Creating a share class Flutter - flutter

Question

I am not sure if this is possible, but with SwiftUI I have a mediaplayer class which has all my media player controls in it.
I am wondering if it is possible to have a flutter class file that hold flutter_radio_player and 1 media player that can change audio source?
The issue I have ran into with our old android app is we can't change the track without it creating a whole new media player.
I can't find any sample code on how to do this.
My code currently:
import 'package:flutter/material.dart';
import 'dart:async';
import 'package:flutter/services.dart';
import 'package:flutter_radio_player/flutter_radio_player.dart';
void main() => runApp(MyApp());
class MyApp extends StatefulWidget {
var playerState = FlutterRadioPlayer.flutter_radio_paused;
var volume = 0.8;
#override
_MyAppState createState() => _MyAppState();
}
class _MyAppState extends State<MyApp> {
int _currentIndex = 0;
final List<Widget> _children = [
new MyApp(),
];
FlutterRadioPlayer _flutterRadioPlayer = new FlutterRadioPlayer();
#override
void initState() {
super.initState();
initRadioService();
}
Future<void> initRadioService() async {
try {
await _flutterRadioPlayer.init(
"DRN1", "Live", "http://stream.radiomedia.com.au:8003/stream", "false");
} on PlatformException {
print("Exception occurred while trying to register the services.");
}
}
#override
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
appBar: AppBar(
title: const Text('Flutter Radio Player Example'),
),
body: Center(
child: Column(
children: <Widget>[
StreamBuilder(
stream: _flutterRadioPlayer.isPlayingStream,
initialData: widget.playerState,
builder:
(BuildContext context, AsyncSnapshot<String> snapshot) {
String returnData = snapshot.data;
print("object data: " + returnData);
switch (returnData) {
case FlutterRadioPlayer.flutter_radio_stopped:
return RaisedButton(
child: Text("Start listening now"),
onPressed: () async {
await initRadioService();
});
break;
case FlutterRadioPlayer.flutter_radio_loading:
return Text("Loading stream...");
case FlutterRadioPlayer.flutter_radio_error:
return RaisedButton(
child: Text("Retry ?"),
onPressed: () async {
await initRadioService();
});
break;
default:
return Row(
crossAxisAlignment: CrossAxisAlignment.center,
mainAxisAlignment: MainAxisAlignment.center,
children: <Widget>[
IconButton(
onPressed: () async {
print("button press data: " +
snapshot.data.toString());
await _flutterRadioPlayer.playOrPause();
},
icon: snapshot.data ==
FlutterRadioPlayer
.flutter_radio_playing
? Icon(Icons.pause)
: Icon(Icons.play_arrow)),
IconButton(
onPressed: () async {
await _flutterRadioPlayer.stop();
},
icon: Icon(Icons.stop))
]);
break;
}
}),
Slider(
value: widget.volume,
min: 0,
max: 1.0,
onChanged: (value) => setState(() {
widget.volume = value;
_flutterRadioPlayer.setVolume(widget.volume);
})),
Text("Volume: " + (widget.volume * 100).toStringAsFixed(0))
],
),
),
),
);
}
}

FlutterRadioPlayer Author here. With the new release of the player, you can do this.
You just have to call
_flutterRadioPlayer.setUrl('URL_HERE')
The player will automatically set the old stream to a halt and start the new stream. Yes, you can set it to autoplay when ready as well. Just refer to the docs in new release.
