when<TResult extends Object?> method

  1. @optionalTypeArgs
TResult when<TResult extends Object?>(
  1. TResult $default(
    1. String? description,
    2. String? type,
    3. String? format,
    4. Schema? schema,
    5. @JsonKey.new(name: r'$ref') String? ref,
    )
)

A switch-like method, using callbacks.

As opposed to map, this offers destructuring. It is equivalent to doing:

switch (sealedClass) {
  case Subclass(:final field):
    return ...;
  case Subclass2(:final field2):
    return ...;
}

Implementation

@optionalTypeArgs TResult when<TResult extends Object?>(TResult Function( String? description,  String? type,  String? format,  Schema? schema, @JsonKey(name: r'$ref')  String? ref)  $default,) {final _that = this;
switch (_that) {
case _Header():
return $default(_that.description,_that.type,_that.format,_that.schema,_that.ref);case _:
  throw StateError('Unexpected subclass');

}
}
