[sairus2k]

Mapbox Implementation

Mapbox

Mapbox Version

default

React Native Version

0.75.2

Platform

iOS, Android

@rnmapbox/maps version

10.1.29

Standalone component to reproduce

Reproduction repo

import { Camera, Map } from '@rnmapbox/maps'
import React, { useRef } from 'react'

function MapComponent() {
  const cameraRef = useRef<Camera>(null)

  return (
               <Map cameraRef={cameraRef}>
                {/*...*/}
               </Map>
  )
}

Observed behavior and steps to reproduce

1. Init new react-native project npx @react-native-community/cli@latest init
2. Install @rnmapbox/maps
3. Add "noUncheckedIndexedAccess": true to tsconfig.json
4. Add Map component with cameraRef prop. Example
5. Run npx tsc --noEmit

Found 8 errors in 1 file.

Errors  Files
     8  node_modules/@rnmapbox/maps/src/components/Camera.tsx:450

Expected behavior

Changes to project local typescript configuration should not impact files imported from node_modules

Notes / preliminary analysis

Possible Solution

Update paddingConfig type declaration:

Change the type from number | number[] to number | [number, number] | [number, number, number, number]. This ensures a stricter type safety as only these specific array lengths are meaningful and expected in the context of the Camera component.

Enable noUncheckedIndexedAccess for the project:

By enabling this flag for the entire project, similar issues can be prevented in future development cycles, enforcing stricter type checks and improving overall code robustness.

@sairus2k pls include repro steps, to reproduce in a new project, to ensure it's not something in your project settings. Staring with npx @react-native-community/cli@latest init, thanks
