whenOrNull<TResult extends Object?> method

  1. @optionalTypeArgs
TResult? whenOrNull<TResult extends Object?>(
  1. TResult? $default(
    1. ServiceConfig? appview,
    2. ServiceConfig? pds,
    3. ServiceConfig? blobDivert,
    4. ServiceConfig? chat,
    5. ViewerConfig? viewer,
    6. String? verifierDid,
    7. Map<String, dynamic>? $unknown,
    )?
)

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(@ServiceConfigConverter()  ServiceConfig? appview, @ServiceConfigConverter()  ServiceConfig? pds, @ServiceConfigConverter()  ServiceConfig? blobDivert, @ServiceConfigConverter()  ServiceConfig? chat, @ViewerConfigConverter()  ViewerConfig? viewer,  String? verifierDid,  Map<String, dynamic>? $unknown)?  $default,) {final _that = this;
switch (_that) {
case _ServerGetConfigOutput() when $default != null:
return $default(_that.appview,_that.pds,_that.blobDivert,_that.chat,_that.viewer,_that.verifierDid,_that.$unknown);case _:
  return null;

}
