[Bug] Geolocator.requestPermission() doesn't return (Android API 28)

[yoniker]

🐛 Bug Report

At Android API 30,everything is working fine all of the time. At android API 28 (I test this dozens of times): About half of the time, requestPermission works, but at the other half,Geolocator.requestPermission() doesn't return not shows anything to the user. Curiously, when the app state changes and upon resuming, it suddenly decides to ask the user for a permission (In some tests I have waited 2 minutes before putting the app in the background,so it isn't about time). See https://youtube.com/shorts/j60CfVZDsyE?feature=share

Expected behavior

Ask permissions from the user all of the time (and not half of the time)? :D

Reproduction steps

Call Geolocator.requestPermission() on an Android API 28 emulator. Possibly not working on other Android APIs (didn't test), note that on android 30 it is working all of the time.

Configuration

Version: 9.0.1

Platform:

• [ ] :iphone: iOS

Dear @yoniker,

It would help a lot if you could supply us with an output of flutter doctor -v. Furthermore, can you send us some minimal required code to reproduce this issue. Also, be aware that testing on simulators could also trigger some unusual behaviour.

Add a description of detailed steps to reproduce, expected and current behaviour, logs and the output of 'flutter doctor -v'. Thanks for your contribution.

Here's the output of flutter doctor -v

Here's the function where I'm calling the Geolocator.requestPermission() method:

` static Future<Position> determinePosition() async { bool serviceEnabled; LocationPermission permission; Position? position;

serviceEnabled = await Geolocator.isLocationServiceEnabled();
if (!serviceEnabled) {
  await Geolocator.openLocationSettings();
}

permission = await Geolocator.checkPermission();

debugPrint('Permission???$permission');

if (permission == LocationPermission.denied &&
    permission != LocationPermission.deniedForever) {
  debugPrint('before permission');
  permission = await Geolocator.requestPermission();
  debugPrint('Permission???$permission');
  if (permission == LocationPermission.whileInUse ||
      permission == LocationPermission.always) {
    position = await Geolocator.getCurrentPosition();
  }
} else {
  if (permission != LocationPermission.deniedForever)
    position = await Geolocator.getCurrentPosition();
}

return position!;

}`

In above function the flow gets stuck at permission = await Geolocator.requestPermission();, & it never returns anything at all

Further, I'm facing this issue on a real device itself not any simulator

I am currently facing the same issue, when run on an emulator it works fine but it doesn't work on a real device.
