  您可以使用以下插件来检查连接

  https://github.com/flutter/plugins/tree/master/packages/connectivity

  import 'package:connectivity/connectivity.dart';
  
    var connectivityResult = await (new 
    Connectivity().checkConnectivity());
  if (connectivityResult == ConnectivityResult.mobile) {
    // I am connected to a mobile network.
    }.  else if (connectivityResult == ConnectivityResult.wifi) 
  {
     // I am connected to a wifi network.
   }

  您可以使用 StreamBuilder 和 connectivity 插件构建反应式布局：

  StreamBuilder(
    stream: Connectivity().onConnectivityChanged,
    builder: (BuildContext context, AsyncSnapshot<ConnectivityResult> result) {
      if (result.data == ConnectivityResult.wifi)
        return Text('wifi');
      return Text('no wifi');
    }
  )
