错误:调试VM时应将`SILENT_OBSERVATORY`设置为true

Question

我正在创建聊天，这是我得到的错误：

警告:在调试VM时，您应该将SILENT_OBSERVATORY设置为true，因为默认情况下，它将输出观察站URL。这破坏了各种记者合同。要设置该值，请定义DART_VM_OPTIONS=-DSILENT_OBSERVATORY=true。

我没有改变widget_test.dart中的任何东西，但当我启动应用程序时，它看起来是这样的：

完整的代码在这里：

void main() async {

 final client = Client(
    'b67pax5b2wdq',
    logLevel: Level.INFO,
  );

  await client.setUser(
    User(id: 'falling-mountain-7'),
    'eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJ1c2VyX2lkIjoiZmFsbGluZy1tb3VudGFpbi03In0.AKgRXHMQQMz6vJAKszXdY8zMFfsAgkoUeZHlI-Szz9E',
    
  );

  runApp(MaterialApp(home: Chat(client)));


class Chat extends StatelessWidget {
  final Client client;

  Chat(this.client);

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Container(

          limit: 20,
        ),
        channelWidget: ChannelPage(),
