CodePudding user response：

below is how you show an alert dialog:

ListView _buildListViewOfDevices(context) { //pass context as parameter
      List<Container> containers = <Container>[];
      for (BluetoothDevice device in widget.devicesList) {
        if (device.name == 'Airbud Pro Plus') {
          showDialog(
              context: context,
              builder: (context) => AlertDialog(
                    title: Text('greetings!!'),
                    content: Text("you are using Apple Airbud Pro Plus"),
                  ));
        }
      }
    }

In case you are using rflutter_alert package:

function call example:

RaisedButton(
              child: Text('Basic Alert'),
              onPressed: () => _onBasicAlertPressed(context),
            ),

function body example:

_onBasicAlertPressed(context) {
    Alert(
            context: context,
            title: "RFLUTTER ALERT",
            desc: "Flutter is more awesome with RFlutter Alert.")
        .show();
  }
