Fix NullPointerException

✅ Solution

NullPointerException in Flutter, particularly with plugins like google_maps_flutter, often arises when accessing properties or methods of a variable that hasn't been properly initialized or has become null unexpectedly. To fix this, carefully inspect the stack trace to identify the null object and ensure it's properly initialized before use; implement null safety checks (using `?` operator or `if (object != null)`) to prevent accessing potentially null values. For google_maps_flutter, ensure the GoogleMapController is initialized and ready before manipulating markers or other map features.
