Exception thrown after calling `dispose()` on MapboxMap

Environment

• Flutter version: 3.16.9
• mapbox_maps_flutter version: 0.5.1
• Device: iPhone Simulator
• OS: iOS 17.2

Steps to Reproduce

  Code: GitHub Gist

Description

I'm encountering an issue where an exception is thrown after exiting a screen and calling dispose() on MapboxMap. The exception message suggests that the MapboxMap object is being used after being disposed.

Expected Behavior

After calling dispose() on a MapboxMap object, the object is disposed of properly and no exception is thrown.

Actual Behavior

The following exception is thrown:

[ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: A MapboxMap was used after being disposed.
Once you have called dispose() on a MapboxMap, it can no longer be used.

Beginne damit, die Freigabepfade in src/mapbox_maps_flutter/src/mapbox_map.dart und src/mapbox_maps_flutter/src/map_widget.dart zu lesen, und verwende die verknüpften Reproduktionsschritte und das Gist, um den Fehler zu reproduzieren. Als erledigt gilt die Aufgabe, wenn ein Bildschirm mit MapWidget verlassen und dessen MapboxMap freigegeben werden kann, ohne dass die gemeldete use-after-dispose-Ausnahme auftritt.
