whenOrNull<TResult extends Object?> method

@optionalTypeArgs TResult? whenOrNull<TResult extends Object?>(TResult? $default(Sub2ApiAdminQuotaPlatform platform, Sub2ApiAdminQuotaWindow window)?)

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(
    Sub2ApiAdminQuotaPlatform platform,
    Sub2ApiAdminQuotaWindow window,
  )?
  $default,
) {
  final _that = this;
  switch (_that) {
    case _Sub2ApiAdminResetPlatformQuotaRequest() when $default != null:
      return $default(_that.platform, _that.window);
    case _:
      return null;
  }
}
