when<TResult extends Object?> method

  1. @optionalTypeArgs
TResult when<TResult extends Object?>(
  1. TResult $default(
    1. String? profileID,
    2. bool? allowWhatsApp,
    3. bool? allowText,
    4. bool? allowPush,
    5. bool? allowEmail,
    )
)

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(@JsonKey(name: 'profileID')  String? profileID, @JsonKey(name: 'allowWhatsApp')  bool? allowWhatsApp, @JsonKey(name: 'allowTextSMS')  bool? allowText, @JsonKey(name: 'allowPush')  bool? allowPush, @JsonKey(name: 'allowEmail')  bool? allowEmail)  $default,) {final _that = this;
switch (_that) {
case _CommunicationSettings():
return $default(_that.profileID,_that.allowWhatsApp,_that.allowText,_that.allowPush,_that.allowEmail);case _:
  throw StateError('Unexpected subclass');

}
}
