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.

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.

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.

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.

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.

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.
