The objective of this project was to be introduced to Asynchronous programming in Dart, and how to implement that to fetch Weather Data from an API Source based on the user's current location. It also provides the users with an option to enter a specific city name and fetch weather data for that particular city. Failing to get Weather is also handled through exception handling and the users are greeted with an error message.
I have made a weather app inspired by the beautiful designs made by Olia Gozha. Using this app, a user would be able to find out the live weather data in the current location of the device as well as the weather for any city you can think of!
