I have a school assignment for making a simple application - a currency converter. The programming language is flutter. The teacher said we are allowed to use guides for existing similar projects since we are new, and I ended up finding a tutorial for a very similar project: https://www.blunix.com/blog/building-your-first-flutter-app-a-step-by-step-guide-to-creating-a-unit-converter.html It was a unit converter, so I just changed the physical units to currencies, but my teacher said that it was a poor job, she didn't mention anything about using the tutorial so it's not that. Does anyone know what is wrong with the example shown in the tutorial?
You should have looked around before choosing that tutorial - it's woefully inadequate https://forums.digitalpoint.com/threads/a-flutter-tutorial-for-beginners.2880755/#post-19760705 Post some screenshots of your app and we can give better feedback. What was the full critique from your teacher?
