enterRoom method Null safety

Future<void> enterRoom(
  1. TRTCParams param,
  2. int scene
)

Enter room

After calling this API, you will receive the onEnterRoom(result) callback from TRTCCloudListener:

If room entry succeeded, result will be a positive number (result > 0), indicating the time in milliseconds (ms) used for entering the room.

If room entry failed, result will be a negative number (result < 0), indicating the error code for room entry failure.

Parameters:

param Room entry parameters. For more information, please see the definition of the TRTCParams parameter in trtc_cloud_def.dart

scene Application scenario. Currently, video call (VideoCall), live streaming (Live), audio call (AudioCall), and voice chat room (VoiceChatRoom) are supported.

Note:

  1. If scene is selected as TRTC_APP_SCENE_LIVE or TRTC_APP_SCENE_VOICE_CHATROOM, you must use the role field in TRTCParams to specify the role of the current user.

  2. No matter whether room entry is successful, enterRoom must be used together with exitRoom. If enterRoom is called again before exitRoom is called, an unexpected error will occur.

Implementation

Future<void> enterRoom(TRTCParams param, int scene) {
  if (Platform.isAndroid || Platform.isWindows) {
    return _channel.invokeMethod('enterRoom', {
      "sdkAppId": param.sdkAppId,
      "userId": param.userId,
      "userSig": param.userSig,
      "roomId": param.roomId.toString(),
      "strRoomId": param.strRoomId,
      "role": param.role,
      "streamId": param.streamId,
      "userDefineRecordId": param.userDefineRecordId,
      "privateMapKey": param.privateMapKey,
      "businessInfo": param.businessInfo,
      "scene": scene,
    });
  } else {
    return _channel.invokeMethod('enterRoom', {
      "param": jsonEncode(param),
      "scene": scene,
    });
  }
