maybeWhen<TResult extends Object?> method

  1. @optionalTypeArgs
TResult maybeWhen<TResult extends Object?>(
  1. TResult $default(
    1. String $type,
    2. String? appealSubmittedBy,
    3. String? appealActionType,
    4. int? appealActionId,
    5. String? appealLabel,
    6. String? comment,
    7. bool? isReporterMuted,
    8. @ReasonTypeConverter() ReasonType reportType,
    9. Map<String, dynamic>? $unknown,
    )?, {
  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 $type,  String? appealSubmittedBy,  String? appealActionType,  int? appealActionId,  String? appealLabel,  String? comment,  bool? isReporterMuted, @ReasonTypeConverter()  ReasonType reportType,  Map<String, dynamic>? $unknown)?  $default,{required TResult orElse(),}) {final _that = this;
switch (_that) {
case _ModEventReport() when $default != null:
return $default(_that.$type,_that.appealSubmittedBy,_that.appealActionType,_that.appealActionId,_that.appealLabel,_that.comment,_that.isReporterMuted,_that.reportType,_that.$unknown);case _:
  return orElse();

}
