[BUG] Video starts from 00:00 on device orientation change

[sha3rawi33]

History check I checked previous error history and nearly found nothing helpful.

Describe the bug

• When screen orientation is changed; the video will start from the beginning (00:00)
• screen orientation can change and produce the error due to : 1- rotating your device from portrait to landscape or vice-versa 2- clicking on the full-screen button on the player, either to enter full-screen mode or to exit it (this means changing orientation mentioned upper)

To Reproduce Steps to reproduce the behavior:

1. Play video.
2. Use the full-screen button or rotate the screen.
3. [ERROR] video will start from the beginning.

*Example code I'm using the demo code of the "resolutions" page HERE

EXCEPT I'm passing the links of the videos on navigation like:

Navigator.of(context).pushNamed(PlayerScreen.routeName, arguments: NavigatorArguments(videoId /*vimeo video ID*/, videoLinks /*Map variable with resolutions links like {"360p":"url.mp4"}*/, lesson.title/*Name of video lesson*/, myLoadedCourse.instructor/*video author*/));

Player Screen Code:

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

// Class for accessing navigator's passed data
class NavigatorArguments {
  final String videoId; // Vimeo video ID to be used as cache key
  final Map videoLinks; // a Map containing video links like: {"1080p":"video_url.mp4"}
  final String title; // video title to be shown on the notification player
  final String author; // video author to be shown on the notification player

  //initialize
  NavigatorArguments(
      this.videoId,
      this.videoLinks,
      this.title,
      this.author,
      );
}

class PlayerScreen extends StatefulWidget {
  static const routeName = '/player';

  @override
  _PlayerScreenState createState() => _PlayerScreenState();
}

class _PlayerScreenState extends State<PlayerScreen> {
  NavigatorArguments args; //this will carry all passed data

  BetterPlayerController _betterPlayerController;
  GlobalKey _betterPlayerKey = GlobalKey();

  @override
  void initState() {
    BetterPlayerConfiguration betterPlayerConfiguration = BetterPlayerConfiguration(
      aspectRatio: 16 / 9,

        forwardSkipTimeInMilliseconds: 10000,

    );

    _betterPlayerController = BetterPlayerController(betterPlayerConfiguration);
    _betterPlayerController.setBetterPlayerGlobalKey(_betterPlayerKey);

    super.initState();
  }
