maybeWhen<TResult extends Object?> method

  1. @optionalTypeArgs
TResult maybeWhen<TResult extends Object?>(
  1. TResult $default(
    1. bool? isPrimary,
    2. String? fullAddress,
    3. String? addressId,
    4. String? line1,
    5. String? line2,
    6. String? city,
    7. String? state,
    8. String? postalCode,
    9. String? country,
    10. bool? isSelected,
    )?, {
  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();
}
