im using permission_handle to take permission for location.
and it always saying "No permissions found in manifest"
even i tried "flutter clean"
import 'package:permission_handler/permission_handler.dart';
class PermissionsService {
final PermissionHandler _permissionHandler = PermissionHandler();
Future<bool> _requestPermission(PermissionGroup permission) async {
var result = await _permissionHandler.requestPermissions([permission]);
if (result[permission] == PermissionStatus.granted) {
print('innnn');
return true;
}
return false;
}
Future<bool> requestLocationPermission({Function onPermissionDenied} ) async {
// return _requestPermission(PermissionGroup.locationWhenInUse);
var granted = await _requestPermission(PermissionGroup.location );
if(!granted){
onPermissionDenied();
}
return granted;
}
}
my Manifest.xml file
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.artistry">
<!-- Flutter needs it to communicate with the running application
to allow setting breakpoints, to provide hot reload, etc.
-->
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-permission android:name="android.permission.INTERNET"/>
</manifest>
You added permission in the Wrong Manifest File, You have to add location permission inside Android Manifest of this Directory android\app\src\main\AndroidManifest
You need to set permissions in main AndroidManifest.xml.
There are three folders debug, main and profile.
Run flutter clean.
See my example:
.../main/AndoridManifest.xml
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="test.packange.name">
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<!-- io.flutter.app.FlutterApplication is an android.app.Application that
calls FlutterMain.startInitialization(this); in its onCreate method.
In most cases you can leave this as-is, but you if you want to provide
additional functionality it is fine to subclass or reimplement
FlutterApplication and put your custom class here. -->

I have created below method to check the location permission status in my flutter application:
Future<void> checkLocationPermission(
BuildContext context, UserCredential userCredential) async {
locationPermissionStatus = await permission_status.Permission.location
.request()
.then((value) async {
if (locationPermissionStatus.isGranted) {
displayToast("granted");
await getCurrentLocation(context, userCredential);
} else {
displayToast("not granted");
}
return locationPermissionStatus;
});
}
Where, PermissionStatus is declared as below:
permission_status.PermissionStatus locationPermissionStatus =
permission_status.PermissionStatus.denied;
Imports as below:
import 'package:location/location.dart';
import 'package:permission_handler/permission_handler.dart' as permission_status;
Used below plugins:
permission_handler: ^10.2.0
location: ^4.4.0
But In App, When Location Permission pops up, I am tapping on option "While Using the App"
But I am always getting the toast display as "not granted"
What might be the issue? Thanks in Advance.
EDIT:
Already added below permissions for Android:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.mypackage">
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.CAMERA"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_BACKGROUND_LOCATION" />
</manifest>
Adding to the #Romil Mavani answer, you first have to add permissions in AndroidManifest:
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
But it also seems that you are using async/await with the combination of then which is very error-prone. You should either use one or the other.
Future<void> checkLocationPermission(
BuildContext context, UserCredential userCredential) async {
locationPermissionStatus =
await permission_status.Permission.location.request();
if (locationPermissionStatus.isGranted) {
displayToast("granted");
await getCurrentLocation(context, userCredential);
} else {
displayToast("not granted");
}
}
You have to add permission in manifest.
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
Like this : https://i.stack.imgur.com/PgdNF.png
Also permission status is not working correctly for only location permission so you have check and request permission using location package and it will works fine.
I Hope this things are solve your issue.
If you're using a Windows Emulator
I've faced the same issue before, but when I opened the application setting of my mobile's emulator to confirm, the location permission was not granted (off).
So, I granted it manually from the app settings.
Emulator: Setting/apps/allApps/myApp/permisson
This solution works for me.
i was trying to make upload features, so users can upload file into firebase account
in the past, it run well, but yesterday, it wont show the files
there is the code
uploadImage() async {
final storage = FirebaseStorage.instance;
final picker = ImagePicker();
PickedFile? image;
//Check Permissions
await Permission.photos.request();
var permissionStatus = await Permission.photos.status;
if (permissionStatus.isGranted) {
//Select Image
image = await picker.getImage(source: ImageSource.gallery);
var file = File(image!.path);
final fileName = basename(file.path);
final destination = 'user/$emaila/identitas/$fileName';
if (image != null) {
//Upload to Firebase
var snapshot = await storage
.ref()
.child(destination)
.putFile(file)
.whenComplete(() => null);
var downloadUrl = await snapshot.ref.getDownloadURL();
setState(() {
imageUrlidentitas = downloadUrl;
});
} else {
print('No Path Received');
}
} else {
print('Grant Permissions and try again');
}
}
here is android manifest

D/permissions_handler( 9318): No permissions found in manifest for: []9
I/flutter ( 9318): Grant Permissions and try again
how to solve this ? anyone know ?
i try looking in stackoverflow, but none of them are explain the answer
This is a recent bug which was introduced by the new version of the permissionhandler in 10.2.0. It is discussed here https://github.com/Baseflow/flutter-permission-handler/issues/944 and I will copy the answer to this question as well. This solution was also working for me.
I've fixed this by checking for Permissions.storage.status when the device is Android 12.0 or below, else I use the Permissions.photos.status. I use the device_info_plus plugin to check the Android version:
I added the following to my AndroidManifest.kt
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"
android:maxSdkVersion="32"/>
<uses-permission android:name="android.permission.READ_MEDIA_IMAGES"/>
and in flutter:
if (Platform.isAndroid) {
final androidInfo = await DeviceInfoPlugin().androidInfo;
if (androidInfo.version.sdkInt <= 32) {
/// use [Permissions.storage.status]
} else {
/// use [Permissions.photos.status]
}
}

Check your targetSdkVersion in build.gradle file.
If you are using targetSdkVersion = 30, you will need to write storage permission in a different way. I think you can try the solution discussed in this post
Flutter/ This is my code for creating folder using pathProdiver package
note: i have set the permission in manifest file as a
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
I do not what is the real problem here, the compiler says permission is denied but i set all the permissions.
Future<String> askForPermission() async {
final folderName = "newcreatefoldr";
final path = Directory("storage/emulated/0/$folderName");
var status=await Permission.storage.status;
if(!status.isGranted){
await Permission.storage.request();
}
if(await path.exists()){
return path.path;
}else{
path.create();
return path.path;
}
}
and the error saying ....
E/flutter (24174): [ERROR:flutter/lib/ui/ui_dart_state.cc(198)] Unhandled Exception: FileSystemException: Creation failed, path = 'storage/emulated/0/newcreatefoldr' (OS Error: Operation not permitted, errno = 1)

I solved this problem with the following solutions: For android 10/Q, I have added this permission in the androidManifest.xml:
<uses-permission android:name="android.permission.ACCESS_MEDIA_LOCATION"/>
and add this line in application tag:
android:requestLegacyExternalStorage="true"
like this:
<application
...
android:requestLegacyExternalStorage="true">
For android 11/R, add this permission:
<uses-permission android:name="android.permission.MANAGE_EXTERNAL_STORAGE"
tools:ignore="ScopedStorage" />
In app-user permission handler I'm checking permissions with the following function:
Future<bool> _hasAcceptedPermissions() async {
if (Platform.isAndroid) {
if (await _requestPermission(Permission.storage) &&
// access media location needed for android 10/Q
await _requestPermission(Permission.accessMediaLocation) &&
// manage external storage needed for android 11/R
await _requestPermission(Permission.manageExternalStorage)) {
return true;
} else {
return false;
}
}
if (Platform.isIOS) {
if (await _requestPermission(Permission.photos)) {
return true;
} else {
return false;
}
} else {
// not android or ios
return false;
}}

thank you
I tried all packages to send email ( flutter_email_sender - flutter_mailer -url_launcher), copy and paste the example, but always the same error message : " MissingPluginException(No implementation found for methode ...), I serach a simple example to send email on press button.
thank you
To use latest version of url_launcher or above version of 4.1.0+1
, you have to migrate to android x.
[https://flutter.dev/docs/development/packages-and-plugins/androidx-compatibility][1]
Example:
import 'package:flutter/material.dart';
import 'package:url_launcher/url_launcher.dart';
class SendEmail extends StatelessWidget {
void _contact() async {
final url = 'mailto:dude#gmail.com';
if (await canLaunch(url)) {
await launch(url);
} else {
throw 'Could not launch $url';
}
}
#override
Widget build(BuildContext context) {
return RaisedButton(
onPressed: (){_contact()},
child: Text('Mail'),
),
}
}
try adding these lines on AndroidManifest.xml
<!-- Provide required visibility configuration for API level 30 and above -->
<queries>
<!-- If your app checks for SMS support -->
<intent>
<action android:name="android.intent.action.VIEW" />
<data android:scheme="sms" />
</intent>
<!-- If your app checks for call support -->
<intent>
<action android:name="android.intent.action.VIEW" />
<data android:scheme="tel" />
</intent>
</queries>
then run flutter clean, then build again
it work for me but this is specific for url_launcher
