The previous post was about Design process. In this article we will discuss the Development process . Google Flutter Flutter is Google’s UI toolkit for building beautiful, natively compiled applications for  mobile ,  web , and  desktop  from a single codebase.  We can use the flutter for the Front-end design and Back-end design. The language that is used is DART.                  For learning dart language :  https://dart.dev/ Firebase Firebase is use mainly for back-end develop. If we want to real time database or Cloud firestore facility I said this is the most suitable platform. It's free for use. Learn About Firebase :  https://firebase.google.com/ Then we have to move to the next process level. The important fact is the we can use SQLite instead of Firebase. I preferred firebase is more efficient and easy to implement database among others. Thank You
