问题

组件不修改

  • 组件外包裹 StatefulBuilder
  • builder参数的值修改为 (context, setState) => Text()
  • 在需要修改的地方调用 setState((){})

static void receive() {
    RawDatagramSocket.bind(InternetAddress.anyIPv4, receiverPort)
        .then((RawDatagramSocket udpSocket) {
            udpSocket.broadcastEnabled = true;
            udpSocket.listen((e) {
                Datagram? dg = udpSocket.receive();
                if (dg != null) {
                    Log.info("received ${String.fromCharCodes(dg.data)}");
                }
            });
        });
}

go_router传参

其他和vue-router一样，还有个extra
