Opening Location Permission from the inside of App flutter

Using Geolocator Package, you can open location settings as following. Please note that is will only open the device Location page, not the App permission manager.

Geolocator.openLocationSettings();

Use this package called, permission_handler. This will allow you to open the app settings page where you can find the location permission.

usage:

RaisedButton(
            onPressed: () =>  openAppSettings(),
            child: Text("Open app settings"),
          ),

In GeoLocation Package use Geolocator.openAppSettings();

Like that

AlertDialog(
            actions: [
              CupertinoDialogAction(
                child: Text('Back'),
                onPressed: () {
                  if (Platform.isIOS) {
                    exit(0);
                  } else {
                    SystemNavigator.pop();
                  }
                },
              ),
              CupertinoDialogAction(
                child: Text('Settings'),
                onPressed: () {
                  Geolocator.openAppSettings();
