whenOrNull<TResult extends Object?> method

@optionalTypeArgs TResult? whenOrNull<TResult extends Object?>(TResult? $default(String baseUrl, String? apiKey, String? projectId, String? appId, String sdkName, String sdkVersion, String sdkPlatform, String bundleId, String? clientId,)?)

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 baseUrl,  String? apiKey,  String? projectId,  String? appId,  String sdkName,  String sdkVersion,  String sdkPlatform,  String bundleId,  String? clientId)?  $default,) {final _that = this;
switch (_that) {
case _SdkConfig() when $default != null:
return $default(_that.baseUrl,_that.apiKey,_that.projectId,_that.appId,_that.sdkName,_that.sdkVersion,_that.sdkPlatform,_that.bundleId,_that.clientId);case _:
  return null;

}
}
