QR Code

QR Code App

This project began as an idea to create a QR Code app, initially aimed at providing a simple tool for generating and scanning QR codes. I envisioned it as a small, straightforward mobile app that would let users generate QR codes for text and URLs, and scan them with ease. My first goal was to create something basic, using standard Flutter libraries to achieve the desired functionality.

But as I delved deeper into the development, I realized I could add more features that would enhance the user experience. Why stop at just generating QR codes? I decided to include QR code scanning as well, and explored integrating real-time scanning with the mobile_scanner package. Not only could users generate QR codes, but now they could easily scan and interact with the codes they encountered.

The project quickly grew from a simple concept to a more feature-rich app. I expanded the app to allow users to share and save QR codes, making it even more versatile. I also added some modern UI elements, using custom fonts and ensuring cross-platform support for both Android and iOS.

What started as a simple idea for a QR Code app evolved into a full-fledged mobile tool, one that I could see being used in both personal and professional settings. It became a great way for me to explore Flutter and push my development skills further, creating an app that I’m genuinely proud of.
