setLocalCustomData method Null safety
Set message custom data (saved locally, will not be sent to the opposite end, and will be invalid after the program is uninstalled and reinstalled) localCustomData is just transparent transmission Note: web does not support this interface
Implementation
Future<V2TimCallback> setLocalCustomData({
required String msgID,
required String localCustomData,
}) async {
return ImFlutterPlatform.instance
.setLocalCustomData(msgID: msgID, localCustomData: localCustomData);
}
