Will you support play-services-location v21?

With the update to flutter_background_geolocation: ^4.8.7, at runtime, the app crashes with the following exception:

I tried bumping googlePlayServicesLocationVersion to v21.0.1, but then I get a compile time message:

"background-geolocation requires a maximum googlePlayServicesLocationVersion of 20.0.0 due to breaking changes in v21. googlePlayServicesLocationVersion has been overridden to 20.0.0"

Pegging to v20.0.0 makes this plugin incompatible with another (flutter_map_location_marker: 5.1.0+1) I am using because it references the geolocator plugin (v9.0.2), which uses v21.0.1.

I reverted to flutter_map_location_marker v5.0.0+1, which references geolocator v9.0.1 and now my app runs.

There was a breaking change fixed in v21.0.1, as mentioned here: https://developers.google.com/android/guides/releases#october_13_2022.

Perhaps this fixes the breaking change you refer to in the compile-time message?

Awesome, thanks!

The CHANGELOG has a mistake. The next major release for the flutter version will be 4.9.0 with v21.
