TUIRoomKit supports Windows, Mac, Android, iOS, Flutter, Web, Electron and other development platforms.

Features #

• Easy access: Provide open source components with UI, save 90% development time, fast online video conference function.
• Platform connectivity: TUIRoomKit components of all platforms are interconnected and accessible.
• Screen sharing: Based on the screen acquisition capability of each platform jointly polished by 3000+ market applications, with exclusive AI coding algorithm, lower bit rate and clearer picture.
• Member management: It supports multiple standard room management functions such as all mute, single member gag, drawing, inviting to speak, kicking out of the room, etc.
• Other features: Support room members chat screen, sound Settings and other features, welcome to use.

Make a first video Conference #

Here is an example of integration with UI (ie TUIRoomKit), which is also our recommended integration method. The key steps are as follows:

Environment preparation #

Active the service #

You can follow the steps below to activate the TRTC Conference product service and receive a free 14-day trial version.

Note：

If you wish to purchase the paid version, please refer to TRTC Conference Monthly Packages, follow the Purchasing Guide to complete the purchase.

1. Visit TRTC Console > Applications, select Create application.

   

2. In the Create application pop-up, select Conference and enter the application name, click Create.

   

3. After completing the application creation, you will default entry to the application details page, select the Free Trail in the floating window, and click to** Get started for free**.

   

4. After the activation is completed, you can view the edition information on the current page. The SDKAppID and SDKSecretKey here will be used in the integration guide.

   

Access and use #

• Step 1: Add the dependency

  Add the rtc_conference_tui_kit plugin dependency in pubspec.yaml file in your project.

  dependencies:  
   rtc_conference_tui_kit: latest release version
  

  Execute the following command to install the plugin.

  flutter pub get
  

• Step 2: Complete Project Configuration

  • Since the rtc_conference_tui_kit has utilized the relevant features of the GetX state management library,, you need to use GetMaterialApp instead of MaterialApp in your application. Or you can set the navigatorKey property in your MaterialApp to Get.key to achieve the same effect.

  • Use Xcode to open your project, select [Project] -> [Building Settings] -> [Deployment], and set the [Strip Style] to Non-Global Symbols to retain all global symbol information.

  • To use the audio and video functions on iOS, you need to authorize the use of the mic and camera (For Android, the relevant permissions have been declared in the SDK, so you do not need to manually configure them).

    Add the following two items to the Info.plist of the App, which correspond to the prompt messages of the mic and camera when the system pops up the authorization dialog box.

    <key>NSCameraUsageDescription</key>
    <string>TUIRoom needs access to your Camera permission</string>
    <key>NSMicrophoneUsageDescription</key>
    <string>TUIRoom needs access to your Mic permission</string>
    

    After completing the above additions, add the following preprocessor definitions in your ios/Podfile to enable camera and microphone permissions.

    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',
          ]
        end
      end
    end
    

• Step 3: Login rtc_conference_tui_kit plugin

  Add the following code to your project, which serves to log in to the component by calling the relevant APIs in TUIRoomKit. This step is extremely critical, as only after logging in can you use the various functions of TUIRoomKit, so please be patient and check if the relevant parameters are configured correctly:

  import 'package:rtc_room_engine/rtc_room_engine.dart';
  
  var result = await TUIRoomEngine.login(
  SDKAPPID, // Please replace with your SDKAPPID
  'userId', // Please replace with your user ID
  'userSig',// Please replace with your userSig
  );
  
  if (result.code == TUIError.success) {
    // login success
  } else {
    // login error
  }
  

Parameter Description

Here is a detailed introduction to the key parameters used in the login function:

• SDKAppID：Obtained it in Active the service.

• UserID：The ID of the current user, which is a string that can only contain English letters (a-z and A-Z), numbers (0-9), hyphens (-), and underscores (_).

• UserSig：The authentication credential used by Tencent Cloud to verify whether the current user is allowed to use the TRTC service. You can get it by using the SDKSecretKey to encrypt information such as SDKAppID and UserID. You can generate a temporary UserSig on the UserSig Tools page in the TRTC console.

• For more information, please refer to the UserSig.

Note:

• Many developers have contacted us with questions regarding this step. Below are some of the frequently encountered problems:
  • The SDKAppID is set incorrectly.
  • UserSig is set to the value of SDKSecretKey mistakenly. The UserSig is generated by using the SDKSecretKey for the purpose of encrypting information such as SDKAppID, UserID, and the expiration time. But the value of the UserSig cannot be directly substituted with the value of the SDKSecretKey.
  • The UserID is set to a simple string such as 1, 123, or 111, and your colleague may be using the same UserID while working on a project simultaneously. In this case, login will fail as TUIRoomKit doesn't support login on multiple terminals with the same UserID. Therefore, we recommend you use some distinguishable UserID values during debugging.
• The sample code on GitHub uses the genTestUserSig function to calculate UserSig locally, so as to help you complete the current integration process more quickly. However, this scheme exposes your SDKSecretKey in the application code, which makes it difficult for you to upgrade and protect your SDKSecretKey subsequently. Therefore, we strongly recommend you run the UserSig calculation logic on the server and make the application request the UserSig calculated in real time every time the application uses the TUIRoomKit component from the server.

• Step 4: User rtc_conference_tui_kit plugin

  • Set self username and profile photo (optional)

    import 'package:rtc_room_engine/rtc_room_engine.dart';
    
    TUIRoomEngine.setSelfInfo(userName, avatarURL);
    

  • Start a quick conference

    import 'package:rtc_conference_tui_kit/rtc_conference_tui_kit.dart';
    
    ConferenceSession.newInstance('your roomId') 
      ..onActionSuccess = _quickStartSuccess
      ..onActionError = _quickStartError
      ..quickStart();
    
    void _quickStartSuccess() {
      //You can navigate to the conference page on your own in this success callback of starting a quick conference.
      Navigator.push(
        context,
        MaterialPageRoute(
          builder: (context) => ConferenceMainPage(),
        ),
      );
    }
    
    void _quickStartError(ConferenceError error, String message) {
      debugPrint("code: $error message: $message");
    }
    

  • Join a conference

    import 'package:rtc_conference_tui_kit/rtc_conference_tui_kit.dart';
    
    ConferenceSession.newInstance('your roomId') 
      ..onActionSuccess = _joinSuccess
      ..onActionError = _joinError
      ..join();
    
    void _joinSuccess() {
      //You can navigate to the conference page on your own in this success callback of joining a conference.
      Navigator.push(
        context,
        MaterialPageRoute(
          builder: (context) => ConferenceMainPage(),
        ),
      );
    }
    
    void _joinError(ConferenceError error, String message) {
      debugPrint("code: $error message: $message");
    }
