This document will guide you through quickly running the audio and video call Demo. By following this guide, you can run the Demo within 10 minutes and experience an audio and video call feature with a complete UI.
Prerequisites
Environment Setup
Flutter requirements: Flutter 3.24.0 and above.
Android requirements: Android Studio 3.5 and above, and an Android device running Android 4.1 and above.

Activate the Service
Downloading the Demo
1. Download the TUICallKit Demo source code from GitHub, or run the following command in the command line: git clone https://github.com/Tencent-RTC/TUIKit_Flutter.git
2. Open TUIKit_Flutter/application using Android Studio or VS Code. The following steps will use Android Studio as an example.
Running the Demo
We recommend that you run the Demo on two devices, log in with two different user accounts on two devices, one as the caller and one as the callee, to complete an audio/video call experience.
Step 1: Configure and Run the Demo
1. Configure SDKAppID and SecretKey: Open the lib/debug/generate_test_user_sig.dartfile, and fill in the sdkAppId and secretKey obtained during Activate the Service: 2. Run the Demo: You can run the Demo using the following command.
Step 2: Login and Registration
After the Demo starts, please enter an ID in the User ID field. If your current UserID has not been registered, you will enter the registration interface, where you can set a nickname for yourself.
Logged-in User: Charlie |
| Logged-in User: Jane |
|
| | | |
Tip:
Avoid using simple UserIDs such as "1", "123", or "111". These IDs are commonly used during collaborative development and may already be in use by others, resulting in login failures. We recommend using a unique UserID during testing.
Step 3: Make a Call
1. On the caller's device, tap 1V1 Call on the interface, enter the callee's UserID in the pop-up window, and select the desired call type.
2. Click Initiate a Call.
Click Call | Charlie calls Jane | Jane receives the incoming call | The call starts after Jane clicks Answer |
| | | |
Tip:
To start a call, you need to confirm that the Callee User ID is a valid and logged-in ID.
