I'm trying to get the coordinations of a String address using Geocoder, my code is working well on ios devices but when I run it on Android it shows me this error

Here is my code
return TextField(
controller: textEditController,
onTap: () async {
p = await PlacesAutocomplete.show(
context: context,
apiKey: R.Google_api_key,
language: "fr",
components: [Component(Component.country, "fr")]);
textEditController.text = p.description;
var addresses = await Geocoder.local.findAddressesFromQuery(p.description);
schedule.UpdateListeners(addresses.first.coordinates.latitude,addresses.first.coordinates.longitude) ;
//final double distance = await distanceBetween( addresses.first.coordinates.latitude, addresses.first.coordinates.longitude, endLatitude, endLongitude);
},
decoration: InputDecoration(
border: InputBorder.none,
hintText: 'Adresse, ex. 5 Rue Thénard Paris'),
);
The place autocomplete is working well and returning the required address.
There can be many reasons of appearing this issue,
Negative Lat or lang
In emulator, it can throw exception while in real device not
Problem with api
Some people recommend to use Geocoder.google instead of Geocoder.local [Link for discussion this problem in github][1]
The problem seems to be related to the configuration of the emulator, when I tried the same program on another emulator it worked very well, I have tried to delete the emulator and install it again and the problem is solved !

Although this is not recommended in production scenarios, you can accept any certificates by overriding the HttpClient that dio uses by providing a onHttpClientCreate, like the following :
(dio.httpClientAdapter as DefaultHttpClientAdapter).onHttpClientCreate = (client) {
client.badCertificateCallback=(X509Certificate cert, String host, int port){
return true;
};
};
Again, only use this for debugging and development purposes. In production, you should use a valid SSL certificate.
Documentation for onHttpClientCreate

Any thoughts?
I found the error, I don't know why but it works deleting the async function. So, the result it's:
launchUrl(url) {
launch(url);
}
On iOS it works with the async flavour, but not on Android.
From API30 (Android 11) onwards, your Android app has to list all apps it interacts with.
Add this in your android manifest file (android > app > src > main > AndroidManifest.xml)
<uses-permission android:name="android.permission.QUERY_ALL_PACKAGES"/>
Install the package properly using the steps given here. You should add a dependency of url_launcher in pubspec.yaml file. If you have done that,
To solve this issue you should clean the project using flutter clean, and then you upgrade your flutter using flutter upgrade. This will solve the problem for sure. If not, you create a new project and then paste the code in it.
I am attempting to play a simple sound using flutter's audioplayers library. When I attempt to, I get an Unable to load asset error. I've gone through several related questions on this site, and all of them seem to only suggest checking the indentation on the pubspec.yaml file and running flutter clean. I have done this several times and have had no results. Flutter Doctor finds no issues.
When I click the button that should cause the sound to play, I receive this:

Here is the code that should play the audio file:
import 'package:audioplayers/audio_cache.dart';
import 'dart:async';
import 'package:audioplayers/audioplayers.dart';
AudioPlayer advancedPlayer;
AudioCache audioCache;
void initPlayer() {
advancedPlayer = AudioPlayer();
audioCache = AudioCache(fixedPlayer: advancedPlayer, prefix: 'sounds/');
}
Future<void> playSound(String path) async {
await audioCache.play(path);
return;
}
Here is where the methods are called:
void initState() {
super.initState();
initPlayer();
}
void startNewRoute() async {
await playSound('start.mp3');
// more code here
}
Here is the assets section of pubspec.yaml
flutter:
uses-material-design: true
assets:
- images/
- sounds/start.mp3
fonts:
- family: RobotoMono
fonts:
- asset: fonts/RobotoMono-Regular.ttf
- asset: fonts/RobotoMono-Bold.ttf
And the files are structured like this:
root
lib
[dart files]
images
[some images]
sounds
start.mp3
I can't find any discrepancies between what I've done here and the way the documentation of the library explains it should be used. Any help is appreciated, thanks.
As per by design, you should be adding "assets/" setting your pubspec.yaml like this:
assets:
- images/
- assets/sounds/start.mp3
Audio Cache official doc here
Don't forget to add these files to your pubspec.yaml file:
flutter: assets:
assets/explosion.mp3

Any suggestion on what's going wrong in this
i have added the following plugin also – #Neelay Srivastava
MissingPluginException
what ever plugin you add it is not integrated in app although the plugin is get by pub
but not interacted in app for that you just have to quit app and build again
