Summary of Changes

Hello @peterfriese, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request significantly enhances the 'FriendlyMeals' application by introducing structured AI generation for recipes and integrating Firebase Remote Config for dynamic parameter management. It also adds a usage tracking system and a paywall, laying the groundwork for potential monetization or feature gating. These changes improve the robustness of AI responses and provide greater flexibility in managing app behavior remotely.

Highlights

• Structured Recipe Generation: The recipe generation process has been refactored to use structured output. The AI now returns a Recipe object in JSON format, ensuring consistent and easily parseable data for displaying recipe details.
• Firebase Remote Config Integration: Firebase Remote Config has been integrated to allow dynamic configuration of application parameters, such as the AI model name, generation configuration (e.g., temperature, topP), and usage limits (e.g., maximum images per day).
• Usage Tracking and Paywall: A new usage tracking service has been implemented to monitor the number of AI-generated recipes per day. Once a predefined limit is reached, a 'PaywallView' is presented, prompting the user to upgrade for unlimited generations.
• Improved Recipe Details Display: The SuggestRecipeDetailsView has been updated to beautifully display the new structured Recipe data, including title, description, cooking time, ingredients, and step-by-step instructions, replacing the previous Markdown-based display.

Code Review

This pull request introduces structured generation using JSON schema and integrates Firebase Remote Config to manage model parameters. It also adds usage tracking with a daily limit, showing a paywall when the limit is reached. The changes are well-structured, separating concerns into different services. However, the core feature of using Remote Config values in the view model is incomplete, and there are a few areas for improvement regarding robustness and code style. My review includes critical feedback on the Remote Config integration and suggestions to prevent potential crashes and improve code maintainability.
