TRTC SDK（Flutter）

Product News

In order to improve your access experience, we have launched a new and better Flutter plugin: tencent_rtc_sdk.

Quick Start

Sample Code

1.Initialization

// Create TRTCCloud singleton
trtcCloud = await TRTCCloud.sharedInstance();
// Tencent Cloud Audio Effect Management Module
txDeviceManager = trtcCloud.getDeviceManager();
// Beauty filter and animated effect parameter management
txBeautyManager = trtcCloud.getBeautyManager();
// Tencent Cloud Audio Effect Management Module
txAudioManager = trtcCloud.getAudioEffectManager();

2.Room entry/exit

// Room entry/exit
trtcCloud.enterRoom(
        TRTCParams(
            sdkAppId: sdkAppId,
            userId: userId,
            userSig: userSig,
            roomId: roomId),
        TRTCCloudDef.TRTC_APP_SCENE_VIDEOCALL);
// Leave a room
trtcCloud.exitRoom();

3.Listener registration

// Register a listener
trtcCloud.registerListener(onRtcListener);
onRtcListener(type, param) {
  // Callback for room entry
  if (type == TRTCCloudListener.onEnterRoom) {
    if (param > 0) {
      showToast('Entered the room successfully');
    }
  }
  // Callback for the entry of a remote user
  if (type == TRTCCloudListener.onRemoteUserEnterRoom) {
    // The parameter is the user ID of the remote user.
  }
  // Whether the remote user has a playable primary image (generally for camera)
  if (type == TRTCCloudListener.onUserVideoAvailable) {
    //param['userId'] is the user ID of the remote user
    //param['visible'] indicates whether image is enabled
  }
}
//Remove a listener
trtcCloud.unRegisterListener(onRtcListener);

4.Playing local video

// Parameters:
// frontCamera: `true`: front camera; `false`: rear camera
// viewId: view ID generated by `TRTCCloudVideoView`
TRTCCloudVideoView(
    onViewCreated: (viewId) {
      trtcCloud.startLocalPreview(true, viewId);
});

5.Display remote video

// Parameters:
// userId: Specifies the userid of the remote user
// streamType: Specifies the type of video stream to watch userid：
//* HD big picture：TRTCCloudDef.TRTC_VIDEO_STREAM_TYPE_BIG
//* Low definition large picture：TRTCCloudDef.TRTC_VIDEO_STREAM_TYPE_SMALL
// viewId: view ID generated by `TRTCCloudVideoView`
TRTCCloudVideoView(
    onViewCreated: (viewId) {
      trtcCloud.startRemoteView(userId, TRTCCloudDef.TRTC_VIDEO_STREAM_TYPE_SMALL, viewId);
});

5.Display remote screen sharing

/// Parameters:
/// userId: Specifies the userid of the remote user
/// streamType: type of the remote user’s video stream to play:
///* Substream (screen sharing): TRTCCloudDe.TRTC_VIDEO_STREAM_TYPE_SUB
/// viewId: view ID generated by `TRTCCloudVideoView`
TRTCCloudVideoView(
    onViewCreated: (viewId) {
      trtcCloud.startRemoteView(userId, TRTCCloudDef.TRTC_VIDEO_STREAM_TYPE_SUB, viewId);
});

Common problem

How do I view TRTC logs?

TRTC logs are compressed and encrypted by default with the XLOG extension. You can set setLogCompressEnabled to specify whether to encrypt logs. If a log filename contains C (compressed), the log is compressed and encrypted; if it contains R (raw), the log is in plaintext.

iOS：Documents/log of the application sandbox
Android:
- 6.7 or below: /sdcard/log/tencent/liteav
- 6.8 or above: /sdcard/Android/data/package name/files/log/tencent/liteav/

iOS cannot display video (Android is good)

Please confirm io.flutter.embedded_views_preview is YES in your info.plist
