This document describes how to quickly run the demo for the TRTC Flutter SDK.
notice
 Currently, screen sharing and device selection are not supported on Windows or macOS.
Environment Requirements
Flutter 2.0 or later
Developing for Android:
Android Studio 3.5 or later
Devices with Android 4.1 or later
Developing for iOS and macOS:
Xcode 11.0 or later
OS X 10.11 or later
A valid developer signature for your project
Developing for Windows:
OS: Windows 7 SP1 or later (64-bit based on x86-64)
Disk space: At least 1.64 GB of space after the IDE and relevant tools are installed
﻿Visual Studio 2019﻿
Prerequisites
You have signed up for a Tencent Cloud account.
Directions
Step 1. Create an application
1. Log in to the TRTC console and select RTC Engine on the left sidebar.
2. Click Start now, enter an application name such as APIExample. If you already have an application, click link existing application.
3. Add or edit tags according to your actual business needs and click Create application.
﻿
﻿
step 2. Get your SDKAppId and SecretKey
After your application created, you can get your SDKAppID and SecretKey on Basic informaction. SDKAppID and SecrentKey is needed for running demo.
﻿
﻿
Step 3. Download the sample code
Go to GitHub to download the SDK and demo source code.
git clone https://github.com/LiteAVSDK/TRTC_Flutter.git
Step 4. Configure the project
Open the file downloaded previously, find and open /lib/debug/GenerateTestUserSig.dart, and set the following parameters:
SDKAPPID: A placeholder by default. Set it to the actual SDKAppID.
SECRETKEY: A placeholder by default. Set it to the actual key.
explain
﻿
The method for generating UserSig described in this document involves configuring SECRETKEY in the client code. In this method, SECRETKEY may be easily decompiled and reversed, and if your key is disclosed, attackers can steal your Tencent Cloud traffic. Therefore, this method is only suitable for the local execution and debugging of TRTC-Simple-Demo.
The best practice is to integrate the calculation code of UserSig into your server and provide an application-oriented API. When UserSig is needed, your application can send a request to your server for a dynamic UserSig. For more information, see How do I calculate UserSig during production?.
Step 5. Compile and run the demo
1. Execute flutter pub get.
2. Build and run the project.
Android
1. Execute flutter run.
2. Open the demo project with Android Studio (3.5 or later), and run the project.
iOS
1. Execute cd ios.
2. Execute pod install.
3. Open /ios in the source code directory with Xcode (11.0 or later). Compile and run the demo project.
Windows
1. Execute flutter config --enable-windows-desktop.
2. Execute flutter run -d windows.
macOS
1. Execute flutter config --enable-macos-desktop.
2. Execute cd macos.
3. Execute pod install.
4. Execute flutter run -d macos.
FAQs
How do I view TRTC logs?
TRTC logs are compressed and encrypted by default (XLOG format). You can find them at the following paths:
iOS: Documents/log of the application sandbox
Android:
v6.7 or earlier: /sdcard/log/tencent/liteav
v6.8 or later: /sdcard/Android/data/package name/files/log/tencent/liteav/
What should I do if videos show on Android but not on iOS?
Make sure that in info.plist of your project, the value of io.flutter.embedded_views_preview is YES. 
What should I do if the "Manifest merge failed" error occurs in Android Studio?
Open /example/android/app/src/main/AndroidManifest.xml.
1. Add xmlns:tools="http://schemas.android.com/tools" to manifest.
2. Add tools:replace="android:label" to application.
