[Android] AnnotationManager seem to create duplicate annotation's ids

[ankiimation]

My code belike

  Future<void> example() async {
    //create point annotation-managers
    final pointAnnotationOne =
        await mapboxMap.annotations.createPointAnnotationManager();
    final pointAnnotationTwo =
        await mapboxMap.annotations.createPointAnnotationManager();
    // add points
    final myPointOne =
        await pointAnnotationOne.create(mapbox.PointAnnotationOptions());
    print(myPointOne.id); //print "0"
    final myPointTwo =
        await pointAnnotationTwo.create(mapbox.PointAnnotationOptions());
    print(myPointTwo.id); //print "0"

    // remove point
    pointAnnotationOne.delete(myPointOne); // OK
    pointAnnotationTwo.delete(myPointTwo); //! throw Annotation has not been added on the map
  }

when I navigate to PointAnnotationController.kt, I see that different annotation managers are using the same annotationMap instance 🤔

class PointAnnotationController(private val delegate: ControllerDelegate) :
  FLTPointAnnotationMessager._PointAnnotationMessager {
  private val annotationMap = mutableMapOf<String, PointAnnotation>()
  private val managerCreateAnnotationMap = mutableMapOf<String, MutableList<String>>()

  override fun create(
    managerId: String,
    annotationOption: FLTPointAnnotationMessager.PointAnnotationOptions,
    result: FLTPointAnnotationMessager.Result<FLTPointAnnotationMessager.PointAnnotation>
  ) {
    try {
      val manager = delegate.getManager(managerId) as PointAnnotationManager
      val annotation = manager.create(annotationOption.toPointAnnotationOptions())
      annotationMap[annotation.id.toString()] = annotation // **<- is something wrong here?**
      if (managerCreateAnnotationMap[managerId].isNullOrEmpty()) {
        managerCreateAnnotationMap[managerId] = mutableListOf(annotation.id.toString())
      } else {
        managerCreateAnnotationMap[managerId]!!.add(annotation.id.toString())
      }
      result.success(annotation.toFLTPointAnnotation())
    } catch (e: Exception) {
      result.error(e)
    }
  }
  
    override fun delete(
    managerId: String,
    annotation: FLTPointAnnotationMessager.PointAnnotation,
    result: FLTPointAnnotationMessager.Result<Void>
  ) {
    try {
      val manager = delegate.getManager(managerId) as PointAnnotationManager

      if (!annotationMap.containsKey(annotation.id)) {  // **<- is something wrong here?**
        result.error(Throwable("Annotation has not been added on the map: $annotation."))
        return
      }

      manager.delete(
        annotationMap[annotation.id]!!
      )
      annotationMap.remove(annotation.id) 
      managerCreateAnnotationMap[managerId]?.remove(annotation.id)
      result.success(null)
    } catch (e: Exception) {
      result.error(e)
    }
  }

Hi @ankiimation, we have addressed the issue with duplicating annotation manager id in this pr https://github.com/mapbox/mapbox-maps-flutter/pull/366, this has been included in our v1.0.0-beta.2 release, could you please try and let us know if this issue has been fixed?
