Request Permissions Again After User Denies Location Services

Request permissions again after user denies location services?

The OS will only ever prompt the user once. If they deny permission, that's it. What you can do is direct the user to the Settings for your app by passing UIApplicationOpenSettingsURLString to UIApplication's openURL: method. From there, they can re-enable location services if they wish. That said, you probably shouldn't be too aggressive about bugging them for the permission.

Flutter - Re ask location permission after denied

you could wrap your initPlatformState() in a setState in initState

      @override
void initState() { 
  super.initState();
  setState(() {
     initPlatformState()
  });

}

How to ask permission (RunTime) again if the user deny for the first time swift

When you discover that location is denied, you only can open app settings
here is example of alert with that

let alertController = UIAlertController (title: "Title", message: "Go to Settings?", preferredStyle: .alert)

    let settingsAction = UIAlertAction(title: "Settings", style: .default) { (_) -> Void in
        guard let settingsUrl = URL(string: UIApplicationOpenSettingsURLString) else {
            return
        }

        if UIApplication.shared.canOpenURL(settingsUrl) {
            UIApplication.shared.open(settingsUrl, completionHandler: { (success) in
                print("Settings opened: \(success)") // Prints true
            })
        }
    }
    alertController.addAction(settingsAction)
    let cancelAction = UIAlertAction(title: "Cancel", style: .default, handler: nil)
    alertController.addAction(cancelAction)

    present(alertController, animated: true, completion: nil)

flutter location permissions prompt not appearing

Since version 8.0.0 of the geolocator plugin, the implicit requesting of permissions when calling the Geolocator.getCurrentPosition() or Geolocator.getPositionStream() methods have been removed. Starting from version 8.0.0 it is necessary to explicitly call the Geolocator.requestPermission() method before calling the Geolocator.getCurrentPosition() or Geolocator.getPositionStream() methods.

The suggested flow looks something like this:

Future<Position> getLocation() {
  // Test if location services are enabled.
  bool serviceEnabled = await Geolocator.isLocationServiceEnabled();
  if (!serviceEnabled) {
    // Location services are not enabled don't continue
    // accessing the position and request users of the 
    // App to enable the location services.
    return Future.error('Location services are disabled.');
  }

  LocationPermission permission = await Geolocator.checkPermission();
  if (permission == LocationPermission.denied) {
    permission = await Geolocator.requestPermission();
    if (permission == LocationPermission.deniedForever) {
      // Permissions are denied forever, handle appropriately. 
      return Future.error(Exception('Location permissions are permanently denied.'));
    } 

    if (permission == LocationPermission.denied) {
      // Permissions are denied, next time you could try
      // requesting permissions again (this is also where
      // Android's shouldShowRequestPermissionRationale 
      // returned true. According to Android guidelines
      // your App should show an explanatory UI now.
      return Future.error(Exception('Location permissions are denied.'));
    }
  }

  // When we reach here, permissions are granted and we can
  // continue accessing the position of the device.
  return await Geolocator.getCurrentPosition();
}
