What's inside Flutter in Banking eBook?

LeanCode's Flutter Team, along with other partners, developed probably one of the biggest Flutter apps in the world for Credit Agricole Bank Polska. It's also the ultimate proof that Flutter is enterprise-ready and can be used to deliver a complex banking product.

In this project, a team of 200+ people participated for 11 months in a challenge to release an outstanding application, "CA24 Mobile", that will enable our client to advance in Poland's highly competitive banking market.

This ebook is packed with technical details about delivering the banking app with Flutter. We share the information that often remains hidden in such large-scale projects.

This ebook covers such aspects as:

How to organize the scope of work divided into 15 squads?
How to share code ownership?
How to structure cross-team communication?
How to conduct end-to-end automated testing?
How to run things in a multi-package environment?

But that's not all! In a mobile banking app development, everything is on a big scale - also the Design System and the number of components and challenges that come with that.

In this ebook, you will also read about:

How many components can be in such a large-scale project?
What technical and logistic issues can a developer face during design implementation?
How detailed a Story Book needs to be?
What are Design System responsibilities and what are not?
Why does it matter to consider Motion Design as soon as possible?
How does the communication look between developers and designers?

Plus, you get to read about the entire process of developing a banking app, starting from business aspects and decisions and ending with the release of the application to the market.
