android/app/src/main/AndroidManifest.xml:

<uses-permission android:name="android.permission.BLUETOOTH_SCAN" android:usesPermissionFlags="neverForLocation" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" android:maxSdkVersion="30" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" android:maxSdkVersion="30" />

If you use BLUETOOTH_SCAN to determine location, remove android:usesPermissionFlags="neverForLocation"

If you use location services in your app, remove android:maxSdkVersion="30" from the location permission tags
