PairedConditionalConverter class abstract

A bridge interface combining PairedConverter and ConditionalConverter.

Use this when writing a paired converter that should only match under specific conditions.

🔧 Example:

class ConditionalUriConverter extends ConditionalPairedConverter {
  @override
  Set<ConvertiblePair> getConvertibleTypes() => {
    ConvertiblePair(Class<String>(), Class<Uri>())
  };

  @override
  bool matches(TypeDescriptor sourceType, TypeDescriptor targetType) {
    return sourceType.type == String && targetType.type == Uri;
  }

  @override
  Object? convert(Object? source, TypeDescriptor sourceType, TypeDescriptor targetType) {
    return Uri.tryParse(source as String);
  }
}
