Description
This adds the Verdure example app to the examples directory. It includes both a Flutter client and a Python server that acts as a landscape client intake app which uses GenUI to render the intake forms that are appropriate for the given uploaded photo.
Summary of Changes
This pull request delivers a significant new example application, Verdure, demonstrating a full-stack AI-powered landscape design workflow. It integrates a Flutter client with a Python A2A server, showcasing dynamic UI generation via GenUI. The example covers user interaction from photo upload and questionnaire completion to design presentation and order confirmation. Alongside this new feature, several critical issues in core UI and validation libraries were identified and addressed, ensuring the stability and correctness of the underlying frameworks.
Highlights

It processes user queries, including image uploads, and generates A2UI JSON responses to drive the Flutter client's UI. It also includes a tool to fetch landscape options and handles session management.breakstatements in switch cases withinpackages/flutter_genuiandpackages/json_schema_builderwere addressed. These omissions caused unintended fall-through logic, leading to incorrect UI rendering and data validation behavior.packages/flutter_genui_a2uidependency was updated to usea2a: ^3.1.0. Additionally, the root.gitignorewas modified to include Python-specific ignore patterns and adjust existing Flutter/Firebase patterns, and the mainpubspec.yamlwas updated to include the new Verdure client in the workspace.Changelog
