A basic code to get you started on creating a music player app in Flutter:
import ‘package:flutter/material.dart’;
import ‘package:audioplayer/audioplayer.dart’;
class MusicPlayerApp extends StatefulWidget {
@override
_MusicPlayerAppState createState() => _MusicPlayerAppState();
}
class _MusicPlayerAppState extends State<MusicPlayerApp> {
AudioPlayer audioPlayer;
bool isPlaying = false;
@override
void initState() {
super.initState();
audioPlayer = AudioPlayer();
}
void play() {
audioPlayer.play(“YOUR_AUDIO_FILE_URL”);
setState(() {
isPlaying = true;
});
}
void pause() {
audioPlayer.pause();
setState(() {
isPlaying = false;
});
}
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text(“Music Player App”),
),
body: Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: [
Text(“Song Title”),
SizedBox(height: 20),
isPlaying
? IconButton(
icon: Icon(Icons.pause),
onPressed: pause,
)
: IconButton(
icon: Icon(Icons.play_arrow),
onPressed: play,
),
],
),
),
);
}
}
In the code above, the AudioPlayer class from the audioplayer package is used to play an audio file. The play and pause methods are used to start and stop playback, respectively. The isPlaying state variable is used to keep track of the current playback state, and to display the appropriate play/pause button. Note that you will need to replace YOUR_AUDIO_FILE_URL with the actual URL for your audio file.
This code provides a basic starting point for a music player app, but there is a lot of room for improvement. For example, you may want to add the ability to play a playlist of songs, display album art and song information, and provide additional controls such as skip, rewind, and fast forward. Additionally, you may want to store information about the user’s playlists and playback progress locally on the device, so that the app can work offline.
