Describe and reproduce the Bug

🐛 Bug Report

Steps to Reproduce

1.- Install MapLibre React Native in an Expo app:

npx expo install @maplibre/maplibre-react-native

2.- Add the plugin to the plugins array in app.config.js.

3.- Modify the iOS Podfile, adding the following to the post_install block:

$MLRN.post_install(installer)

4.- Rebuild the app:

npx expo run:ios

5.- Add a basic MarkerView to the map, using the MarkerView component to render a marker.

6.- Observe the error on app launch.

Expected Behavior

The MarkerView component should render correctly on the map without throwing any runtime errors.

Actual Behavior

The app crashes with the following error when rendering the MarkerView component:

TypeError: _helpers.point is not a function (it is undefined)

Upon inspecting the MarkerView.js file inside node_modules, I found that it imports point from @turf/helpers like this:

var _helpers = require("@turf/helpers");

However, logging _helpers returns the number 46 instead of the expected object containing functions like point. This suggests the module is being imported incorrectly or something is interfering with the resolution of @turf/helpers.

Reproducible Demo

A minimal project that reproduces this issue can be provided upon request.
