whenOrNull<TResult extends Object?> method

@optionalTypeArgs TResult? whenOrNull<TResult extends Object?>(TResult? $default(String crv, bool ext, List<String> keyOps, String kty, String x, String y,)?)

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(@JsonKey(name: 'crv')  String crv, @JsonKey(name: 'ext')  bool ext, @JsonKey(name: 'key_ops')  List<String> keyOps, @JsonKey(name: 'kty')  String kty, @JsonKey(name: 'x')  String x, @JsonKey(name: 'y')  String y)?  $default,) {final _that = this;
switch (_that) {
case _PublicKey() when $default != null:
return $default(_that.crv,_that.ext,_that.keyOps,_that.kty,_that.x,_that.y);case _:
  return null;

}
}
