when<TResult extends Object?> method

  1. @optionalTypeArgs
TResult when<TResult extends Object?>(
  1. TResult $default(
    1. String $type,
    2. @EnforcementViewStateConverter() EnforcementViewState state,
    3. @EnforcementViewScopeConverter() EnforcementViewScope? scope,
    4. @JsonKey.new(toJson: iso8601) DateTime? expiresAt,
    5. List<String>? labels,
    6. 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 $type, @EnforcementViewStateConverter()  EnforcementViewState state, @EnforcementViewScopeConverter()  EnforcementViewScope? scope, @JsonKey(toJson: iso8601)  DateTime? expiresAt,  List<String>? labels,  Map<String, dynamic>? $unknown)  $default,) {final _that = this;
switch (_that) {
case _EnforcementView():
return $default(_that.$type,_that.state,_that.scope,_that.expiresAt,_that.labels,_that.$unknown);case _:
  throw StateError('Unexpected subclass');

}
