-# currency_exchange_rate_app_flutter
+# Currency Exchange Rate application using Flutter + GetIt + Dio
 
-A new Flutter project.
+## Descriptions
+👋 Hey there!
 
-## Getting Started
+As part of my Flutter course, I developed an app for some practice. I used Bloc as state manager and GetIt for dependency injection and Dio requests. Overall, I'm pretty excited about how this project turned out and I hope you will enjoy it too! ❤️
 
-This project is a starting point for a Flutter application.
