maybeWhen<TResult extends Object?> method

  1. @optionalTypeArgs
TResult maybeWhen<TResult extends Object?>(
  1. TResult $default(
    1. String name,
    2. String command,
    3. String? description,
    4. List<String>? runInPackages,
    5. String? runHooksFrom,
    6. List<String>? scripts,
    7. bool all,
    8. Map<String, String>? env,
    )?, {
  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 name,  String command,  String? description,  List<String>? runInPackages,  String? runHooksFrom,  List<String>? scripts,  bool all,  Map<String, String>? env)?  $default,{required TResult orElse(),}) {final _that = this;
switch (_that) {
case _Script() when $default != null:
return $default(_that.name,_that.command,_that.description,_that.runInPackages,_that.runHooksFrom,_that.scripts,_that.all,_that.env);case _:
  return orElse();

}
