In this blog post, we'll explore efficient state management in Flutter applications using ValueNotifier and EfficientBuilder within the MVVM (Model-View-ViewModel) architectural pattern. The MVVM architecture consists of three key components: Model: Represents the data and business logic View: Handles the UI presentation ViewModel: Manages state and business logic between Model and View In our approach, we’ll be refining the ViewModel by separating its states into a dedicated State class. This ensures that the ViewModel focuses solely on managing logic while the State class handles state representation. Traditionally, in MVVM, the ViewModel is responsible for both state management and business logic. However, by decoupling these concerns, we create a more structured and maintainable architecture. No more talking. Lets, implement it together. 1. Efficient Builder: We are going to use Efficient Builder package for this. So, go to pub.dev. Add the package to you pubspec.yaml file...
