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
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(),
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
import 'package:flutter/material.dart';
import 'package:flutter_vlc_player/flutter_vlc_player.dart';
import 'package:flutter_vlc_player/src/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(
primarySwatch: Colors.blue,
),
home: MyHomePage(title: 'Flutter Demo Home Page'),
);
}
}
class MyHomePage extends StatefulWidget {
MyHomePage({Key? key, required this.title}) : super(key: key);
final String title;
#override
_MyHomePageState createState() => _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> {
VlcPlayerController _vlcViewController = new VlcPlayerController.network(
"rtsp://192.72.1.1/liveRTSP/av4",
autoPlay: true,
);
#override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text(widget.title),
),
body: Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
new VlcPlayer(
controller: _vlcViewController,
aspectRatio: 16 / 9,
placeholder: Text("Hello World"),
),
],
),
),
);
}
}
Check out this lib: https://pub.dev/packages/flutter_playout. It does support HLS.

When I restart this code in Visual Studio autofocus is working as well as keyboard is showing. When I close the visual studio and re open the app in android emulator the keyboard is not showing but auto focus is working (Cursor is showing).
But its work in android 5 perfectly.
My code:
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(
primarySwatch: Colors.blue,
),
home: MyHomePage(title: 'Flutter Demo Home Page'),
);
}
}
class MyHomePage extends StatefulWidget {
const MyHomePage({Key? key, required this.title}) : super(key: key);
final String title;
#override
_MyHomePageState createState() => _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> {
#override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text(widget.title),
),
body: Center(
child: TextField(
autofocus: true,
)
),
);
}
}
Can anyone fix this? Thank you.
Try the following code:
void main() {
runApp(MyApp());
}
class MyApp extends StatelessWidget {
#override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Flutter Demo',
theme: ThemeData(
primarySwatch: Colors.blue,
),
home: MyHomePage(title: 'Flutter Demo Home Page'),
);
}
}
class MyHomePage extends StatefulWidget {
const MyHomePage({Key? key, required this.title}) : super(key: key);
final String title;
#override
_MyHomePageState createState() => _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> {
final FocusNode focusNode = FocusNode();
#override
void initState() {
super.initState();
focusNode.requestFocus();
}
#override
void dispose() {
focusNode.dispose();
super.dispose();
}
#override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text(widget.title),
),
body: Center(
child: TextField(
focusNode: focusNode,
autofocus: true,
),
),
);
}
}
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() {
runApp(const MyApp());
}
class MyApp extends StatelessWidget {
const MyApp({Key? key}) : super(key: key);
// This widget is the root of your application.
#override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Flutter Demo',
theme: ThemeData(
primarySwatch: Colors.blue,
),
home: const MyHomePage(title: 'Flutter Demo Home Page'),//add your home page here
);
}
}
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
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}) : super(key: key);
#override
_MyHomePageState createState() => _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> {
late VlcPlayerController _videoPlayerController;
#override
void initState() {
super.initState();
_videoPlayerController = VlcPlayerController.network(
'https://local.clift.mdu1.net/3ABN/index.m3u8',
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()),
),
),
);
}
}```
try to add setstate in initState, or intime equal vlccontroller to VlcPlayerController.network
Good day!
I am a new to Flutter to would like to start my Startup but I was trapped in this problem to make Tabbar example...
I have almost been frustrated all day because of this problems....
Dart Analysis keeps saying this below....
Non-nullable instance field ['controller'] must be initialized in flutter
really appreciate in advance.
import 'package:flutter/material.dart';
import 'sub/firstPage.dart';
import 'sub/secondPage.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(
primarySwatch: Colors.blue,
),
home: MyHomePage(title: 'Flutter Demo Home Page'),
);
}
}
class MyHomePage extends StatefulWidget {
MyHomePage({Key? key, required this.title}) : super(key: key);
final String title;
#override
_MyHomePageState createState() => _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> with SingleTickerProviderStateMixin {
TabController controller;
#override
void initState() {
super.initState();
controller = TabController(length: 2, vsync: this);
}
#override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text('TabBar Example'),
),
body: TabBarView(
children: <Widget>[FirstApp(), SecondApp()],
controller: controller,
),
bottomNavigationBar: TabBar(tabs: [
Tab(icon: Icon(Icons.looks_one, color: Colors.blue),),
Tab(icon: Icon(Icons.looks_two, color: Colors.blue),),
],
)
);
}
#override
void dispose() {
controller.dispose();
super.dispose();
}
}
Plase try, you missed use controller
import 'package:flutter/material.dart';
import 'sub/firstPage.dart';
import 'sub/secondPage.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(
primarySwatch: Colors.blue,
),
home: MyHomePage(title: 'Flutter Demo Home Page'),
);
}
}
class MyHomePage extends StatefulWidget {
MyHomePage({Key? key, required this.title}) : super(key: key);
final String title;
#override
_MyHomePageState createState() => _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> with SingleTickerProviderStateMixin {
late TabController controller;
#override
void initState() {
super.initState();
controller = TabController(length: 2, vsync: this);
}
#override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text('TabBar Example'),
),
body: TabBarView(
children: <Widget>[FirstApp(), SecondApp()],
controller: controller,
),
bottomNavigationBar: TabBar(
controller: controller, // add here
tabs: [
Tab(icon: Icon(Icons.looks_one, color: Colors.blue),),
Tab(icon: Icon(Icons.looks_two, color: Colors.blue),),
],
)
);
}
#override
void dispose() {
controller.dispose();
super.dispose();
}
}
Since your field does not allow null values, but you cannot initialize your field when it's created, you have to declare it as late:
late TabController controller;
This allows you to assign a value later, but you will get an exception if you use it before it was assigned. The way your code looks, it should be okay.
It looks like you are using null safety in your project. So the dart is complaining about this line. Dart expects it to be initialized right after it was created:
TabController controller;
To fix the problem add the "late" keyword before TabController:
late TabController controller;
I'm trying to use url_launcher so that through a button it takes me to the dialer of my phone to make a call. In android it works perfectly but when I run it in IOS it does not work, it does nothing, I don't know if something is missing in the code, I appreciate your help
This is the code I am using:
import 'dart:io';
import 'package:flutter/material.dart';
import 'package:url_launcher/url_launcher.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(
primarySwatch: Colors.blue,
visualDensity: VisualDensity.adaptivePlatformDensity,
),
home: MyHomePage(title: 'Flutter Demo Home Page'),
);
}
}
class MyHomePage extends StatefulWidget {
MyHomePage({Key key, this.title}) : super(key: key);
final String title;
#override
_MyHomePageState createState() => _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> {
final String _phoneNumber = '318654378';
#override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text(widget.title),
),
body: Center(
child: RaisedButton(
child: Text('Call Number'),
onPressed: () {
if (Platform.isAndroid) {
// _callNumber();
launch('tel://$_phoneNumber');
} else if (Platform.isIOS) {
launch('tel://$_phoneNumber');
}
}),
),
);
}
}
Any idea what is going on
