fix: downgraded some dependencies to re-introduce compatbility with Flutter 3.19

Slightly downgraded package dependencies so that it works in flutter 3.19.

Thanks again :) However, I'm just wondering whether we should bump the minimum SDK version to 3.19, or further downgrade the depedency constraints, because I guess this could still cause issues for those on a version prior to 3.19.

@JaffaKetchup The idea for a public package like flutter_map would be to let the user configurations decide what is best by using low version numbers and the ^ syntax, except for versions that are really needed (e.g. bug fixes) or versions that are highly recommended (e.g. latlong2: ^0.9.1)
That would mean sort of rollbacking your previous pubspec.yaml, right?

This is fine for now, we can downgrade all the dependencies to their latest major version (or later if we need functionality in a minor/patch) later. Thanks 👍
