Enhance Error Handling: Implement more robust error handling when fetching weather data from the OpenWeather API. Currently, the app may not handle scenarios where the API is unreachable or returns an error (e.g., invalid city name). Adding specific error messages will improve user experience and help users understand what went wrong.
