whenOrNull<TResult extends Object?> method

@optionalTypeArgs TResult? whenOrNull<TResult extends Object?>(TResult? $default(Schema? schema, dynamic example, Map<String, Example>? examples, Map<String, Encoding>? encoding,)?)

A variant of when that fallback to returning null

It is equivalent to doing:

switch (sealedClass) {
  case Subclass(:final field):
    return ...;
  case _:
    return null;
}

Implementation

@optionalTypeArgs TResult? whenOrNull<TResult extends Object?>(TResult? Function( Schema? schema,  dynamic example,  Map<String, Example>? examples,  Map<String, Encoding>? encoding)?  $default,) {final _that = this;
switch (_that) {
case _MediaType() when $default != null:
return $default(_that.schema,_that.example,_that.examples,_that.encoding);case _:
  return null;

}
}
