Web (alpha)

The agora_rtc_engine for web is currently in alpha stage, and the documentation is incomplete and it has only been tested on desktop web at this time.

The agora_rtc_engine web is built on top of iris_web, a wrapper for the Agora Web SDK 4.x. This helps align the Native SDK (Android/iOS/macOS/Windows) APIs through the Agora Web SDK 4.x. Please note that the agora_rtc_engine web utilizes the Agora Web SDK 4.x underneath, so only a subset of the Native SDK APIs can be implemented on the web. If the APIs return AgoraRtcException with a -4 error code, this means these APIs are not supported at this time.

Download the iris_web(see the link below) artifact and include it as a <script /> tag in your <your-project>/web/index.html file. For example:

Project structure

<your-project>
|__web
   |__index.html
   |__iris-web-rtc_<x.y.z>.js

<!-- <your-project>/web/index.html -->
<!DOCTYPE html>
<html>
...
<body>
  ...
  <script src="iris-web-rtc_<x.y.z>.js"></script>
</body>
</html>

For Testing Purposes

You can directly depend on the Agora CDN for testing purposes:

<!-- <your-project>/web/index.html -->
<!DOCTYPE html>
<html>
...
<body>

  <script src="https://download.agora.io/sdk/release/iris-web-rtc_n450_w4220_0.8.6.js"></script>
</body>
</html>

Interact with Agora RTC Native SDK(Android/iOS only)

NOTE: This feature requires agora_rtc_engine >= 6.3.0

Due to performance constraints, direct implementation of advanced features like video and audio raw data processing is not currently feasible in Flutter side.

We enable you to create an RtcEngine within Flutter by utilizing the native handle from the RtcEngine(Android) or AgoraRtcEngineKit(iOS) of the Agora RTC Native SDK. This approach enables your application to directly utilize the advanced features of the Agora RTC Native SDK through the agora_rtc_engine package, bridging the gap between native capabilities and Flutter's environment.

More detail, please check the ProcessVideoRawData example for reference.
