whenOrNull<TResult extends Object?> method

@optionalTypeArgs TResult? whenOrNull<TResult extends Object?>(TResult? $default(String origin, String id, bool? isScam, int expiration, bool isVerified,)?)

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: 'origin')  String origin, @JsonKey(name: 'id')  String id, @JsonKey(name: 'isScam')  bool? isScam, @JsonKey(name: 'exp')  int expiration, @JsonKey(name: 'isVerified')  bool isVerified)?  $default,) {final _that = this;
switch (_that) {
case _VerifyClaims() when $default != null:
return $default(_that.origin,_that.id,_that.isScam,_that.expiration,_that.isVerified);case _:
  return null;

}
}
