A dynamic QR Code Generator (using Vue.js)

After coding the UI for the challenge: "What if I could dynamically generate QR Codes of my own?" This is the result of that idea.

Also, I had to change the design a little. Although the QR Code container was really great-looking, my phone didn't recognize because there wasn't enough contrast.

Any feedback is appreciated. I figure that's the best way I can improve my skills.
