Location Permission Status - always getting as denied in Flutter-CodePudding

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" />

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.
