gskinnerTeam/flutter_vignettes

This system is a collection of Flutter-based vignettes and shared UI components designed to demonstrate various user interface patterns and interactions. It provides concrete examples of modern Flutter development practices, including the Flutter V2 Android embedding, null safety, and platform-specific configurations for Android, iOS, and Windows. The codebase showcases diverse interaction models such as scroll physics, form state management, 3D rendering, and visual effects, all refactored to use current best practices and dependencies.

The plant\_forms vignette now supports Windows, adding the necessary CMake build files, C++ runner code, and resource scripts to build and run the application on that platform. Additionally, the Android configuration has been updated to use the V2 Flutter embedding, which includes updating the AndroidManifest.xml to remove the deprecated FlutterApplication class and register the Flutter engine, as well as updating the MainActivity to use the new embedding API. The project has also been migrated to support non-nullable types (nnbd) and updated to use Gradle 7.6.3.

The plant form implementation has been refactored to use dedicated page components (PlantFormInformation, PlantFormPayment, PlantFormSummary) organized under the form\_pages directory. This change introduces a Provider-based state management pattern where form data is stored in a shared state object rather than passing form values as widget parameters. The summary page now includes a 'Next' button to navigate to the information page, and the payment page uses a shared form state for validation and data storage.
