The example does not work on Android

[Marcus-Ospicon]

Hi, I try to use your sample on my emulator device but it doesn't work for me, please help me. I created a list view with a title and open the camera page when tapping on it My camera_view.dart code is

import 'package:flutter/material.dart';
import 'package:flutter_vlc_player/flutter_vlc_player.dart';

class MenuCameraView extends StatefulWidget {
  @override
  _MenuCameraViewState createState() => _MenuCameraViewState();
}

class _MenuCameraViewState extends State<MenuCameraView> {
  final String urlToStreamVideo = 'https://commondatastorage.googleapis.com/gtv-videos-bucket/sample/ForBiggerJoyrides.mp4';
  static final VlcPlayerController controller = VlcPlayerController(
      // Start playing as soon as the video is loaded.
      onInit: () {
    controller.play();
  });
  final double playerWidth = 360;
  final double playerHeight = 240;

  @override
  void dispose() {
    controller.dispose();
    super.dispose();
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Center(
        child: Container(
          height: playerHeight,
          width: playerWidth,
          child: VlcPlayer(
            aspectRatio: 16 / 9,
            url: urlToStreamVideo,
            controller: controller,
            placeholder: Center(child: CircularProgressIndicator()),
          ),
        ),
      ),
    );
  }
}

# The following defines the version and build number for your application.
# A version number is three numbers separated by dots, like 1.2.43
# followed by an optional build number separated by a +.
# Both the version and the builder number may be overridden in flutter
# build by specifying --build-name and --build-number, respectively.
# In Android, build-name is used as versionName while build-number used as versionCode.
# Read more about Android versioning at https://developer.android.com/studio/publish/versioning
# In iOS, build-name is used as CFBundleShortVersionString while build-number used as CFBundleVersion.

  uses-material-design: true

  # To add assets to your application, add an assets section, like this:
  assets:
    - assets/images/roundwave_logo.png
    - assets/images/devices/rts_1x33_white.non-shadow.gif
    - assets/images/devices/rmo_110_white.non-shadow.gif

    - assets/images/USA-Flag-icon.jpg
    - assets/i18n/en.json
    - assets/i18n/vi.json

  # An image asset can refer to one or more resolution-specific "variants", see
  # https://flutter.dev/assets-and-images/#resolution-aware.

  # For details regarding adding assets from package dependencies, see
  # https://flutter.dev/assets-and-images/#from-packages

  # To add custom fonts to your application, add a fonts section here,
  # in this "flutter" section. Each entry in this list should have a
  # "family" key with the font family name, and a "fonts" key with a
  # list giving the asset and other descriptors for the font. For
  # example:
  fonts:
    - family: Microsoft Sans Serif
      fonts:
        - asset: assets/fonts/Microsoft_Sans_Serif.ttf
  #   - family: Trajan Pro
  #     fonts:
  #       - asset: fonts/TrajanPro.ttf
  #       - asset: fonts/TrajanPro_Bold.ttf
  #         weight: 700
