• Fixed circles with only borders/filled with a transparent color

Thanks for getting on this so quickly :)
I'll have a look into it ASAP.

That doesn't quite look like a circle to me 😂! Did you forget something or is this not ready for review yet?

Oups sorry, fixed! @JaffaKetchup

LGTM, thanks for fixing this so quickly, we really do appreciate it!

I added an extra circle marker for testing as well. Dorney Lake is pretty much exactly 2.2km long, so it's useful to test radii and such like.

Hi

just tried the demo and the circle still does not fill correctly. When zooming it works partially.

Hi @algizmonaco,
I see you're running on iOS, can you try disabling Impeller to see if that resolves the issue?

[algizmonaco]

thx,

Disabling Impeller fixes the issue. keeping disabled until it is fixed. May you want to add this to readme. thx

I believe the fix is already available on Flutter's 'master' branch, so hopefully it won't take too long to arrive!
