  if (returnValue is int) {
    print("isAddToApp=$returnValue type=${returnValue.runtimeType} objc should be return @(YES) not @(true)");
    return Future.value(returnValue == 1);
  } else if (returnValue is bool) {
    return Future.value(returnValue);
  } else {
    print("isAddToApp=$returnValue type=${returnValue.runtimeType} objc should be return @(YES) not @(true)");
