Tencent Cloud Chat SDK

Globally interconnected In-App Chat, user profile and relationship chains and offline push.

This pure Chat SDK do not contain UI components, you can choose our UI and business logic library tim_ui_kit if you tend to integrate quickly.

Experience DEMO

You can experience our Chat and Voice/Video Call modules via the following demo apps.

Those versions of demo has been build by the same Flutter project with our SDKs and extensions.

Mobile APP	WEB - H5
[Recommend] iOS/Android APP	Scan for the Web DEMO

Environment Requirements

	Version
Flutter	Flutter 2.2.0 or later for the Chat SDK; Flutter 2.10.0 or later for the TUIKit integration component library.
Android	Android Studio 3.5 or later; devices with Android 4.1 or later for apps
iOS	Xcode 11.0 or later. Ensure that your project has a valid developer signature.

Supported Platforms

We are aiming to build a Chat SDK and TUIKit that supports all platforms of Flutter, helping you to develop once and deploy it on all platforms.

Platform	non-UI Chat SDK (this package)	UI components library (TUIKit)
iOS	Supports	Supports
Android	Supports	Supports
Web	Supports since 4.1.1+2 version	Supports since 0.1.5 version
macOS	Supports since 4.1.9 version	Coming soon
Windows	Supports since 4.1.9 version	Coming soon

Some extra steps are needed for Web/macOS/Windows, you can refer to "Flutter for Web support" and "Flutter for Desktop support" in this tutorial.

Preparation

You have signed up for a Tencent Cloud account and completed identity verification.
You have created an application as instructed in Creating and Upgrading an Application and recorded the SDKAppID.

Part 1. Creating a Test Account

In the IM console, select your application and click Auxiliary Tools > UserSig Generation & Verification on the left sidebar. Create two UserID and their corresponding UserSig, and copy the UserID, Key, and UserSig for subsequent logins.

? The account is for development and testing only. Before the application release, the correct UserSig distribution method is to generate UserSig on the server and provide an application-oriented API. When UserSig is needed, your application can send a request to the business server for a dynamic UserSig. For more information, see Generating UserSig.

Part 2. Selecting a Proper Scheme to Integrate the SDK for Flutter

Tencent Cloud Chat offers three integration schemes:

	Use Case
Using the demo	Our demo is a complete chat application with open-source code. If you need to implement chat scenarios, you can use the demo for secondary development. Try it out here.
Using UI library	The Chat UI components library TUIKit provides common UI components, such as conversation list, chat page, and contact list. You can use those components to build an In-APP chat module to your Flutter APP quickly. This solution is recommended.
Self-implementing with this package	Use this solution if TUIKit cannot meet your needs.

To better understand Chat SDK APIs, see API examples here, which shows how to call APIs and trigger listeners.

Part 3. Using the Demo

Running the demo

Download the source code and install dependencies:

# Clone the code
git clone https://github.com/TencentCloud/TIMSDK.git

# Enter the demo directory of Flutter
cd TIMSDK/Flutter/Demo/im-flutter-uikit

# Install dependencies
flutter pub get

Run the demo:

# Start the demo. Replace `SDK_APPID` and `KEY`
flutter run --dart-define=SDK_APPID={YOUR_SDKAPPID} --dart-define=ISPRODUCT_ENV=false --dart-define=KEY={YOUR_KEY}

--dart-define=SDK_APPID={YOUR_SDKAPPID}. Here, {YOUR_SDKAPPID} needs to be replaced with the SDKAppID of your application.

--dart-define=ISPRODUCT_ENV=false. Set it to false for a development environment.

--dart-define=KEY={YOUR_KEY}. Here, {YOUR_KEY} needs to be replaced with the Key recorded in Part 1. Creating a Test User.

Demo code structure

The TUIKit for Flutter is used for build the UI and business logic of the demo. The demo layer itself is only used to build the application, process navigation redirects, and call instantiated TUIKit components.

Folder	Description
lib	Core application directory
lib/i18n	Internationalization code, excluding the internationalization capabilities and strings of TUIKit, which can be imported as needed.
lib/src	Main application directory
lib/src/pages	Important navigation pages of the demo. After the application is initialized, `app.dart` displays the loading animation, judges the login status, and redirects the user to `login.dart` or `home_page.dart`. After the user logs in, the login information will be stored locally through the `shared_preference` plugin and used for automatic login upon future application launch. If there is no such information or the login fails, the user will be redirected to the login page. During automatic login, the user is still on `app.dart` and can see the loading animation. `home_page.dart` has a bottom tab to switch between the four main feature pages of the demo.
lib/utils	Some tool function classes.

Basically, a TUIKit component is imported into each dart file in lib/src. After the component is instantiated in the file, the page can be rendered.

Below are main files:

Main File in `lib/src`	Description
add_friend.dart	Friend request page that uses the `TIMUIKitAddFriend` component.
add_group.dart	Group joining request page that uses the `TIMUIKitAddGroup` component.
blacklist.dart	Blocklist page that uses the `TIMUIKitBlackList` component.
chat.dart	Main chat page that uses all the chat capabilities of TUIKit and the `TIMUIKitChat` component.
chatv2.dart	Main chat page that uses atomic capabilities and the `TIMUIKitChat` component.
contact.dart	Contacts page that uses the `TIMUIKitContact` component.
conversation.dart	Conversation list page that uses the `TIMUIKitConversation` component.
create_group.dart	Group chat page that is implemented in the demo with no component used.
group_application_list.dart	Group application list page that uses the `TIMUIKitGroupApplicationList` component.
group_list.dart	Group list page that uses the `TIMUIKitGroup` component.
group_profile.dart	Group profile and management page that uses the `TIMUIKitGroupProfile` component.
newContact.dart	New contact request page that uses the `TIMUIKitNewContact` component.
routes.dart	Demo route that navigates users to the login page `login.dart` or homepage `home_page.dart`.
search.dart	Global search and in-conversation search page that uses the `TIMUIKitSearch` (global search) and `TIMUIKitSearchMsgDetail` (in-conversation search) components.
user_profile.dart	User information and relationship chain maintenance page that uses the `TIMUIKitProfile` component.

You can modify the above demo for secondary development or implement your business needs based on it.

Part 4. Using TUIKit Component Library to implement In-App Chat module in Half a Day

TUIKit is a UI components library for Tencent Cloud Chat SDK. It provides common UI components, such as conversation list, chat page, and contact list.

It's suggested to use those components to build an In-APP chat module to your Flutter APP quickly.

For more details and tutorial, see TUIKit Quick Integration and get started.

Part 5. Self-Implementing Integration with this Chat SDK

Prerequisites

You have created a Flutter application or have an application that can be based on Flutter.

Directions

Installing the Chat SDK

For detailed directions involved in this section, see SDK Integration (Flutter).

Run the following command to install the latest Chat SDK for Flutter.

Run the following command:

flutter pub add tencent_im_sdk_plugin

Some extra steps are needed for Web/macOS/Windows, you can refer to "Flutter for Web support" and "Flutter for Desktop support" in this tutorial.

Initializing the SDK

For detailed directions involved in this section, see here.

Call initSDK to initialize the SDK.

Pass in your sdkAppID.

import 'package:tencent_cloud_chat_sdk/enum/V2TimSDKListener.dart';
import 'package:tencent_cloud_chat_sdk/enum/log_level_enum.dart';
import 'package:tencent_cloud_chat_sdk/tencent_im_sdk_plugin.dart';
    TencentImSDKPlugin.v2TIMManager.initSDK(
    sdkAppID: 0, // Replace `0` with the `SDKAppID` of your IM application during integration
    loglevel: LogLevelEnum.V2TIM_LOG_DEBUG, // Log
    listener: V2TimSDKListener(),
  );

In this step, you can mount some listeners to the Chat SDK, mainly including those for network status and user information change. For more information, see V2TimSDKListener class.

Logging in with the test account

For detailed directions involved in this section, see Flutter.

Complete login verification using the test account created at the beginning.

Call the TencentImSDKPlugin.v2TIMManager.login method to log in with the test account.

If the returned res.code is 0, the login is successful.

import 'package:tencent_cloud_chat_sdk/tencent_im_sdk_plugin.dart';
 V2TimCallback res = await TencentImSDKPlugin.v2TIMManager.login (
    userID: userID,
    userSig: userSig, 
  );

? The account is for development and testing only. Before the application release, the correct UserSig distribution method is to integrate the UserSig calculation code into the server and provide an application-oriented API. When UserSig is needed, your application can send a request to the business server for a dynamic UserSig. For more information, see Generating UserSig.

Sending a message

For detailed directions involved in this section, see here.

The following shows how to send a text message:

Call createTextMessage(String) to create a text message.
Get the message ID from the returned value.
Call sendMessage() to send the message with the ID. receiver can be the ID of the other test account created earlier. groupID doesn't need to be entered for sending one-to-one messages.

Sample code:

import 'package:tencent_cloud_chat_sdk/tencent_im_sdk_plugin.dart';

V2TimValueCallback<V2TimMsgCreateInfoResult> createMessage =
      await TencentImSDKPlugin.v2TIMManager
          .getMessageManager()
          .createTextMessage(text: "The text to create");
          
String id = createMessage.data!.id!; // The message creation ID 

V2TimValueCallback<V2TimMessage> res = await TencentImSDKPlugin.v2TIMManager
      .getMessageManager()
      .sendMessage(
          id: id, // Pass in the message creation ID to
          receiver: "The userID of the destination user",
          groupID: "The groupID of the destination group",
          );

If sending failed, it may be that your sdkAppID doesn't support sending messages to strangers. In this case, enable the feature in the console for test.

Disable the friend relationship chain check here .

Getting the conversation list

For detailed directions involved in this section, see here.

After sending the test message in the previous step, log in with the other test account to load the conversation list.

There are two methods to load the conversation list:

Listen on the persistent connection callback to update the conversation list in real time.
Send a request through an API to get the paginated conversation list at one time.

Common use cases:

Get the conversation list upon application launch and listen on the persistent connection to update the conversation list in real time.

Requesting the conversation list at one time

To get the conversation list, you need to maintain nextSeq and record its current position.

import 'package:tencent_cloud_chat_sdk/tencent_im_sdk_plugin.dart';

String nextSeq = "0";

getConversationList() async {
  V2TimValueCallback<V2TimConversationResult> res = await TencentImSDKPlugin
      .v2TIMManager
      .getConversationManager()
      .getConversationList(nextSeq: nextSeq, count: 10);
  
  nextSeq = res.data?.nextSeq ?? "0";
}

At this point, you can see the message sent by the other test account in the previous step.

Listening on the persistent connection to get the real-time conversation list

Mount listeners to the SDK, process the callback event, and update the UI.

Mount listeners.

await TencentImSDKPlugin.v2TIMManager
      .getConversationManager()
      .setConversationListener(
        listener: new V2TimConversationListener(
          onConversationChanged: (List<V2TimConversation> list){
            _onConversationListChanged(list);
    },
          onNewConversation:(List<V2TimConversation> list){
            _onConversationListChanged(list);
    },

Process the callback event to display the latest conversation list on the UI.

import 'package:tencent_cloud_chat_sdk/tencent_im_sdk_plugin.dart';

List<V2TimConversation> _conversationList = [];

_onConversationListChanged(List<V2TimConversation> list) {
  for (int element = 0; element < list.length; element++) {
    int index = _conversationList.indexWhere(
        (item) => item!.conversationID == list[element].conversationID);
    if (index > -1) {
      _conversationList.setAll(index, [list[element]]);
    } else {
      _conversationList.add(list[element]);
    }
  }

Receiving a message

For detailed directions involved in this section, see here.

There are two methods to receive messages in the Chat SDK for Flutter:

Listen on the persistent connection callback to get message changes and update and render the historical message list in real time.
Send a request through an API to get paginated message history at one time.

Common use cases:

When entering a new conversation, request a certain number of historical messages at one time to display the historical message list.
Listen on the persistent connection to receive messages in real time and add them to the historical message list.

Requesting the historical message list at one time

We recommend you limit the number of messages loaded per page to 20 to avoid affecting the speed.

Dynamically record the current number of pages for the next request.

The sample code is as follows:

import 'package:tencent_cloud_chat_sdk/tencent_im_sdk_plugin.dart';

  V2TimValueCallback<List<V2TimMessage>> res = await TencentImSDKPlugin
      .v2TIMManager
      .getMessageManager()
      .getGroupHistoryMessageList(
        groupID: "groupID",
        count: 20,
        lastMsgID: "",
      );
      
  List<V2TimMessage> msgList = res.data ?? [];
  
  // here you can use msgList to render your message list
    }

Listening on the persistent connection to get new messages in real time

After the historical message list is initialized, new messages are from the persistent connection V2TimAdvancedMsgListener.onRecvNewMessage.

After the onRecvNewMessage callback is triggered, add new messages to the historical message list as needed.

Below is the sample code for binding a listener:

import 'package:tencent_cloud_chat_sdk/tencent_im_sdk_plugin.dart';

final adVancesMsgListener = V2TimAdvancedMsgListener(
onRecvNewMessage: (V2TimMessage newMsg) {
  _onReceiveNewMsg(newMsg);
},
/// ... other listeners related to message
);

TencentImSDKPlugin.v2TIMManager
    .getMessageManager()
    .addAdvancedMsgListener(listener: adVancesMsgListener);

At this point, you have completed the Chat module development. You can send and receive messages and enter different conversations.

You can develop more features, such as group, user profile, relationship chain, offline push, and local search.
