maybeWhen<TResult extends Object?> method

@optionalTypeArgs TResult maybeWhen<TResult extends Object?>(TResult $default(String? city, String? country, String? line1, String? line2, String? postalCode, String? state,)?, { 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? city,  String? country,  String? line1,  String? line2,  String? postalCode,  String? state)?  $default,{required TResult orElse(),}) {final _that = this;
switch (_that) {
case _Address() when $default != null:
return $default(_that.city,_that.country,_that.line1,_that.line2,_that.postalCode,_that.state);case _:
  return orElse();

}
}
