More languages: 简体中文-TUIKit介绍 简体中文-快速集成

TUIKit has Chat SDK, UI components and basic business logic inside. You can choose our pure Chat SDK tencent-cloud-chat-sdk if you tend to build the UI yourself.

Experience DEMO

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

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

Also, taking a look of the screenshots of TUIKit from here are suggested.

Introduction to TUIKit

TUIKit is a set of official UI components for Tencent Cloud Chat SDK, with chat business logic around it. It provides components such as the conversation, chat, relationship chain, and group.

You can use these UI components to build your APP with the In-APP chat module quickly and easily.

Currently, Flutter TUIKit contains the following main components:

• TIMUIKitCore: Core entry
• TIMUIKitConversation: Conversation list
• TIMUIKitChat: Chat module, includes historical message list and message sending area, with some other features like message reaction and URL preview, etc.
• TIMUIKitContact: Contacts list
• TIMUIKitProfile: User profile and relationship management
• TIMUIKitGroupProfile: Group profile and management
• TIMUIKitGroup: The list of group self joined
• TIMUIKitBlackList: The list of user been blocked
• TIMUIKitNewContact: New contacts application list
• TIMUIKitSearch: Search globally
• TIMUIKitSearchMsgDetail: Search in specific conversation

Also, there are some other useful components and widgets, that can help to build your APP, and meet your business needs, including group entry application list and group member list, etc.

For the source code of the project in the figure above, see im-flutter-uikit. The project is open source and can be used directly.

Supported Platforms

• Android
• iOS
• Web(After version of 0.1.4)

Get Started

Please refer this documents, for a completed and detailed get started guide.

Directions

The following guide describes how to use Flutter TUIKit to build a simple Chat APP quickly.

You may refer to the appendix, if willing to know about the detail and parameter for each widgets.

If you tend to add this Flutter TUIKit to your existing application directly, you may refer to this documentation. Add the Flutter module to your existing app, coding once and deploying to all platforms. It could reduce your workload, to adding chat and call modules to your existing, to a large extent.

Step 0. Create two accounts for testing

Signed up and log in to the Tencent IM console.

Create an application and enter in.

Select Auxiliary Tools > UserSig Generation and Verification on the left sidebar. Generate two pairs of "UserID" and the corresponding "UserSig", and copy the "key" information. Refer to here.

Tips: You may create "user1" and "user2" here.

Note：

The correct UserSig distribution method is to integrate the calculation code of UserSig into your 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 How do I calculate UserSig on the server?.

Step 1. Create a Flutter app and add permission configuration

Quickly create a Flutter APP by referring to Flutter documentation.

TUIKit needs the permissions of shooting/album/recording/network for basic messaging function. You need to declare in the permission manually to use the relevant capabilities normally.

Android

Open android/app/src/main/AndroidManifest.xml, add the following lines between <manifest> and </manifest>.

<uses-permission
    android:name="android.permission.INTERNET"/>
<uses-permission
    android:name="android.permission.RECORD_AUDIO"/>
<uses-permission
    android:name="android.permission.FOREGROUND_SERVICE"/>
<uses-permission
    android:name="android.permission.ACCESS_NETWORK_STATE"/>
<uses-permission
    android:name="android.permission.VIBRATE"/>
<uses-permission
    android:name="android.permission.ACCESS_BACKGROUND_LOCATION"/>
<uses-permission
    android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission
    android:name="android.permission.READ_EXTERNAL_STORAGE"/>
<uses-permission
    android:name="android.permission.CAMERA"/>

iOS

Open ios/Podfile, add the following lines to the end of the file.

post_install do |installer|
  installer.pods_project.targets.each do |target|
    flutter_additional_ios_build_settings(target)
    target.build_configurations.each do |config|
          config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] ||= [
            '$(inherited)',
            'PERMISSION_MICROPHONE=1',
            'PERMISSION_CAMERA=1',
            'PERMISSION_PHOTOS=1',
          ]
        end
  end
end

Step 2. Install dependencies

Add tencent_cloud_chat_uikit under dependencies in the pubspec.yaml file, or run the following command:

flutter pub add tencent_cloud_chat_uikit

It supports Android and iOS as default, if you are also willing to use it on the Web, please refer to the following guide.

Web Supports

Version of 0.1.4 or later are required for web supports.

If your existing Flutter project does not support Web, run flutter create . in the project root directory to add web support.

Install JS dependencies to web/ by npm or yarn.

cd web

npm init

npm i tim-js-sdk

npm i tim-upload-plugin

Open web/index.html , add the following two lines between <head> and </head> to import them.

<script src="./node_modules/tim-upload-plugin/index.js"></script>
<script src="./node_modules/tim-js-sdk/tim-js-friendship.js"></script>

Step 3. Initialize TUIKit

Initialize the TUIKit after you app starts.You only need to perform the initialization once for the project to start.

Get the instance of TUIKit first by TIMUIKitCore.getInstance(), followed by initializing it, init(), with your 'sdkAppID'.

/// main.dart
import 'package:tencent_cloud_chat_uikit/tencent_cloud_chat_uikit.dart';

final CoreServicesImpl _coreInstance = TIMUIKitCore.getInstance();
  @override
  void initState() {
    _coreInstance.init(
      sdkAppID: 0, // Replace 0 with the SDKAppID of your IM application
      loglevel: LogLevelEnum.V2TIM_LOG_DEBUG,
      listener: V2TimSDKListener());
    super.initState();
 }
}

You may also better to register a callback function for onTUIKitCallbackListener here, please refer to the appendix.

Step 4. Get the signature and log in

Now, you can log in one of the testing accounts, generated on Step 0, to start the IM module.

Log in by _coreInstance.login .

/// main.dart
import 'package:tencent_cloud_chat_uikit/tencent_cloud_chat_uikit.dart';

final CoreServicesImpl _coreInstance = TIMUIKitCore.getInstance();
_coreInstance.login(userID: userID, userSig: userSig);

Caveat: Importing UserSig to your application is ONLY for Debugging purposes and cannot be applied for the Release version. Before publishing your app, you should generate your UserSig from your server. Refers to: https://www.tencentcloud.com/document/product/1047/34385?from=pub

Step 5. Implementing the conversation list page

You can take the conversation (channel) list page as the homepage of your Chat module, covering the conversation with all users and groups that have chat records.

You can create a Conversation class, with TIMUIKitConversation on its body, to render the conversation list. The only parameter you need to provide at least is onTapItem callback, aimed at navigating to the Chat page for each conversation. The Chat class will be introduced in the next step.

import 'package:flutter/material.dart';
import 'package:tencent_cloud_chat_uikit/tencent_cloud_chat_uikit.dart';

class Conversation extends StatelessWidget {
  const Conversation({Key? key}) : super(key: key);
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: const Text(
          "Message",
          style: TextStyle(color: Colors.black),
        ),
      ),
      body: TIMUIKitConversation(
        onTapItem: (selectedConv) {
          Navigator.push(
              context,
              MaterialPageRoute(
                builder: (context) => Chat(
                  selectedConversation: selectedConv,
                ),
              ));
        },
      ),
    );
  }
}

Step 6. Implementing the chat page

The chat page is composed of the main historical message list and a message sending bar at the bottom.

You can create a Chat class, with TIMUIKitChat on its body, to render the chat page. It is recommended to provide a onTapAvatar callback function, for navigating to the profile page for current contact, which will be introduced in the next step.

import 'package:flutter/material.dart';
import 'package:tencent_cloud_chat_uikit/tencent_cloud_chat_uikit.dart';

class Chat extends StatelessWidget {
  final V2TimConversation selectedConversation;
  const Chat({Key? key, required this.selectedConversation}) : super(key: key);
  String? _getConvID() {
    return selectedConversation.type == 1
        ? selectedConversation.userID
        : selectedConversation.groupID;
  }
  @override
  Widget build(BuildContext context) {
    return TIMUIKitChat(
      conversationID: _getConvID() ?? '', // groupID or UserID
      conversationType: selectedConversation.type ?? 1, // Conversation type
      conversationShowName: selectedConversation.showName ?? "", // Conversation display name
      onTapAvatar: (_) {
            Navigator.push(
                context,
                MaterialPageRoute(
                 builder: (context) => UserProfile(userID: userID),
            ));
      }, // Callback for the clicking of the message sender profile photo. This callback can be used with `TIMUIKitProfile`.
    );
}

Step 7. Implementing the user profile page

This page can show the profile of a specific user and maintain the relationship between the current login user and it.

Here, you can create a UserProfile class, with TIMUIKitProfile on its body, to render the profile page.

The only parameter you have to provide at least is 'userID', while this component can generate the profile and relationship maintenance page based on the existence of friendship automatically.

TIPS

Please give priority to use profileWidgetBuilder, to customize some profile widgets, with profileWidgetsOrder, determine the vertical sequence, if you tend to customize this page. If this method could not meet your business needs, you may consider using builder instead.

import 'package:flutter/material.dart';
import 'package:tencent_cloud_chat_uikit/tencent_cloud_chat_uikit.dart';

class UserProfile extends StatelessWidget {
  final String userID;
  const UserProfile({required this.userID, Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
       title: const Text(
         "Message",
         style: TextStyle(color: Colors.black),
       ),
     ),
     body: TIMUIKitProfile(
          userID: widget.userID,
     ),
    );
  }
}

Now, your app can send/receive messages, show the conversation list, and deal with the contact friendship.

You can use others components from TUIKit continually to implement the complete Chat module quickly and easily.

FAQs

Do I need to integrate Chat SDK after integrating TUIKit?

No. You don't need to integrate Chat SDK again. If you want to use Chat SDK related APIs, you can get them via TIMUIKitCore.getSDKInstance(). This method is recommended to ensure Chat SDK version consistency.

Why did force quit occur when I sent voice, image, file or other messages?

Check whether you have enabled the camera, mic, album, or other related permissions.

Refers to Step 1 above.

What should I do if clicking Build And Run for an Android device triggers an error, stating no available device is found?

Check that the device is not occupied by other resources. Alternatively, click Build to generate an APK package, drag it to the simulator, and run it.

What should I do if an error occurs during the first run for an iOS device?

If an error occurs after the configuration, click Product > Clean Build Folder , clean the product, and run pod install or flutter run again.

What should I do if an error occurs during debugging on a real iOS device when I am wearing an Apple Watch?

Turn on Airplane Mode on your Apple Watch, and go to Settings > Bluetooth on your iPhone to turn off Bluetooth.

Restart Xcode (if opened) and run flutter run again.

Issue with Flutter environment?

If you want to check the Flutter environment, run flutter doctor to detect whether the Flutter environment is ready.

What should I do when an error occurs on an Android device after TUIKit is imported into the application automatically generated by Flutter?

1. Open android\app\src\main\AndroidManifest.xml and complete xmlns:tools="http://schemas.android.com/tools" / android:label="@string/android_label" / tools:replace="android:label" as follows.

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="Replace it with your Android package name"
    xmlns:tools="http://schemas.android.com/tools">
    <application
        android:label="@string/android_label"
        tools:replace="android:label"
        android:icon="@mipmap/ic_launcher" // Specify an icon path
        android:usesCleartextTraffic="true"
        android:requestLegacyExternalStorage="true">

2. Open android\app\build.gradle and complete minSdkVersion and targetSdkVersion in defaultConfig.

defaultConfig {
  applicationId "" // Replace it with your Android package name
  minSdkVersion 21
  targetSdkVersion 30
}

*/

onTUIKitCallbackListener

This listener is used to get information including: errors form SDK API / errors form Flutter / some remind information that may need to pop up to prompt users.

Determine the type by TIMCallbackType.

You may refer to our DEMO for the codes in this part, and modifying up to your business needs.

Errors form SDK API(TIMCallbackType.API_ERROR)

In this scenario, SDK API original errorMsg and errorCode are provided.

Error codes listed here

Errors form Flutter(TIMCallbackType.FLUTTER_ERROR)

This error is captured by listening Flutter natively throwing an exception, providing stackTrace (from FlutterError.onError) or catchError (from try-catch) when the error occurs.

Remind information(TIMCallbackType.INFO)

It is suggest to pup up to prompt users for this kind of messages.

Provide the infoCode info code to help you determine the current scene, and provide the default prompt recommendation infoRecommendText.

You can directly pop up our recommendations, or you can customize the recommendations according to the scene code. The language of recommendation text is adaptive according to the system language or the language you specified, do not judge the scene according to the recommendation language.

The rules for info code are as follows:

The info code consists of seven digits, the first five digits determine the components of the scene, and the last two digits determine the specific performance of the scene.

    onEnterConversation: (V2TimConversation conversation, String initKeyword){}, // Navigating to search in specific conversation. Please navigate to TIMUIKitSearchMsgDetail manually
);
