Overview
Scoped Model is a lightweight state management solution for Flutter that enables reactive model sharing across a widget tree. It provides a simple way to pass a model object down the widget hierarchy, allowing children widgets to reactively access and update the model. The package uses a scoped approach, ensuring that only relevant widgets rebuild when the model changes, improving performance. It's ideal for small to medium-sized apps where a full-fledged state management solution like Provider or Bloc might be overkill. With support for all major platforms, it integrates seamlessly into existing Flutter projects.
