Here is a step-by-step guide.<h3 style="margin-left:0px;">Environment Preparations</h3>Flutter 3.0 or higher version.<h3 style="margin-left:0px;">Step 1. Activate the service</h3>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 <code>SDKAppID, SDKSecretKey</code>. They will be used in <a href="https://trtc.io/document/54896#8495693e-91ce-41ac-92ee-728b33a7714b">Step 5</a>. For specific steps, please refer to <a href="https://trtc.io/document/59832#">activate the Service.</a>﻿<h3 style="margin-left:0px;">Step 2. Import the component</h3>Execute the following command in the command line to install the <a href="https://pub.dev/packages/tencent_calls_uikit">tencent_calls_uikit</a> plugin.<pre><code class="language-javascript">flutter pub add tencent_calls_uikit</code></pre><h3 style="margin-left:0px;">Step 3. Configure the project</h3>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 <code>android/app/build.gradle</code> file of the project:<pre><code class="language-javascript"> android {
 ...... 
 buildTypes { 
 release { 
 ......
 minifyEnabled true 
 proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' 
 } 
 }
}</code></pre>Create a <code>proguard-rules.pro</code> file in the <code>android/app</code> directory of the project, and add the following code in the <code>proguard-rules.pro</code> file:<pre><code class="language-javascript">-keep class com.tencent.** { *; }</code></pre>2. Configure to enable Multidex support in the <code>android/app/build.gradle</code> file of your project.<pre><code class="language-javascript"> android { 
 ......
 defaultConfig {
 ......
 multiDexEnabled true
 } 
}</code></pre>Optional If you need to debug on an iOS Simulator and your Mac Computer uses an Intel Chip, you need to add the following code in the <code>ios/Podfile</code> file:<pre><code class="language-javascript">target 'xxxx' do
 ......
end
......
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['VALID_ARCHS'] = 'arm64 arm64e x86_64'
 config.build_settings['VALID_ARCHS[sdk=iphonesimulator*]'] = 'x86_64'
 end
 end
end</code></pre>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 <code>Info.plist</code>, under the first-level <code>&lt;dict&gt;</code> directory, add the following two items. They correspond to the system's prompt messages when asking for microphone and camera permissions.<pre><code class="language-javascript">&lt;key&gt;NSCameraUsageDescription&lt;/key&gt;
&lt;string&gt;CallingApp needs to access your camera to capture video.&lt;/string&gt;
&lt;key&gt;NSMicrophoneUsageDescription&lt;/key&gt;
&lt;string&gt;CallingApp needs to access your microphone to capture audio.&lt;/string&gt;</code></pre><h3 style="margin-left:0px;">Step 4: Set up navigatorObservers</h3>1. In the Flutter application framework, add TUICallKit.navigatorObserver to navigatorObservers. For example, using the MaterialApp framework, the code is as follows:<pre><code class="language-javascript">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],
 ......
 );
 }
}</code></pre><h3 style="margin-left:0px;">Step 5: Log in to the TUICallKit Component</h3>Use the <a href="https://trtc.io/document/54906#72a9fc1e-cc73-4973-b272-1bd7a891b707">login</a> interface to complete the log-in. For specific usage, refer to the following code:<pre><code class="language-javascript">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}');
 }
}</code></pre><h3 style="margin-left:0px;">Step 6. Make your first phone call</h3>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.<pre><code class="language-javascript">TUICallKit.instance.call('Android', TUICallMediaType.audio);import 'package:tencent_calls_uikit/tencent_calls_uikit.dart';
......
void call() {
 TUICallKit.instance.call('Android', TUICallMediaType.audio);
}</code></pre><img src="https://trtc.io/media/60364655-ab4e-4d16-89b5-2b119d9c6e76.png" alt="Screenshot 2024-06-27 at 14.18.03.png">For more details and features, <a href="https://trtc.io/document/54896?platform=flutter&amp;product=call">please click TencentRTC documentation</a>.<h2 id="Conclusion" id="Conclusion" id="Conclusion" id="Conclusion" style="text-align:justify;">Conclusion</h2>In conclusion, <a href="https://trtc.io/document/54896?platform=flutter&amp;product=call">building a Flutter video call application</a> leverages the robust capabilities of Flutter, enabling seamless video communication with a range of features.
