Experimental Features

Interact with RtcEngine/AgoraRtcEngineKit on Android/iOS

agora_rtc_engine has not implemented all the features of agora native (Android/iOS) sdk, due to performance reasons, such as Custom Audio Source and Renderer, Custom Video Source and Renderer, Raw Audio Data, etc.

agora_rtc_engine provides RtcEnginePlugin/RtcEnginePlugin, allowing you to to interact with the RtcEngine created on the Flutter side in the Android/iOS code, you can implement your own plugin by inheriting RtcEnginePlugin/RtcEnginePlugin, and get the RtcEngine/AgoraRtcEngineKit in the onRtcEngineCreated callback.

Please note that you should not call the RtcEngine.destroy/AgoraRtcEngineKit.destroy function on Android/iOS code, because it will affect the RtcEngine on the Flutter side. To see how to use RtcEnginePlugin, please check the custom audio source example:

Android: CustomCaptureAudioPlugin.kt

iOS: CustomCaptureAudioPlugin.swift
