maybeWhen<TResult extends Object?> method

TResult maybeWhen<TResult extends Object?>(
  1. TResult $default(
    1. String? description,
    2. bool? required,
    3. bool? deprecated,
    4. String? style,

    10. @JsonKey.new(name: r'$ref') String? ref,
    )?, {
  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? description,  bool? required,  bool? deprecated,  String? style,  bool? explode,  Schema? schema,  dynamic example,  Map<String, Example>? examples,  Map<String, MediaType>? content, @JsonKey(name: r'$ref')  String? ref)?  $default,{required TResult orElse(),}) {final _that = this;
switch (_that) {
case _Header() when $default != null:
return $default(_that.description,_that.required,_that.deprecated,_that.style,_that.explode,_that.schema,_that.example,_that.examples,_that.content,_that.ref);case _:
  return orElse();
