Hey there @vividos! Thank you so much for your PR! Someone from the team will get assigned to your PR shortly and we'll get it reviewed.

-		static LocationManager LocationManager =>
+		static LocationManager? LocationManager =>


I'm not sure if LocationManager can ever be null on a sane Android environment, but there might be some weird custom ROMs; I guess the best is to throw FeatureNotSupportedException then...

@jfversluis there are still my three questions...

vividos · 2023-02-15T21:39:58Z

src/Essentials/src/Geolocation/Geolocation.android.cs

 		{
+			if (provider == null)


as ILocationListener has the provider parameter marked with string?, provider may theoretically be null, but from reading the Android documentation, it makes no sense to be null. Therefore I just return here.

@jfversluis the second...

@@ -183,7 +185,7 @@ public void StopListeningForeground()
 				listener.ErrorHandler = null;
 			}

-			listeningManager.Delegate = null;
+			listeningManager.WeakDelegate = null;


I'm not sure setting the WeakDelegate is the proper thing to do here, but since the Delegate now is non-nullable, it can't be set to null anymore.

@jfversluis the third...

@jfversluis Here's the rest of the changes I mentioned. I added some comments to the changes that we should discuss.

@mandel-macaque Thanks for the review comments! I addressed all apart from two; see my above comments. Also I have three original comments attached to the code, which we also should discuss.

Amazing @vividos thank you! If you're looking for something after this... We might want to enable nullable on the project level and then add #nullable disable to the files that we still need to cover and remove #nullable enable for the ones that are already done.

Besides the other feedback there is these build errors:

/Users/builder/azdo/_work/2/s/src/Essentials/src/Geolocation/Geolocation.tizen.cs(16,25): error CS8613: Nullability of reference types in return type of 'Task GeolocationImplementation.GetLastKnownLocationAsync()' doesn't match implicitly implemented member 'Task<Location?> IGeolocation.GetLastKnownLocationAsync()'.

I'll check out the Tizen build error.
All of my pull requests have the purpose to make a (distant) future migration of my Forms projects to MAUI easier 😉

jfversluis · 2023-02-16T12:57:32Z

Hey I don't blame you! I can only be happy that you not only help yourself out, but also others in the process. So thank you for doing this!

mandel-macaque

Agree on the ones left as they where, there is a missing comment to be address (probably github hide it by mistake).

@vividos I took the liberty to do a commit fixing some forgotten == null and != null.

I think the rest of your comments are valid, so LGTM! Thank you!

Ah sorry I didn't see you comment. Sorry for the noise!
