Auto rotate in full screen

Auto rotate in full screen when device rotate in landscape and minimise in potrait....same as YouTube.

BufferIndicator doesn't appear

if video not initialize ready to play will have more video controller play much more when we click

if video first time not initialize ready to play video play will

count by click other video
crash video player
can not stop it unless app kill.

by solution i have to share with you with neeko Player

Listener video completed initialize make sure the first video done for Video Player can play it.
Prevent user click other video before success initialize by show loading dialog on screen.
sometime core lib neeko not sure video completed to play because sometime i guest that video show play controller allow user click to play but video not completed init yet. avoid like that please delayed hide loading view for user when notify loadVideoSuccess().
`
NeekoPlayerWidget player;
VideoControllerWrapper videoControllerWrapper;

//Listener func callback
VoidCallback loadVideoSuccess() {
//Delay
Future.delayed(const Duration(milliseconds: 4000), () {
//hide your dialog progress.
});
}
if (videoControllerWrapper == null) {
videoControllerWrapper = VideoControllerWrapper(DataSource.network(
widget.lessonFromList.videoTutorial.toString(),
displayName: widget.lessonFromList.name));
videoControllerWrapper.addListener(loadVideoSuccess);
}
@OverRide
void initState() {
if (videoControllerWrapper == null) {
videoControllerWrapper = VideoControllerWrapper(DataSource.network(
widget.lessonFromList.videoTutorial.toString(),
displayName: widget.lessonFromList.name));
videoControllerWrapper.addListener(loadVideoSuccess);
}
}

@OverRide
Widget build(BuildContext context) {
player = NeekoPlayerWidget(
playerOptions:
NeekoPlayerOptions(preferredOrientationsWhenExitLandscape: [
DeviceOrientation.portraitUp,
DeviceOrientation.portraitDown,
], useController: true),
onPortraitBackTap: () {},
videoControllerWrapper: videoControllerWrapper,
);
return Container(
color: AppColor.appBgColor,
child: player);
}
`

Is this unable to forward and backward video?

inFullScreen paramter in NeekoPlayerWidget is not working

Basically I need to fullscreen the video when the Orientation is landscape.
So I have used OrienationBuilder in my app.

NeekoPlayerWidget(
                                  videoControllerWrapper: playerController,
                                  isPip: isPip || isMediumSize,
                                  inFullScreen:
                                      orientation == Orientation.landscape,
                                )

But the video stays the the same when the orientation changes

Support for subtitles?

video_payer supports the display of subtitles. How can I use them in neeko?

Foreground Play

Does it support background playback and foreground control?

local video gives exception

When I use
```
(DataSource.asset(
"pushup1.mp4",
displayName: "displayName"));

it gave the following exception

`E/ExoPlayerImplInternal(  764): Source error.

Here is my code :

import 'package:flutter/material.dart';
import 'package:flutter/services.dart';
import 'package:neeko/neeko.dart';
import 'package:flutter/foundation.dart';

class PlayerPage extends StatefulWidget {
  PlayerPage({Key key, @required this.url, @required this.title})
      : super(key: key);

  final String url;
  final String title;

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

class _PlayerPageState extends State<PlayerPage> {
  VideoControllerWrapper videoControllerWrapper;

  @override
  void initState() {
    super.initState();
    videoControllerWrapper = VideoControllerWrapper(
        DataSource.network(widget.url, displayName: widget.title));
    SystemChrome.setEnabledSystemUIOverlays([SystemUiOverlay.top]);
  }

  @override
  void dispose() {
    SystemChrome.restoreSystemUIOverlays();
    super.dispose();
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: NeekoPlayerWidget(
        playerOptions: NeekoPlayerOptions(autoPlay: true, isLive: true),
        videoControllerWrapper: videoControllerWrapper,
      ),
    );
  }
}

The player's works perfectly if i set the autoplay and live to false tho.

Hide back button on player

Hi, anyone else knows how to hide the back button on the player?

The way how I use the plugin was like this

NeekoPlayerWidget( onSkipPrevious: () { print("previous"); _videoControllerWrapper.prepareDataSource(DataSource.network( "https://.......video........mp4")); }, onSkipNext: () { print("next"); _videoControllerWrapper.prepareDataSource(DataSource.network( "https://.......video........mp4")); }, videoControllerWrapper: _videoControllerWrapper, ),

Player doesn't support all online video streaming links

I am streaming some anime content on this player(it is nice by the way), but the player cannot recognize the links in some cases and is unable to play the video. Also when pressing the back button from the fullscreen mode, it would be better if it returns the portrait mode. The player does not show you a circular progress indicator when loading or buffering the video. Finally, is it possible that the loaded video parts stays in memory temporary, only while watching, so that when scrolling the video it does not load all over again. Thank you for this wonderful plugin. Keep going.

The Widget is in a hierarchy like this:

MaterialApp(
 Scaffold(
 StatefulWidget(
  Container(
   FutureBuilder(
    Column(
      Expanded(
       Container(
        ListView(
         StatefulWidget(
          Container(
           NeekoPlayerWidget())))))))))))

and i dont know whats wrong, if i try it like in the example it works
