Luca Labs Expenses

The client had an old app with the same functionality but had major problems with functionality because it had to keep track of two software: IOS and Android. Our goal was to create an app that would work with an existing API, look good, and would be easy to maintain.

Since Flutter is a rather young technology, it functions very efficiently. However, sometimes it’s challenging to find the right solutions, and occasionally we have to work with volatile versions of libraries.

During development and testing, we used several versions of the server and Firebase (production, stage, development). One of the tasks was to make the server change from the application for easier testing.
The trick: even though the Firebase library itself supports this switching, some of the libraries that Firebase uses only work in default.

We made the forks of these libraries on the Github and made PR with changes that would allow the use of default within Firebase.
