 Questions asked (with my answers):
 
 **Q**: Why did you decide to use the apps (framework and tools I assume) you used?\
-**A**: I decided to use Flutter primarily because of its cross-platform capabilities and its integration with the [Material design specification](https://m3.material.io/). I also decided to use it because I had some previous experience with Flutter and Dart, and Dart is somewhat similar to Java which I also had experience with.
