如何在 Ffutter 中使用 Laravel Echo with Socket.io

Question

我正在开发一个 flutter 项目，该项目使用 Laravel 回显和 socket.io 在后端进行聊天。使用 Laravel echo 包在 Web 版本中实现起来非常容易，但我对 Flutter 使用什么来连接和监听事件一无所知。我需要帮助！

你可以关注this blog.

这里有两个简单的方法：

sendSingleChatMessage(ChatMessageModel chatMessageModel, User toChatUser) {
    print('Sending Message to: ${toChatUser.name}, ID: ${toChatUser.id}');
    if (null == _socket) {
      print("Socket is Null, Cannot send message");
      return;
    }
    _socket.emit("single_chat_message", [chatMessageModel.toJson()]);
}

setOnChatMessageReceivedListener(Function onChatMessageReceived) {
    _socket.on(ON_MESSAGE_RECEIVED, (data) {
      print("Received $data");
      onChatMessageReceived(data);
    });
}

中还有另一个包要使用

// Create echo instance
Echo echo = new Echo({
  'broadcaster': 'socket.io',
  'client': IO.io,
});

// Listening public channel
echo.channel('public-channel').listen('PublicEvent', (e) {
  print(e);
});

// Listening private channel
// Needs auth. See details how to authorize channel below in guides
echo.private('private-channel').listen('PrivateEvent', (e) {
  print(e);
});

// Listening presence channel
// Needs auth. See details how to authorize channel below in guides
echo.join('presence-channel')
  .here((users) {
    print(users);
  }).joining((user) {
    print(user);
  }).leaving((user) {
    print(user);
  }).listen('PresenceEvent', (e) {
    print(e);
  });

// Accessing socket instance
echo.socket.on('connect', (_) => print('connected'));
echo.socket.on('disconnect', (_) => print('disconnected'));
