map<TResult extends Object?> method

  1. @optionalTypeArgs
TResult map<TResult extends Object?>(
  1. TResult $default(
    1. SpViewDefault value
    ), {
  2. required TResult sendKeyValue(
    1. SpSendKeyValueModel value
    ),
})

A switch-like method, using callbacks.

Callbacks receives the raw object, upcasted. It is equivalent to doing:

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

Implementation

@optionalTypeArgs
TResult map<TResult extends Object?>(
  TResult Function(SpViewDefault value) $default, {
  required TResult Function(SpSendKeyValueModel value) sendKeyValue,
}) {
  final _that = this;
  switch (_that) {
    case SpViewDefault():
      return $default(_that);
    case SpSendKeyValueModel():
      return sendKeyValue(_that);
  }
}
