maybeWhen<TResult extends Object?> method

  1. @optionalTypeArgs
TResult maybeWhen<TResult extends Object?>(
  1. TResult $default(
    1. String body,
    2. String bodySummary,
    3. DateTime createdAt,
    4. String handle,
    5. String id,
    6. String title,
    7. DateTime updatedAt,
    8. String onlineStoreUrl,
    )?, {
  2. required TResult orElse(),
})

A variant of when that fallback to an orElse callback.

It is equivalent to doing:

switch (sealedClass) {
  case Subclass(:final field):
    return ...;
  case _:
    return orElse();
}

Implementation

@optionalTypeArgs TResult maybeWhen<TResult extends Object?>(TResult Function( String body,  String bodySummary,  DateTime createdAt,  String handle,  String id,  String title,  DateTime updatedAt,  String onlineStoreUrl)?  $default,{required TResult orElse(),}) {final _that = this;
switch (_that) {
case _Page() when $default != null:
return $default(_that.body,_that.bodySummary,_that.createdAt,_that.handle,_that.id,_that.title,_that.updatedAt,_that.onlineStoreUrl);case _:
  return orElse();

}
}
