Summary of Changes

Hello, 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 introduces Google Maps grounding capabilities to the AI React application. This feature allows the AI model to incorporate geographical context into its responses, enhancing the relevance and accuracy of location-based queries. The changes include UI updates for activating and configuring Google Maps grounding, as well as necessary backend service and dependency updates to support this new functionality.

Highlights

• Google Maps Grounding Integration: Introduced a new feature to enable grounding AI responses with Google Maps, allowing the model to leverage geographical information for more relevant and accurate location-based queries.
• Enhanced UI Controls: Added dedicated UI toggles and input fields in the Right Sidebar for activating Google Maps grounding, enabling a widget, and specifying optional latitude/longitude context, alongside updated disabling logic for conflicting tools.
• Dynamic Input Disabling: Implemented logic to dynamically disable the prompt input and run button when an invalid or incomplete latitude/longitude pair is provided for Google Maps grounding, ensuring valid input before execution.
• Firebase Dependency Updates: Upgraded the firebase package to version 12.6.0 and several related @firebase packages, ensuring the application uses the latest SDK features, performance improvements, and security fixes.
• Refactored Source Display: Modified the chat message component to gracefully handle and display different types of grounding sources, including new Google Maps sources, with appropriate titles and URIs in both tooltips and the sources list.

Code Review

This pull request introduces Google Maps grounding functionality to the AI React application, including updating Firebase dependencies, adding UI controls in the RightSidebar for enabling/disabling Google Maps grounding, toggling a Maps widget, and inputting latitude/longitude for location context. The PromptInput component now accepts a disabled prop, which is used in ChatView to disable input when latitude/longitude are inconsistently provided. The ChatMessage component was updated to correctly display Google Maps sources in the chat history. Review feedback highlights the need to remove a console.error and debugging console.log statements, ensure the googleMaps tool update is non-destructive, and refactor the duplicated isLatLngInvalid logic into a shared utility for improved maintainability.
