when<TResult extends Object?> method

  1. @optionalTypeArgs
TResult when<TResult extends Object?>(
  1. TResult $default(
    1. String? requestId,
    2. @JsonKey.new(name: 'action') String? actionName,
    3. HostActionStatus status,
    4. String? message,
    5. String? errorCode,
    6. Map<String, dynamic> data,
    )
)

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? requestId, @JsonKey(name: 'action')  String? actionName,  HostActionStatus status,  String? message,  String? errorCode,  Map<String, dynamic> data)  $default,) {final _that = this;
switch (_that) {
case _HostActionResult():
return $default(_that.requestId,_that.actionName,_that.status,_that.message,_that.errorCode,_that.data);case _:
  throw StateError('Unexpected subclass');

}
}
