What is MVVM in Flutter?

A Flutter MVVM (Model-View-ViewModel ) implementation. It uses property-based data binding to establish a connection between the ViewModel and the View, and drives the View changes through the ViewModel.

Model — View — ViewModel (MVVM) is the industry-recognized software architecture pattern that overcomes all drawbacks of MVP and MVC design patterns . MVVM suggests separating the data presentation logic(Views or UI) from the core business logic part of the application.

In Flutter, the Widget represents the View of MVVM . The business logic sits in a separate ViewModel-class. The ViewModel is totally platform-independent. It contains no dependencies to Flutter and can, therefore, be easily reused e.g. in a web project.12 Haz 2018
