Why do I obtain black screen for both remote and local users in a video call using agora rtc?

agora.io

I have tried to follow the example of using agora with flutter and have included the permissions as recommended in the documentation. However, whenever I run the app on two emulator devices, I obtain black screens for remote and local users joining the channel.

import 'dart:async';
import 'package:flutter/material.dart';
import 'package:permission_handler/permission_handler.dart';
import 'package:agora_rtc_engine/rtc_engine.dart';
import 'package:agora_rtc_engine/rtc_local_view.dart' as RtcLocalView;
import 'package:agora_rtc_engine/rtc_remote_view.dart' as RtcRemoteView;

const appId = "ba997ed994ca4163a06898c8fd9e7f1b";
const tempToken =
    "006ba997ed994ca4163a06898c8fd9e7f1bIAA4Dx064RTGa9iaVmXQjxtTuvgDsBgiMUiuWhMBW9zsH+LcsooAAAAAEADkBngOXNpIYQEAAQBb2khh";
void main() {
  runApp(MyApp());
}

class MyApp extends StatefulWidget {
  @override
  _MyAppState createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  int? _remoteUid;
  late RtcEngine _engine;
  bool _localUserJoined = false;
  @override
  void initState() {
    // TODO: implement initState
    super.initState();
    initAgora();
  }

  Future<void> initAgora() async {
    // retrieve permissions
    await [Permission.microphone, Permission.camera].request();

    //create the engine
    _engine = await RtcEngine.create(appId);
    await _engine.enableLocalVideo(true);
    await _engine.enableVideo();

    _engine.setEventHandler(
      RtcEngineEventHandler(
        error: (code) {
          setState(() {
            print('OnError: $code');
          });
        },
        joinChannelSuccess: (String channel, int uid, int elapsed) {
          print("local user $uid joined");
          setState(() {
            _localUserJoined = true;
          });
        },
        userJoined: (int uid, int elapsed) {
          print("remote user $uid joined");
          setState(() {
            _remoteUid = uid;
          });
        },
        userOffline: (int uid, UserOfflineReason reason) {
          print("remote user $uid left channel");
          setState(() {
            _remoteUid = null;
          });
        },
      ),
    );

    await _engine.joinChannel(tempToken, "test1", null, 0);
  }

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: const Text('Agora Video Call'),
        ),
        body: Container(
          child: Stack(
            children: [
              Center(
                child: _remoteVideo(),
              ),
              Align(
                alignment: Alignment.bottomRight,
                child: Container(
                  width: 100,
                  height: 150,
                  child: _localUserJoined
                      ? RtcLocalView.TextureView()
                      : const CircularProgressIndicator(),
                ),
              )
            ],
          ),
        ),
      ),
    );
  }

  // Display remote user's video
  Widget _remoteVideo() {
    if (_remoteUid != null) {
      return RtcRemoteView.SurfaceView(uid: _remoteUid!);
    } else {
      return const Text(
        'Please wait for remote user to join',
        textAlign: TextAlign.center,
      );
    }
  }
}

This is what I obtain on the log console when running the app
