MIT App Inventor Weather App — Mit-app-inventor Code
Fetches weather data from an API and displays it using Labels and ListView components.
1. Add TextBox for city name input.
2. Add Web component -> connect to weather API.
3. Bind API response to variable 'weatherData'.
4. Add Button 'Fetch' -> call API.
5. Bind Labels/ListView to display temperature, conditions.Mit-app-inventor Language Guide
