インテグレーション

This article will guide you through the process of integrating the TUICallKit component quickly. By following this documentation, you can complete the access work in just 10 minutes and ultimately obtain an application with a complete user interface as well as audio and video calling features.
Video Call
Group call







Environment Preparations

Flutter 3.0 or higher version.

Step 1. Activate the service

Before using the audio and video services provided by Tencent Cloud, you need to go to the console to activate the audio and video services for your application, and obtain SDKAppID, SDKSecretKey. They will be used in Step 5. For specific steps, please refer to activate the Service.

Step 2. Import the component

Execute the following command in the command line to install the tencent_calls_uikit plugin.
flutter pub add tencent_calls_uikit

Step 3. Configure the project

Android
iOS
1. If you need to compile and run on the Android platform, since the SDK uses Java's reflection feature internally, certain classes in the SDK must be added to the non-aliasing list.
First, configure and enable obfuscation rules in the android/app/build.gradle file of the project:
  android {
    ......    
    buildTypes {  
        release {  
            ......
            minifyEnabled true  
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'  
        } 
    }
}
Create a proguard-rules.pro file in the android/app directory of the project, and add the following code in the proguard-rules.pro file:
-keep class com.tencent.** { *; }
2. Configure to enable Multidex support in the android/app/build.gradle file of your project.
  android {  
    ......
    defaultConfig {
      ......
      multiDexEnabled true
    } 
}
Since TUICallKit uses iOS's audio and video features, you need to grant permissions for the use of the microphone and camera.
Authorization Operation Method: In your iOS project's Info.plist, under the first-level <dict> directory, add the following two items. They correspond to the system's prompt messages when asking for microphone and camera permissions.
<key>NSCameraUsageDescription</key>
<string>CallingApp needs to access your camera to capture video.</string>
<key>NSMicrophoneUsageDescription</key>
<string>CallingApp needs to access your microphone to capture audio.</string>

Step 4: Set up navigatorObservers

1. In the Flutter application framework, add TUICallKit.navigatorObserver to navigatorObservers. For example, using the MaterialApp framework, the code is as follows:
import 'package:tencent_calls_uikit/tencent_calls_uikit.dart';

 ......

class XXX extends StatelessWidget {
  const XXX({super.key});

 @override
  Widget build(BuildContext context) {
    return MaterialApp(
      navigatorObservers: [TUICallKit.navigatorObserver],
      ......
    );
  }
}

Step 5: Log in to the TUICallKit Component

Use the login interface to complete the log-in. For specific usage, refer to the following code:
import 'package:tencent_calls_uikit/tencent_calls_uikit.dart';
import 'package:tencent_calls_uikit/debug/generate_test_user_sig.dart';
......

final String userID    = 'xxxxx'; // Please replace with your UserId
final int    sdkAppID  = 0;       // Please replace with the SDKAppID you got from the console in step 1
final String secretKey = 'xxxx';  // Please replace with the SecretKey you got from the console in step 1

void login() async {
    String userSig  = GenerateTestUserSig.genTestSig(userID, sdkAppID, secretKey);
    TUIResult result = await TUICallKit.instance.login(sdkAppID, userID, userSig);
    if (result.code.isEmpty) {
      print('Login success');
    } else {
      print('Login failed: ${result.code} ${result.message}');
    }
}
Parameter
Type
Description
userID
String
Customers define their own User ID based on their business. You can only include letters (a-z, A-Z), digits (0-9), underscores, and hyphens.
sdkAppID
int
The unique identifier of the audio and video application created in the Tencent RTC Console.
secretKey
String
SDKSecretKey for the audio and video application created in Tencent RTC Console.
userSig
String
A security protection signature used for user log in authentication to confirm the user's identity and prevent malicious attackers from stealing your cloud service usage rights.
Note:
Development Environment: If you are in the local development and debugging stage, you can use the local GenerateTestUserSig.genTestSig function to generate userSig. In this method, the SDKSecretKey is vulnerable to decompilation and reverse engineering, and once your key is leaked, attackers can steal your Tencent Cloud traffic.
Production Environment: If your project is going to be launched, please adopt the method of Server-side Generation of UserSig.

Step 6. Make your first phone call

After both the caller and callee have successfully signed in, the caller can initiate an audio or video call by calling the TUICallKit's call method and specifying the call type and the callee's userId. At this point, the callee will receive an incoming call invitation.

TUICallKit.instance.call('Android', TUICallMediaType.audio);import 'package:tencent_calls_uikit/tencent_calls_uikit.dart';
......

void call() {
    TUICallKit.instance.call('Android', TUICallMediaType.audio);
}
