dart-sdk's Introduction

Tinode Dart SDK

This SDK implements Tinode client-side protocol for multi platform applications based on dart. This is not a standalone project. It can only be used in conjunction with the Tinode server. You can find released packages and versions on pub page.

Installation

Depend on it

Run this command for dart applications:

dart pub add tinode

Run this command for flutter applications:

flutter pub add tinode

Import it

Now in your Dart code, you can use:

import 'package:tinode/tinode.dart';

Getting support

Read server-side API documentation to know about packets.
A complete documentation will be created soon.
You can see a simple example in ./example directory.
For bugs and feature requests open an issue

Platform support

dart-sdk's Issues

Is there any date/time variable in the chat to place them in order?

onPres can not will be triggered when a `pres` message is received

lib/src/models/server-messages.dart

static PresMessage fromMessage(Map<String, dynamic> msg) {
    return PresMessage(
      topic: msg['msg'],
      src: msg['src'],
      what: msg['what'],
      seq: msg['seq'],
      clear: msg['clear'],
      delseq:
          msg['delseq'] != null && msg['delseq'].length != null ? msg['delseq'].map((seq) => DeleteTransactionRange.fromMessage(seq)).toList() : [],
      ua: msg['ua'],
      act: msg['act'],
      tgt: msg['tgt'],
      acs: msg['acs'] != null ? AccessMode(msg['acs']) : null,
      dacs: msg['dacs'] != null ? AccessMode(msg['dacs']) : null,
    );
  }
}

需要改为

static PresMessage fromMessage(Map<String, dynamic> msg) {
    return PresMessage(
      topic: msg['topic'],
      src: msg['src'],
      what: msg['what'],
      seq: msg['seq'],
      clear: msg['clear'],
      delseq:
          msg['delseq'] != null && msg['delseq'].length != null ? msg['delseq'].map((seq) => DeleteTransactionRange.fromMessage(seq)).toList() : [],
      ua: msg['ua'],
      act: msg['act'],
      tgt: msg['tgt'],
      acs: msg['acs'] != null ? AccessMode(msg['acs']) : null,
      dacs: msg['dacs'] != null ? AccessMode(msg['dacs']) : null,
    );
  }
}

否则

grp!.onPres.listen

无法获取到最新的数据

Can I create a new Topic and add new members to it?

First create a new group, then add new members to it

[Error] _Exception (Exception: topic not found (404))

How to get chatId/GroupId dynamic?\

How to know who send message to me?

In the flutter project, I copy example code to test

tinode = Tinode('Moein', ConnectionOptions(apiKey: key, host: host, secure: false), false);
await tinode.connect();
await tinode.loginBasic('alice', 'alice123', null);
var me = tinode.getMeTopic();
  me.onSubsUpdated.listen((value) {
    for (var item in value) {
      print('Subscription update: ' + item.public.toString() +  ' - Unread Messages:' + item.unread.toString());
    }
  });
  me.onContactUpdate.listen((value) {
    print('Contact Update: ' + value.toString());
  });
  me.onPres.listen((value) {
    print("Me Receive Pres message:" + value.toString());
  });
  // me.onAllMessagesReceived.listen((value) {
  //   print("All message receive:" + value.toString());
  // });
  // me.onInfo.listen((value) {
  //   print("Info event:" + value.toString());
  // });
  // me.onMetaSub.listen((value) {
  //   print("meta sub event:" + value.toString());
  // });
  await me.subscribe(MetaGetBuilder(me).withLaterSub(null).build(), null);
  
  var grp = tinode.getTopic('grpT9wlZYxma0Q');
  grp.onData.listen((value) {
    if (value != null) {
      print('DataMessage: ' + value.content);
    }
  });
  await grp.subscribe(MetaGetBuilder(grp).withLaterSub(null).withLaterData(null).build(), null);
  var msg = grp.createMessage('This is cool', true);
  await grp.publishMessage(msg);

When I login in by another account, and send a message to the group. I can see log: DataMessage: xxxx
But can't see any log If sending a message to the user "alice" directly.

what event should be bind to get who sends a message and what's the message content?
Are there any plan to explain dart sdk?

How to get user/groups imageUrl on the All Chat part?

How to use the library?

After login, I cannot figure out how to do these things:

Get list of topic
Find other user
Get list message of topic
Listen to the incoming message of topic.
Listen to the typing message.

Can you add more examples for these?

Explain method _updateDeletedRanges()

Trying to understand this method but have no clue.
Could you explain the purpose of the method?

  /// Calculate ranges of missing messages
  void _updateDeletedRanges() {
    var ranges = <DataMessage>[];
    DataMessage prev;

    // Check for gap in the beginning, before the first message.
    var first = _messages.length > 0 ? _messages.getAt(0) : null;

    if (first != null && _minSeq > 1 && !_noEarlierMsgs) {
      // Some messages are missing in the beginning.
      if (first.hi != null && (first.hi ?? 0) > 0) {
        // The first message already represents a gap.
        if ((first.seq ?? 0) > 1) {
          first.seq = 1;
        }
        if ((first.hi ?? 0) < _minSeq - 1) {
          first.hi = _minSeq - 1;
        }
        prev = first;
      } else {
        // Create new gap.
        prev = DataMessage(seq: 1, hi: _minSeq - 1);
        ranges.add(prev);
      }
    } else {
      // No gap in the beginning.
      prev = DataMessage(seq: 0, hi: 0);
    }

    // Find gaps in the list of received messages. The list contains messages-proper as well
    // as placeholders for deleted ranges.
    // The messages are iterated by seq ID in ascending order.
    _messages.forEach((data, i) {
      // Do not create a gap between the last sent message and the first unsent.
      if (data.seq! >= _configService.appSettings.localSeqId) {
        return;
      }

      // New message is reducing the existing gap
      if (data.seq == ((prev.hi != null && prev.hi! > 0) ? prev.hi : prev.seq)! + 1) {
        // No new gap. Replace previous with current.
        prev = data;
        return;
      }

      // Found a new gap.
      if (prev.hi != null && prev.hi != 0) {
        // Previous is also a gap, alter it.
        prev.hi = data.hi! > 0 ? data.hi : data.seq;
        return;
      }

      // Previous is not a gap. Create a new gap.
      prev = DataMessage(
        seq: (data.hi! > 0 ? data.hi! : data.seq)! + 1,
        hi: data.hi! > 0 ? data.hi : data.seq,
      );
      ranges.add(prev);
    }, null, null);

    // Check for missing messages at the end.
    // All messages could be missing or it could be a new topic with no messages.
    var last = _messages.length > 0 ? _messages.getLast() : null;
    var maxSeq = max(seq!, _maxSeq);
    if ((maxSeq > 0 && last == null) || (last != null && (((last.hi != null && last.hi! > 0) ? last.hi : last.seq)! < maxSeq))) {
      if (last != null && (last.hi != null && last.hi! > 0)) {
        // Extend existing gap
        last.hi = maxSeq;
      } else {
        // Create new gap.
        ranges.add(DataMessage(seq: last != null ? last.seq! + 1 : 1, hi: maxSeq));
      }
    }

    // Insert new gaps into cache.
    ranges.map((gap) {
      _messages.put([gap]);
    });
  }

While getting the chat of a specific group/user how to differenciate the Messages i.e sender or reciever?

How to send pictures or files ？

I didn't find the corresponding function in the source code。By the way, when will the documentation be complete?

How can set the message head data?

I want to send a Drafty type message, such as Image via SDK, but cannot find where to set it

Tinode Connect and Disconnect Issue

Hi, I'm coming again.
I initialized the Tincode as below codes on app startup:

if (tinode == null){
        tinode = Tinode(
            'Wow',
            ConnectionOptions(WebSocketUtils.WsUrl, WebSocketUtils.ApiKey, secure: true),
            ApiConstant.isDebug);
}
 
CtrlMessage connectResult = await tinode.connect();
if (connectResult.code < 300) {
  isConnect = true;
}

When the user logout, call the disconnect method and set the tinode instance to null:

disConnect() {
    tinode.disconnect();
    tinode = null;
}

But after the user signs in again, I re-call the initialization method, it throws the error:

Invalid argument(s): Object/factory with  type ConfigService is already registered inside GetIt. 
      throwIf (package:get_it/get_it_impl.dart:7:18)
#1      _GetItImplementation._register (package:get_it/get_it_impl.dart:800:5)
#2      _GetItImplementation.registerSingleton (package:get_it/get_it_impl.dart:585:5)
#3      Tinode._registerDependencies (package:tinode/tinode.dart:123:13)
#4      new Tinode (package:tinode/tinode.dart:114:5)
#5      WebSocketUtils.connectService (package:wow/pages/home/messages/websocket_utils.dart:37:18)
#6      WebSocketUtils.login (package:wow/pages/home/messages/websocket_utils.dart:54:13)
<asynchronous suspension>

I'm not sure what's problem is, is my disconnect not correct?
Thanks

Call setMeta error

I want to update my profile as below code:

var _public = new Map();
_public.putIfAbsent("fn", () => _myProfile.nickName);
_public.putIfAbsent("photo", () => _myProfile.avatar);
_public.putIfAbsent("gender", () => _myProfile.gender);

var me = await WebSocketUtils.getInstance().tinode.getMeTopic();
me.setMeta(new SetParams(desc: new TopicDescription(public: _public))).then((value) {
LogUtil.v(value);
return value;
}, onError: (error) {
LogUtil.e(error);
return null;
});

But throw the error:
Converting object to an encodable object failed: Instance of 'TopicDescription'
cause: NoSuchMethodError: Class 'TopicDescription' has no instance method 'toJson'.
