Standalone component to reproduce
import React, { useState } from 'react';
import { LineLayer, ShapeSource, PointAnnotation } from '@rnmapbox/maps';
import { View } from 'react-native';
import { Button } from 'react-native-paper';
const EditFieldBoundary = () => {
const featureCollection = () => {
return {
type: 'FeatureCollection',
features: [
{
type: 'Feature',
id: 'a-feature',
properties: {},
geometry: {
type: 'LineString',
coordinates: [74,7354736583765,36.84765843584],
},
}
]
};
};
const [selectedCoordinates, setSelectedCoordinates] = useState();
const [draggedPoint, setDraggedPoint] = useState({ index: -1, point: null });
const draggingEditablePoint = (feature) => {
console.log(feature)

console.log(feature)

<ShapeSource id="dottedLineSource" shape={featureCollection()}>

draggable
onSelected={(feature) => {}}
onDragStart={(feature) => {
setDraggedPoint({
index,
point: [feature.geometry.coordinates[0], feature.geometry.coordinates[1]]
});
}}
onDrag={(feature) => draggingEditablePoint(feature)}
onDragEnd={(feature) => changeCoordinate(feature)}>
<View
style={{
zIndex: 100000,
width: 20,
height: 20,
borderRadius: 50,

</PointAnnotation>

Observed behavior and steps to reproduce
I have a use case where I need to show a circle shape for all the vertices for the polygon and should able to drag the vertices circle to adjust the polygon shape (Attached Image). I am using Pint Annotation along with the LineLayer for this use case but point annotation always comes underneath the line layer. I have tried solutions like setting the higher zIndex for the point annotation or rendering point annotation after line layer rendering is done but nothing seems to be working. Could someone please help here since this is a blocker for the whole feature?
Expected behavior
There should be a way where i should able move the point annotation above any other layer.

Research direction
No source files or tests are named. Start by running the provided PointAnnotation and LineLayer reproduction on iOS and Android, then trace how their rendering order is determined; done means the point annotations render above the line layer while remaining draggable.
