I recently finished from one of my side projects, it took me 2 weeks to learn flutter and build a project with it.
basically OneSpot is place where you add your social accounts into an account and when you share the link people can see the accounts you shared. It is available as web version and android app.
For this project I used Flutter for mobile application and angular for the web app, I also used Backendless, Firebase, PHP and Netlify.
I don't think that this is a successful project bu I hope more people use it soon.
