Modernize Dart Code with Pattern Matching

Complex Dart branching can obscure validation, destructuring, and subtype handling. This skill selects clear patterns and checks exhaustive switch behavior.

テストする

「dart-use-pattern-matching」を使用しています。 Choose a pattern for a decoded user object containing a name and age list.

期待される結果:

Use a map pattern containing a two-element list pattern. Bind the name as String and age as int, with a fallback for invalid input.

「dart-use-pattern-matching」を使用しています。 Review area calculation for sealed Square and Circle types.

期待される結果:

Use an exhaustive switch expression because every case returns a value.
Use object patterns to extract dimensions directly.
Avoid a wildcard so newly added shape types produce an analyzer error.

作成できるもの

Validate decoded data

Convert nested data checks into map and list patterns that validate structure while extracting typed values.

Refactor branching logic

Replace repetitive conditionals with concise switch expressions, logical patterns, and guard clauses.

Review exhaustive models

Check sealed class and enum handling for missing cases before code review.

これらのプロンプトを試す

Choose a pattern

Recommend the best Dart pattern for this data shape and explain the choice: [describe data and desired result].

Refactor a conditional

Refactor this Dart conditional using pattern matching. Preserve behavior and explain whether a switch expression or statement fits: [paste code].

Validate structured data

Design Dart map and list patterns for this decoded structure. Extract required values and handle malformed input: [describe structure].

Audit exhaustiveness

Review these Dart sealed types and switch cases. Identify missing subtypes, unsafe wildcards, guard issues, and variable binding conflicts: [paste definitions].

ベストプラクティス

Run dart analyze after changing switches over sealed classes or enums.
Use guards only when the condition cannot be represented clearly as a pattern.
Prefer explicit subtype cases when future additions should trigger exhaustiveness errors.

回避

Do not use null-assert or cast patterns when failed matches should remain recoverable.
Do not add a wildcard merely to silence an exhaustiveness error.
Do not use logical-or patterns with different variable bindings across branches.

よくある質問

When should I use a switch expression?

Use one when every case produces a value and the cases can remain single expressions.

When is a switch statement better?

Use a statement for multiple operations, side effects, or case bodies that cannot be single expressions.

Can patterns validate decoded data?

Yes. Map and list patterns can verify required structure and types while binding values.

How do I check exhaustiveness?

Run dart analyze and resolve any unmatched subtype or enum value reported for the switch.

Should every switch include a wildcard?

No. Avoid wildcards when explicit cases should expose newly added sealed subtypes.

Can logical-or patterns bind variables?

Yes. Every branch must bind the same variables with compatible types.
