[@nativescript/google-maps] CameraUpdate.fromCameraPosition causes NullPointerException: CameraPosition must not be null

On Android, using GoogleMaps.CameraUpdate.fromCameraPosition() to update the map's camera, especially when including bearing, results in a java.lang.NullPointerException from the native Google Maps SDK.

Steps to Reproduce

• Set up a blank nativescript-vue project

• Initialize a nativescript/google-maps MapView.

• Attempt to create a CameraUpdate using GoogleMaps.CameraUpdate.fromCameraPosition() with a valid CameraPosition object.

import * as GoogleMaps from '@nativescript/google-maps';

// Assume 'map' is an initialized GoogleMaps.GoogleMap instance
// Assume 'map.cameraPosition' has valid data.
// Assume 'newHeading' is a valid number (e.g., from device orientation).

const newCameraPosition: GoogleMaps.CameraPosition = {
    target: map.cameraPosition.target,
    zoom: map.cameraPosition.zoom,
    tilt: map.cameraPosition.tilt,
    bearing: newHeading, // Or any valid number, e.g., 20
};

console.log('Input newCameraPosition:', JSON.stringify(newCameraPosition)); // This logs a valid object

try {
    const cameraUpdate = GoogleMaps.CameraUpdate.fromCameraPosition(newCameraPosition);
    // This line below is never reached
    console.log('CameraUpdate created successfully.'); 
} catch (e: any) {
    console.error("Error creating CameraUpdate:", e);
    if (global.isAndroid && e.nativeException) {
        console.error("Native Android Exception:", e.nativeException);
    }
}

Observed Error :

Error creating CameraUpdate fromCameraPosition: Error: java.lang.NullPointerException: cameraPosition must not be null
Native Android Exception during CameraUpdate creation: java.lang.NullPointerException: cameraPosition must not be null

Context & Impact :

• The newCameraPosition JavaScript object supplied to fromCameraPosition is confirmed to be valid (no null, undefined, or NaN values).

• This specific NullPointerException indicates an issue in the plugin's native bridge when converting the JavaScript CameraPosition object for fromCameraPosition.

• As per the plugin's CameraUpdate API, fromCameraPosition is the only method that allows for setting the bearing alongside other camera parameters.

• This bug currently prevents any programmatic control over the map's bearing, which is critical for features like compass-oriented maps.

Environment

• nativescript-vue: "3.0.1"
• @nativescript/google-maps : "1.8.0"
• Platform: Android
• Device Model: emulated Pixel 4 but also on hardware

CameraUpdate.fromCameraPosition の Android 実装から始め、この issue の TypeScript 例を使って失敗を再現してください。渡された CameraPosition の native bridge での変換を追跡してください。bearing が設定されている場合も含め、NullPointerException なしで有効な CameraUpdate が作成されれば完了です。
