dart-3-patterns

What problem does it solve?

This Skill simplifies complex data handling and conditional logic in Dart by leveraging the advanced pattern matching features introduced in Dart 3, making code more readable, concise, and robust.

Core Features & Use Cases

• Exhaustive Switches: Ensures all possible cases are handled, especially with enums and sealed classes, preventing runtime errors.
• Data Destructuring: Easily extract values from lists, records, and objects into separate variables.
• Conditional Logic: Write more expressive if-case statements for type checking and value extraction.
• Use Case: When dealing with a Result type that can be either Success(data) or Error(message), use pattern matching to cleanly handle both outcomes and extract the relevant data or message.

Quick Start

Use the dart-3-patterns skill to demonstrate a switch statement with pattern matching on a sealed class.
