maybeWhen<TResult extends Object?> method

@optionalTypeArgs TResult maybeWhen<TResult extends Object?>(TResult $default(String category, @JsonKey.new(name: 'total_items') int totalItems, @JsonKey.new(name: 'start_date') String startDate, @JsonKey.new(name: 'end_date') String endDate, @JsonKey.new(name: 'total_count') int totalCount, Map<String, int> items,)?, { 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 category, @JsonKey(name: 'total_items')  int totalItems, @JsonKey(name: 'start_date')  String startDate, @JsonKey(name: 'end_date')  String endDate, @JsonKey(name: 'total_count')  int totalCount,  Map<String, int> items)?  $default,{required TResult orElse(),}) {final _that = this;
switch (_that) {
case _AnalyticsData() when $default != null:
return $default(_that.category,_that.totalItems,_that.startDate,_that.endDate,_that.totalCount,_that.items);case _:
  return orElse();

}
