what do i do to fix this?
I got this error and I did the same thing but I found the solution :
You need to use
audioplayers:^1.0.1
then if you want to play an asset audio
just type:
final audio2= AudioPlayer();
audio2.play(AssetSource('Your wav file or your mp3 file '));
and thats it and it will work perfectly:).
It is because of the recent update of the package, the solution is: use audioplayers as package & AudioPlayer() as constructor & this method play(AssetSource('')) .

I have this code below which plays a sound every time I hit a button.
AudioPlayer player = AudioPlayer();
Future<void> playSound({required String soundStr}) async {
player.setAsset(soundStr);
player.play();
}
But whenever I hit the button fast, sometimes it will show this error. How can I eliminate this error? I tried adding player.stop(); but it still the same.

Edit: I tried adding await.
Future<void> playSound({required String soundStr}) async {
await player.setAsset(soundStr);
await player.play();
}
If I hit the buttons fast, it will still have error. Though it is now different.

Both setAsset and play are future method, you can await for setting assets
Future<void> playSound({required String soundStr}) async {
await player.setAsset(soundStr);
await player.play();
}
I have my flutter App integrated with firebase, everything was fine but after i integrate firebase i got error whenever I try to run my app.
My main method looks like this:
Future<void> main() async {
WidgetsFlutterBinding.ensureInitialized();
await Firebase.initializeApp(
options: DefaultFirebaseOptions.currentPlatform,
);
runApp(child: MyApp());
}

I had similar issue when create firebase app by flavors using flutterfire CLI. I realized that flutterfire create apps with same name in different projects. Then I tried 2 ways and it works.
1st: manually change app name in each firebase project.
2nd: add param name when initialize such as in main_dev.dart
Example:
await Firebase.initializeApp(
name: "dev-project",
options: DefaultFirebaseOptions.currentPlatform);
I used the same name used in the firebase console as my project ID for consistency, keep in mind that you cannot add spaces to the name (only dashes -).
i already initialized awesome_notifications plugin in main.dart When i hot restart, in debug console i'm getting this error:

Here's my code :
main.dart
Future<void> main() async {
WidgetsFlutterBinding();
await Hive.initFlutter();
if (!Hive.isAdapterRegistered(AddEventModelAdapter().typeId)) {
Hive.registerAdapter(AddEventModelAdapter());
}
AwesomeNotifications()
.initialize('resource://drawable/res_notification_app_icon', [
NotificationChannel(
channelKey: 'schedule_channel',
channelName: 'scheduled_channel',
channelDescription: 'descroiption',
locked: true,
importance: NotificationImportance.High,
),
]);
runApp(const MyApp());
}
Whenever you add a plugin in your pubspec.yaml, you need to stop the app and re-run it again because the plugin contains native code on both platforms.
If it still does not work, then do flutter clean and run.

Current version of TestFairy plugin: testfairy: ^2.0.1
Flutter (Channel stable, 1.22.2)
Dart version 2.10.2.
Also, I've added analysis_options.yaml:
analyzer:
enable-experiment:
- non-nullable
I run the app with the command flutter run --enable-experiment=non-nullable --no-sound-null-safety.
How to resolve this error?
#Akif has pointed in the right direction of a reason for the problem. In fact, this was due to the local_notifications plugin. I managed to solve this problem by switching the flutter to the beta channel (Flutter 1.23.0-18.1.pre • channel beta).
I'm using this connectivity plugin to check the internet connectivity status. It works fine with the flutter dart code but when I called the flutter dart code from native android kotlin code this missingplugin exception occurs. So for me this error occurs only when the flutter code is called from native android kotlin code using platform channel.

Any suggestions would be really helpful. Thanks in advance.
The connectivity plugin doesn't seem to require writing any platform-specific code. Have you tried running a restart after adding the plugin? A hot reload may have yet to include the plugin that you've added.
If you're still having issues, it's best to share a minimal repro for us to be able to better understand the issue.
