All are production-ready out of the box. Q: Is this only for AI apps? A: No. AI features are an optional module. Disable them and the kit works for utility apps, productivity apps, wellness apps, subscription apps, content apps — any app category on any platform. Q: How does the theming system work? A: The kit uses Material 3 with a centralized design token system. Edit one theme configuration file and the entire app updates — brand colors, typography, spacing, corner radius, and elevation. Dynamic color support adapts to the user's wallpaper on Android 12+. Every screen reads from this single source of truth. Q: What's the setup process? A: Clone the repo, configure your Firebase project using the FlutterFire CLI, set your API keys and feature preferences, then build and run. Working app on iOS, Android, and Web in under 10 minutes.

Feature modules are self-contained, repositories use abstract interfaces, and the project structure follows a clean separation of concerns. Q: How do push notifications work? A: The kit includes both local notification support and FCM (Firebase Cloud Messaging) integration. A built-in push diagnostics screen helps troubleshoot delivery issues, manage tokens, and test notification flows. Q: How does the OpenAI integration work? A: OpenAI features are accessed through a Flask proxy backend, so API keys are never exposed in client code.
