Intro

What this library is

This is an implementation of the Model-View-ViewModel (MVVM) pattern for Flutter applications.

The current implementation follows the rules of the MVVM architecture pattern, is inspired by the internal implementation of Flutter, and incorporates positive aspects from the Business Logic Component architecture pattern and Clean Architecture principles.

Benefits of using

• Clear Layer Separation: The code is divided into layers with distinct responsibilities, making it easy even for newbie developers to get started with the library.

• High Independence Between Layers: This decoupling simplifies testing and maintenance. It also allows team members to work independently on different layers while developing a single feature, which leads to decreasing time-to-feature.

• Ease of Testing: The easier it is to test, the more cases are covered. This approach supports various test types, such as unit, widget, golden, and end-to-end tests. Writing tests with Elementary requires minimal additional effort, providing strong motivation to do it.

• Fully Declarative Widget Layer: The widget layer remains purely declarative, devoid of any logic. This aligns with Flutter's focus on declarative UI, with other layers handling the logic.

• Efficient rebuilds: Flutter’s optimized rebuild strategies are crucial for performance. Elementary uses the observer pattern for properties, minimizing unnecessary rebuilds and enhancing application efficiency.
