when<TResult extends Object?> method

  1. @optionalTypeArgs
TResult when<TResult extends Object?>(
  1. TResult $default(
    1. String url,
    2. PatternType pattern,
    3. ActionType action,
    4. ReasonType reason,
    5. String? comment,
    6. String? createdBy,
    7. Map<String, dynamic>? $unknown,
    )
)

A switch-like method, using callbacks.

As opposed to map, this offers destructuring. It is equivalent to doing:

switch (sealedClass) {
  case Subclass(:final field):
    return ...;
  case Subclass2(:final field2):
    return ...;
}

Implementation

@optionalTypeArgs TResult when<TResult extends Object?>(TResult Function( String url, @PatternTypeConverter()  PatternType pattern, @ActionTypeConverter()  ActionType action, @ReasonTypeConverter()  ReasonType reason,  String? comment,  String? createdBy,  Map<String, dynamic>? $unknown)  $default,) {final _that = this;
switch (_that) {
case _SafelinkAddRuleInput():
return $default(_that.url,_that.pattern,_that.action,_that.reason,_that.comment,_that.createdBy,_that.$unknown);case _:
  throw StateError('Unexpected subclass');

}
