React Native business logic

In the broadest possible sense, the state of an app is everything that exists in memory when the app is running . This includes the app’s assets, all the variables that the Flutter framework keeps about the UI, animation state, textures, fonts, and so on.

Business logic is the custom rules or algorithms that handle the exchange of information between a database and user interface . Business logic is essentially the part of a computer program that contains the information (in the form of business rules) that defines or constrains how a business operates.

The state management is one of the most popular and necessary processes in the lifecycle of an application . According to official documentation, Flutter is declarative. It means Flutter builds its UI by reflecting the current state of your app.
