Flutter is an app SDK for building high-performance, high-fidelity apps for iOS, Android, and web (tech preview) from a single codebase.

The goal is to enable developers to deliver high-performance apps that feel natural on different platforms.

With an interest to learn how this Flutter technology works, we developed an app called Cash on Swipe for our client Bala.

We also integrated Google sheets into this app and we are using those sheets as our backend.
