I'm trying to Play a custom mp3 sound I've put in an asset folder into the app folder, like you would do for a font or an image file, but then I don't really know how to proceed. I think I might need to register the audio file into the pubspec.yaml, but how?
And how do I play it?
I've checked out this two answer:
How to play a custom sound in Flutter?
Flutter - Play custom sounds updated?
But the first one is too old and the second one uses URLs as the sound path: const kUrl2 = "http://www.rxlabz.com/labz/audio.mp3"; and the sound I like to play is in the app, not online. So... How can I do it?
This Is My Current Code, as You can see, there's only a Floating Button.
And I need To Start The Sound at the Point I stated it in the code.
But visual studio underlines in red Various Parts:
await: it says that await is unrecognized.
audioPlugin.play: is says It's also unrecognized
import 'dart:io';
import 'dart:typed_data';
import 'package:flutter/material.dart';
import 'package:flutter/services.dart';
void main() => runApp(new MyApp());
Directory tempDir = await getTemporaryDirectory();
File tempFile = new File('${tempDir.path}/demo.mp3');
await tempFile.writeAsBytes(bytes, flush: true);
AudioPlayer audioPlugin = new AudioPlayer();
class MyApp extends StatelessWidget {
#override
Widget build(BuildContext context) {
return new MaterialApp(
title: 'Flutter Demo',
theme: new ThemeData(
primarySwatch: Colors.blue,
),
home: new MyHomePage(title: 'Flutter Demo Home Page'),
);
}
}
class MyHomePage extends StatefulWidget {
MyHomePage({Key key, this.title}) : super(key: key);
final String title;
#override
_MyHomePageState createState() => new _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> {
void _incrementCounter() {
setState(() {
print("Button Pressed");
///
///
///
/// Here I Need To start Playing the Sound
///
///
///
///
audioPlugin.play(tempFile.uri.toString(), isLocal: true);
});
}
#override
Widget build(BuildContext context) {
return new Scaffold(
appBar: new AppBar(
title: new Text(widget.title),
),
body: new Center(),
floatingActionButton: new FloatingActionButton(
onPressed: _incrementCounter,
tooltip: 'Increment',
child: new Icon(Icons.add),
),
);
}
}
It's not pretty, but...
Add the mp3 file to the assets folder and add it to pubspec.yaml like this.
Load the asset as binary data with rootBundle.load(asset)
Use path_provider to get the app's temp folder location
Use regular dart:io to open a file in tempDir (maybe use the asset name) and write bytes to it.
Form a file URL from the temporary file name in the form file:///folderPath/fileName
Pass this to audioplayer, setting isLocal to true (needed on iOS).

await tempFile.writeAsBytes(data.buffer.asUint8List(), flush: true);
mp3Uri = tempFile.uri.toString();
print('finished loading, uri=$mp3Uri');
}

audioPlugin.play(mp3Uri, isLocal: true);

}
}
Use the audioplayers package => https://pub.dev/packages/audioplayers
Add the key to plist for iOS Support
<key>NSAppTransportSecurity</key>
<dict>
<key>NSAllowsArbitraryLoads</key>
<true/>
</dict>
Add dependencies to pubspec.yaml file
audioplayers: ^0.13.2
Flutter code:
import 'package:flutter/material.dart';
import 'package:audioplayers/audio_cache.dart';
import 'package:audioplayers/audioplayers.dart';
class AudioTest extends StatefulWidget {
#override
_AudioTestState createState() => _AudioTestState();
}
class _AudioTestState extends State<AudioTest> {
static AudioCache _player = AudioCache();
static const _audioPath = "count_down.mp3";
AudioPlayer _audioPlayer = AudioPlayer();
Future<AudioPlayer> playAudio() async {
return _player.play(_audioPath);
}
void _stop(){
if (_audioPlayer != null) {
_audioPlayer.stop();
}
#override
void initState() {
playAudio().then((player) {
_audioPlayer = player;
});
super.initState();
}
#override
Widget build(BuildContext context) {
return homeScreen();
}
Widget homeScreen() {
return Scaffold();
//Enter your code here

I run below code but it's not working for real
import 'package:flutter/material.dart';
import 'package:flutter_phone_direct_caller/flutter_phone_direct_caller.dart';
void main() {
runApp(const MyApp());
}
class MyApp extends StatelessWidget {
const MyApp({Key? key}) : super(key: key);
#override
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
body: Center(
child: RaisedButton(
onPressed: _callNumber,
child: Text('Call Number'),
),
),
));
}
}
_callNumber() async {
const number = '+82)010-7335-7424';
print("hi"); //set the number here
bool? res = await FlutterPhoneDirectCaller.callNumber(number);
}
how can i run for real???
Should I have to build apk and run in real phone..?
I think for call dialer or Direct navigate to the dialer, the best package will be url_launcher. At first please install the package & then try the below code ---
import 'package:flutter/material.dart';
import 'package:url_launcher/url_launcher.dart';
void main() {
runApp(const MyApp());
}
class MyApp extends StatelessWidget {
const MyApp({Key? key}) : super(key: key);
#override
Widget build(BuildContext context) {
return const MaterialApp(
home: Scaffold(
body: Center(
child: ElevatedButton(
onPressed: _callNumber,
child: Text('Call Number'),
),
),
));
}
}
_callNumber() async {
const number = '+82)010-7335-7424';
print("hi"); //set the number here
if (!await launchUrl(Uri.parse("tel://$number"))) throw 'Could not launch ${Uri.parse("tel://$number")}';
}
Basically, I change the code inside the _callnumber method which is
_callNumber() async {
const number = '+82)010-7335-7424';
print("hi"); //set the number here
if (!await launchUrl(Uri.parse("tel://$number"))) throw 'Could not launch ${Uri.parse("tel://$number")}';
}

Please help me go through it.
String text = "Hello World !! Hey There";
String url = "https://wa.me/?text=${Uri.encodeFull(text)}";
if (await canLaunchUrl(Uri.parse(url))) {
await launchUrl(Uri.parse(url),
mode: LaunchMode.externalApplication);
}
First, add url_launcher, then I use this code to launch whatsapp on flutter webview and works.
WebView(
initialUrl: getUrl(_url),
javascriptMode: JavascriptMode.unrestricted,
navigationDelegate: (NavigationRequest request) async {
if (request.url
.startsWith('https://api.whatsapp.com/send?phone')) {
print('blocking navigation to $request}');
List<String> urlSplitted = request.url.split("&text=");
String phone = "0123456789";
String message =
urlSplitted.last.toString().replaceAll("%20", " ");
await _launchURL(
"https://wa.me/$phone/?text=${Uri.parse(message)}");
return NavigationDecision.prevent;
}
print('allowing navigation to $request');
return NavigationDecision.navigate;
},
)
_launchURL(String url) async {
if (await canLaunch(url)) {
await launch(url);
} else {
throw 'Could not launch $url';
}
}
You can use url_launcher to launch URLs.
You can give https://api.whatsapp.com/send/?phone=(phone_number) URL to launch.
For the launching the WhatsApp Website use launch('https://api.whatsapp.com/send/?phone=(phone_number)')
Make sure you give your country code without (+).

thank you
stt.SpeechToText _speech;
You have to initialize this property or make it nullable as below
stt.SpeechToText? _speech;
I want to create a RIVE animation with flutter. I followed a tutorial in YouTube. I wrote the same thing but when I execute two errors is displayed

Control playing and pausing a looping animation:
import 'package:flutter/material.dart';
import 'package:rive/rive.dart';
class PlayPauseAnimation extends StatefulWidget {
const PlayPauseAnimation({Key? key}) : super(key: key);
#override
_PlayPauseAnimationState createState() => _PlayPauseAnimationState();
}
class _PlayPauseAnimationState extends State<PlayPauseAnimation> {
// Controller for playback
late RiveAnimationController _controller;
// Toggles between play and pause animation states
void _togglePlay() =>
setState(() => _controller.isActive = !_controller.isActive);
/// Tracks if the animation is playing by whether controller is running
bool get isPlaying => _controller.isActive;
#override
void initState() {
super.initState();
_controller = SimpleAnimation('idle');
}
#override
Widget build(BuildContext context) {
return Scaffold(
body: Center(
child: RiveAnimation.network(
'https://cdn.rive.app/animations/vehicles.riv',
controllers: [_controller],
// Update the play state when the widget's initialized
onInit: () => setState(() {}),
),
),
floatingActionButton: FloatingActionButton(
onPressed: _togglePlay,
tooltip: isPlaying ? 'Pause' : 'Play',
child: Icon(
isPlaying ? Icons.pause : Icons.play_arrow,
),
),
);
}
}
To play an animation from an asset bundle, use:
RiveAnimation.asset('assets/vehicles.riv'
in place of
RiveAnimation.network('https://cdn.rive.app/animations/vehicles.riv',
This line:
_controller = SimpleAnimation('idle');
attempts to play an animation called 'idle'. If your animation is named differently, try replacing the name here.
I am new to Flutter. I want to get the text along with its source. Currently, I am using receive_sharing_intent which is serving the purpose of TextStream and Url individually.
I want to share the copied text from the browser and keep its URL along with it.
I followed this doc hence my main.dart is same as:
import 'package:flutter/material.dart';
import 'dart:async';
import 'package:receive_sharing_intent/receive_sharing_intent.dart';
void main() => runApp(MyApp());
class MyApp extends StatefulWidget {
#override
_MyAppState createState() => _MyAppState();
}
class _MyAppState extends State<MyApp> {
StreamSubscription _intentDataStreamSubscription;
List<SharedMediaFile> _sharedFiles;
String _sharedText;
#override
void initState() {
super.initState();
// For sharing or opening urls/text coming from outside the app while the app is in the memory
_intentDataStreamSubscription =
ReceiveSharingIntent.getTextStream().listen((String value) {
setState(() {
_sharedText = value;
});
}, onError: (err) {
print("getLinkStream error: $err");
});
// For sharing or opening urls/text coming from outside the app while the app is closed
ReceiveSharingIntent.getInitialText().then((String value) {
setState(() {
_sharedText = value;
});
});
}
#override
void dispose() {
_intentDataStreamSubscription.cancel();
super.dispose();
}
#override
Widget build(BuildContext context) {
const textStyleBold = const TextStyle(fontWeight: FontWeight.bold);
return MaterialApp(
home: Scaffold(
appBar: AppBar(
title: const Text('Plugin example app'),
),
body: Center(
child: Column(
children: <Widget>[
Text("Shared files:", style: textStyleBold),
Text(_sharedFiles?.map((f)=> f.path)?.join(",") ?? ""),
SizedBox(height: 100),
Text("Shared urls/text:", style: textStyleBold),
Text(_sharedText ?? "")
],
),
),
),
);
}
}
Any suggestions on how to proceed to this or any Reference will work.
Thanks!!
