SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps Dart developers replace complex conditional logic with clearer pattern matching and switch-based solutions for safer, more expressive code.

Core Features & Use Cases

Pattern Selection Guidance: Choose the right Dart pattern type for JSON validation, records, sealed classes, ranges, and value matching.
Switch Optimization: Apply switch expressions and statements appropriately for value production and side-effect execution.
Use Case: Improve Dart applications by destructuring data, handling algebraic data types, and validating inputs with exhaustive pattern matching.

Quick Start

Use the dart-use-pattern-matching skill to refactor my Dart conditional logic into idiomatic switch expressions and pattern matching.

FAQPage Schema

How do I refactor complex Dart conditional logic into pattern matching?▼

To refactor Dart conditional logic, replace nested if-else chains with switch expressions and pattern matching techniques. This involves selecting appropriate pattern types, applying guards, and validating implementations with Dart analysis tools for safer, more expressive code.

What is the best way to handle JSON validation and data destructuring in Dart?▼

The best way to handle JSON validation and data destructuring in Dart is using pattern matching. Switch expressions allow you to match specific JSON structures, validate input types exhaustively, and destructure data directly within the matching logic for clearer code.

How do switch expressions work with sealed classes in Dart?▼

Switch expressions work with sealed classes in Dart by enforcing exhaustive type checking at compile time. This ensures all subclasses are matched, allowing developers to apply type-specific behavior, destructure data safely, and prevent unhandled cases.

Can I use Dart pattern matching for record handling and range matching?▼

Yes, you can use Dart pattern matching for record handling and range matching. You can destructure records directly in switch expressions and apply guard clauses to match values within specific ranges, replacing complex conditional checks with readable syntax.

When should I use a switch expression versus a switch statement in Dart?▼

Use a switch expression in Dart when you need to produce a value from pattern matching, and use a switch statement when executing side-effects. Both support destructuring and guards, but expressions yield results directly while statements handle actions.

How do I validate exhaustive pattern matching implementations using Dart analysis tools?▼

You validate exhaustive pattern matching using Dart analysis tools by relying on the compiler to check for unhandled cases. The analyzer warnings will indicate if a switch expression covering sealed classes or records is missing required pattern types or guards.
