whenOrNull<TResult extends Object?> method

  1. @optionalTypeArgs
TResult? whenOrNull<TResult extends Object?>(
  1. TResult? $default(
    1. String serviceDid,
    2. String token,
    3. NotificationRegisterPushPlatform platform,
    4. String appId,
    5. bool? ageRestricted,
    6. 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( String serviceDid,  String token, @NotificationRegisterPushPlatformConverter()  NotificationRegisterPushPlatform platform,  String appId,  bool? ageRestricted,  Map<String, dynamic>? $unknown)?  $default,) {final _that = this;
switch (_that) {
case _NotificationRegisterPushInput() when $default != null:
return $default(_that.serviceDid,_that.token,_that.platform,_that.appId,_that.ageRestricted,_that.$unknown);case _:
  return null;

}
}
