

Core Features & Use Cases

Pattern Selection Guidance: Choose the right Dart pattern type for JSON validation, records, classes, enums, collections, and conditional matching.
Switch Optimization: Apply switch expressions for value generation and switch statements for side effects with proper exhaustiveness handling.
Use Case: Use this Skill when refactoring Dart code that processes API responses, models sealed class hierarchies, or needs safer destructuring of complex data structures.

Quick Start

Use the dart-use-pattern-matching skill to refactor this Dart conditional logic into idiomatic pattern matching.

FAQPage Schema

How do I use pattern matching in Dart for JSON parsing?▼

Dart pattern matching improves JSON parsing by validating and destructuring complex data structures safely. Switch expressions help generate values from API responses, replacing verbose conditional logic with clearer control flow.

How do I refactor Dart code to use switch expressions and sealed classes?▼

Refactoring Dart code with switch expressions and sealed classes enforces exhaustive matching for safer control flow. This approach handles class hierarchies precisely while ensuring all possible cases are covered during value generation or side effects.

What's the best way to handle record destructuring in Dart?▼

Record destructuring in Dart is best handled by applying appropriate pattern selection for complex data structures. Pattern matching replaces verbose logic with expressive constructs, ensuring safer and clearer extraction of record fields.

Does Dart pattern matching require exhaustive switch statements?▼

Yes, Dart pattern matching requires exhaustive matching for reliable implementations. Switch statements handling side effects and switch expressions generating values must cover all cases, validated through Dart analysis to ensure complete control flow.

When do I need pattern matching for enums and collections in Dart?▼

You need pattern matching for enums and collections in Dart when replacing verbose conditional logic with safer destructuring. It applies appropriate pattern selection for conditional matching, transforming logic into clearer and more maintainable code.
