Tencent Cloud Voice Call and Video Call

Tencent Cloud Voice Call and Video Call plug-in, supports both one-to-one and group calling.

This plug-in integrate Tencent Real-Time communication(TRTC) and Tencent Cloud Chat.

• TRTC SDK: Used as the calling module for voice/video calling.
• Chat SDK: Used for sending chat messages and signal messages.

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.

Get started

What needs to be done before we start

• Create a Flutter application.
• Signed up for a Tencent Cloud account and completed identity verification.
• Created a chat application as instructed in Creating and Upgrading an Application and recorded the SDKAppID.
• Enable the [Tencent Real-Time Communication] on the right bottom of Tencent Cloud IM console.
• [Optional] Integrate one of our Chat SDK to your APP, non-UI Pure SDK or UIKit.
• Add tim_ui_kit_calling_plugin to dependencies in pubspec.yaml file. Or by executing following commands.

/// step 1:
flutter pub add tim_ui_kit_calling_plugin

/// step 2:
flutter pub get

Step 1: Add navigatorKey

Add navigatorKey to MateriaApp. Aimed of navigate to calling page when receiving calling invitation.

import 'package:tim_ui_kit_calling_plugin/tim_ui_kit_calling_plugin.dart';


MaterialApp(
    navigatorKey: TUICalling.navigatorKey,
    ...
)

Step 2: Initialize Calling Service

We recommend you to do this step after login, if you tend to add calling function to current Flutter Chat application.

Use init(sdkAppID: sdkAppId, userID: userID, userSig: userSig) to initialize plug-in, it will deal with receiving calling invitation automatically, and help you to intialize and login IM, to send invitation.

    class  HomePageState extends State<HomePage> {
        final TUICalling _calling = TUICalling();

        @override
        initState() {
            super.initState();
            final userID = '1234756';
            final userSig = '';
            final sdkAppId = 0; /// sdkAppID from Tencent Cloud IM control
            _calling.init(sdkAppID: sdkAppId, userID: userID, userSig: userSig);
        }
    }

• The correct way to issue UserSig is to integrate the calculation code of UserSig into your server, and provide an App-oriented interface. When UserSig is needed, your App initiates a request to the business server to obtain the dynamic UserSig `. For more details, please refer to Server Generates UserSig.

QA

1: How to customize the call interface?。

This plug-in provides single and multi-person calls by default. If you need to customize the call interface, please use the enableCustomViewRoute method to open the custom view. After enabling, after receiving the audio and video call invitation, the audio and video call pages will not be automatically opened. You can use the setCallingListener method to set message monitoring and monitoring of user entry and other information to achieve invitation sending and receiving and audio and video calling services. Also use sharedInstance to get a TRTCCalling instance. This instance provides TRTC related capabilities, such as switch camera, switch microphone, hang up, answer, etc.
