[PermissionRequestInProgressException] A request for permissions is already running

[MagdyEl-Sayed]

A request for permissions is already running, please wait for it to finish before doing another request (note that you can request multiple permissions at the same time).

[JDDV]

Hi @MagdyEl-Sayed, is it possible for you to share your code so I can see where this messages comes from? If you want to ask multiple permissions at the same time, you should request them as follow:

Map<Permission, PermissionStatus> statuses = await [
  Permission.location,
  Permission.storage,
].request();
print(statuses[Permission.location]);

I hope this helped you out, let me know if it worked!

[MagdyEl-Sayed]

if i select denied and request permission again , it return exception message "request for permissions is already running"

[JDDV]

Hi @MagdyEl-Sayed, can you share some more information please?

I would like to see a minimal code snippet to reproduce the issue and the flutter doctor -v output.

[matthias-steinkamp]

if i select denied and request permission again , it return exception message "request for permissions is already running"

same here, exception is thrown for the deny-case only.

final Permission _permission = Permission.locationWhenInUse;
final PermissionStatus status = await _permission.status;

if (!status.isLimited && !status.isGranted) {
  // Ask user for permission. If it has already been granted before, nothing happens
  final PermissionStatus result = await _permission.request();

  if (result.isPermanentlyDenied) {
    onPermanentlyDenied.call();
    return;
  }

  if (!result.isGranted) {
    return;
  }
}

onGranted.call();

flutter doctor -v

Maybe this will help someone ...

I had exactly same issue (IOS emulator only ) (Android works fine) I managed to finally fix this on IOS emulator side... Removed background permission for IOS in info.plist and only left this one: <key>NSLocationWhenInUseUsageDescription</key> <string>This app requires access to your location information to operate</string>

then finally cold run and i get the permissions dialog...select allow once or when using app and seems to be fine.

I experience the same bug although I'm requesting the same permission multiple times, e.g.

I defined a method which retrieves the location and checks if permission has been granted. I do this as I had crashes when requesting the location after running the permission request as a quick fix for now

Future<LocationData?> getLocation({LocationAccuracy accuracy = LocationAccuracy.high}) async {
    final granted = await ph.Permission.locationWhenInUse.isGranted;
    if (!granted) {
      final result = await ph.Permission.locationWhenInUse.request();
      Fimber.e('location has not been granted');
      return null;
    }
    final location = Location()..changeSettings(accuracy: accuracy);
    return location.getLocation();
}    

and in another place I try to update the location as fast as possible by running:

// Request one location precision after the other to reduce location update time
final lastKnownLocation = await getLocation(accuracy: LocationAccuracy.powerSave);
if (lastKnownLocation != null) {
   emit(OnLastKnownLocation(location: lastKnownLocation));
}

final normalLocation = await getLocation();
if (normalLocation != null) {
   emit(OnLocation(location: normalLocation));
}

final bestLocation = await getLocation(accuracy: LocationAccuracy.navigation);
if (bestLocation != null) {
   emit(OnLocation(location: bestLocation));
}

So somehow awaiting the permission response didn't really finish the request.

It might be not the best code but I guess it illustrates the problem quite well.

@MagdyEl-Sayed

I've experienced the same issue and found a solution. Did you override onRequestPermissionsResult in your MainActivity?

My fix is adding a fallback on a not managed requestCode like this snippet. Without the fallback, the PermissionManager.onRequestPermissionsResult is never called and the plugin is not updated about the permission result.

override fun onRequestPermissionsResult(
        requestCode: Int,
        permissions: Array<out String>,
        grantResults: IntArray
    ) {
        when (requestCode) {
            myRequestCode -> myFunction(myRequestCode)
            else -> super.onRequestPermissionsResult(requestCode, permissions, grantResults);
        }
    }

Probably related to: https://github.com/Baseflow/flutter-permission-handler/issues/783 and https://github.com/Baseflow/flutter-permission-handler/issues/581

[sonanis]

Same issue here.

flutter SDK 2.10.3 permission_handler: 10.2.0 or 11.0.1

device: Android 13

static Future<bool> locationGranted() async {
    bool isGranted = true;
    Map<Permission, PermissionStatus> statuses = await [
      Permission.location,
    ].request();
    statuses.forEach((key, permission) {
      if(permission.isDenied){
        isGranted = false;
      }
    });
    return isGranted;
  }

我也遇到了同样的问题，升级到11.0.1后作者解决了这个问题

Same issue here，and the problem was solved after upgrading to 11.0.1

Same issue here，and the problem was solved after upgrading to 11.0.1

Same issue. I try to update permission_handler: ^11.1.0 , still alive this problem.

i was facing same in fcm..i double checked we are not requesting permission more than once but is still facing this issue..however we are not facing crashes so I have left it open.. The issue probably is in new flutter version and a migration is needed.. we will do it later but until then the app works just fine..

Any suggestions are most welcome..
