Hi @rohithmada00, apologies for the late reply. I had already completed this a few days ago, it was a pretty big change as the dependencies we were using are no longer supported. So I decided to rewrite the entire application from scratch and also organise the code in a better way. I will be creating more issues soon, so feel free to star this repo and keep an eye on the issues tab.
