I'm testing a dependency of flutter and having these issues while trying to show video streaming using ngrok, these are the issues i have:
E/VLC (15337): [00000071a614bc90/3c35] libvlc stream: HTTP connection failure
E/VLC (15337): [00000071a614bc90/3c35] libvlc stream: connection failed: Network is unreachable
E/VLC (15337): [00000071a614bc90/3c35] libvlc stream: cannot connect to ae872c2bd308.ngrok.io:80
and this is code I'm using:
import 'package:flutter/material.dart';
import 'package:flutter_vlc_player/flutter_vlc_player.dart';
void main() {
runApp(MyApp());
}
class MyApp extends StatelessWidget {
// This widget is the root of your application.
#override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Flutter Demo',
theme: ThemeData(
visualDensity: VisualDensity.adaptivePlatformDensity,
),
home: MyHomePage(),
);
}
}
class MyHomePage extends StatefulWidget {
MyHomePage({Key key}) : super(key: key);
#override
_MyHomePageState createState() => _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> {
VlcPlayerController _videoPlayerController;
#override
void initState() {
super.initState();
_videoPlayerController = VlcPlayerController.network(
'http://ae872c2bd308.ngrok.io/stream',
hwAcc: HwAcc.FULL,
autoPlay: false,
options: VlcPlayerOptions(),
);
}
#override
void dispose() async {
super.dispose();
await _videoPlayerController.stopRendererScanning();
await _videoPlayerController.dispose();
}
#override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(),
body: Center(
child: VlcPlayer(
controller: _videoPlayerController,
aspectRatio: 16 / 9,
placeholder: Center(child: CircularProgressIndicator()),
),
),
);
}
}
Any idea of what could be the problem?
I tested the transmission using VLC player and it is possible to make it work.
Add autoPlay: true to the controller so it becomes
_videoPlayerController = VlcPlayerController.network(
'http://ae872c2bd308.ngrok.io/stream',
hwAcc: HwAcc.FULL,
autoPlay: true,
options: VlcPlayerOptions(),
);

When you first switch to a map widget, the map opens normally. If you return to the previous widget and go to the map again, an error occurs.

If you restart, the card is loaded.I.e. the card opens only after restart.
Sometimes writes console: ChromeProxyService: Failed to evaluate expression 'androidOSMLifecycle': InternalError: Expression evaluation in async frames is not supported. No frame with index 16..
How to solve such a problem? The problem occurs on initPositionMap.
I have made a new file in my views folder but whenever I turn on the emulator and run the code, it just says "Hello World".
Is there a way I can set the starting point of the project to be on this new file? Because it only seems to turn on the main.dart file.
This is the code that is in the views file called home_page.dart . It is supposed to just say "Hi" 10 times.
import 'package:flutter/material.dart';
import '../models/post.dart';
class HomePage extends StatefulWidget {
const HomePage({Key? key}) : super(key: key);
#override
_HomePageState createState() => _HomePageState();
}
class _HomePageState extends State<HomePage> {
List<Post>? posts;
var isLoaded = false;
#override
void initState() {
super.initState();
//fetch data from API
getData();
}
getData() async {
// posts = await
}
#override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: const Text('Posts'),
),
body: ListView.builder(
itemCount: 10,
itemBuilder: (context, index) {
return Container(
child: Text('Hi'),
);
},
)
);
}
}
in flutter the main.dart file is the first file
import 'package:flutter/material.dart';
import 'package:get/get_navigation/src/root/get_material_app.dart';
void main() {

Is there something I am missing setting up the VLC on flutter? Only empty. No player seen just a blank page here is my flutter code, just followed from their documentation. Here is the code. I might miss something. Is there any alternative way to use the VLC plugin? I am new to Flutter. Thank you

try to add setstate in initState, or intime equal vlccontroller to VlcPlayerController.network
this is my code thats i m trying by using flutter vlc player but its not working so any can help me to solving the issue or i can show stream with another way?
so you guys can give me any suggestion or give any little example. i m trying to solve this issue from last two hours but its not going
import 'package:flutter/material.dart';
import 'package:flutter_vlc_player/flutter_vlc_player.dart';
import 'package:flutter_vlc_player/vlc_player.dart';
import 'package:flutter_vlc_player/vlc_player_controller.dart';
void main() {
runApp(MyApp());
}
class MyApp extends StatelessWidget {
// This widget is the root of your application.
#override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Flutter Demo',
theme: ThemeData(
visualDensity: VisualDensity.adaptivePlatformDensity,

home: MyHomePage(),
);
}
}
class MyHomePage extends StatefulWidget {
MyHomePage({Key key}) : super(key: key);
#override
_MyHomePageState createState() => _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> {
VlcPlayerController _videoPlayerController;
#override
void initState() {
super.initState();
_videoPlayerController = VlcPlayerController.network(
'rtsp://viewer:aeDoPhiucees3gohshie#173.249.14.110:27954/axis-media/media.amp?videocodec=h264&fps=15&audio=1&resolution=640x480',
hwAcc: HwAcc.FULL,
autoPlay: false,
options: VlcPlayerOptions(),
);
}
#override
void dispose() async {
super.dispose();
await _videoPlayerController.stopRendererScanning();
await _videoPlayerController.dispose();
}
#override

return Scaffold(

body: Center(
child: VlcPlayer(
controller: _videoPlayerController,
aspectRatio: 16 / 9,
placeholder: Center(child: CircularProgressIndicator()),
),
),
);
}
}
Here is a small example that works for me. I think the problem is that in the newer versions the Controller must be initialized immediately.
The only problems I have with this code is that the advanced options take no effect. Unfortunately it is hard to find some good information

class _MyHomePageState extends State<MyHomePage> {
VlcPlayerController _vlcViewController = new VlcPlayerController.network(

);
}

Check out this lib: https://pub.dev/packages/flutter_playout. It does support HLS.
How can I catch the opening and closing of the drawer in flutter? In principle, two objects must be are used for this purpose: DrawerController, which "holds" the drawer and the drawerCallback. drawerCallback should track the opening and closing of the drawer, but the code that is discussed at https://github.com/flutter/flutter/issues/21272 and https://github.com/flutter/flutter/issues/23630 does not works. Anyone can advise something?
Update 2021-12:
Scaffold(
drawer: DrawerWidget(),
onDrawerChanged: (isDrawerOpen) {
if(isDrawerOpen) {
//drawer is open
} else {
//drawer is close
}
},
body: bodyWidget(),
)
You can first refer to other people's replies on stackoverflow here
My solve:
get Drawer status on DrawerWidget
initState() : open drawer
dispose() : close drawer
Stream drawer status by DrawerService Provider
