when<TResult extends Object?> method

  1. @optionalTypeArgs
TResult when<TResult extends Object?>(
  1. TResult $default(
    1. Elements elements,
    2. String? clientSecret,
    3. ConfirmSetupParams confirmParams,
    4. SetupConfirmationRedirect? redirect,
    )
)

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(@ElementsConverter()  Elements elements,  String? clientSecret,  ConfirmSetupParams confirmParams,  SetupConfirmationRedirect? redirect)  $default,) {final _that = this;
switch (_that) {
case _ConfirmSetupOptions():
return $default(_that.elements,_that.clientSecret,_that.confirmParams,_that.redirect);case _:
  throw StateError('Unexpected subclass');

}
}
