AnimateCamera is broken with Flutter 3.27.0

[TBA-Lucas]

Now that mapbox_gl is able to compile to 3.27.0 (🎉🎉🎉), a new issue has cropped up with animateCamera:

Uncaught Error: Null check operator used on a null value
    at mapbox_web_gl_platform.dart:209:18
    at _wrapJsFunctionForAsync_closure.$protected (async_patch.dart:311:19)

    at _wrapJsFunctionForAsync_closure.call$2 (async_patch.dart:336:23)
    at Object._asyncStartSync (async_patch.dart:241:3)

Workaround: moveCamera still works.

Would be awesome to have this fixed (I have no idea how, maybe it has to do with the optional animation duration?), since the animation is a really awesome and neat part of the framework!

(Weirdly enough it only produces the error when in --release or --profile mode, not in --debug.)

I saw that there are supposedly some fixes in a fork of mapbox_gl for flutterflow, can't find the code for the changes though - but maybe that'll help narrowing the issue down:

https://pub.dev/packages/mapbox_gl_flutterflow/changelog

For the web version, the package is based on mapbox_gl_dart, which hasn't been updated recently. It uses the js package that should be replaced by dart:js_interop.

Recent Flutter versions have compatibility issues with the old js package, causing interoperability failures. I successfully fixed the bug by migrating from js to js_interop, referencing the implementation in Ocell-io/mapbox-gl-dart's new-js_interop (see issue #1428).

Without an official update, this package risks becoming deprecated in newer Flutter versions.
