Bug Description

When rebuilding the MapLibreMap widget a lot in a short amount of times the console shows JNI related exceptions.

E/flutter (26853): [ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: Bad state: Use after release error
E/flutter (26853): #0      JReference.pointer (package:jni/src/jreference.dart:56:21)
