Build a Generative AI Travel Planner with Flutter, Firebase, and Google AI

Agentic Travel Planning App

• 💡 An AI-powered travel planning app is demonstrated, built using Flutter, Vertex AI, Gemini, and the Places API.
• 🎯 The app allows users to describe their desired vacation via text, image, or voice, with AI generating travel suggestions.
• 🗺️ Suggestions are sourced from a database pre-generated using Gemini and Imagen.

Prototyping with Firebase Studio

• 🛠️ Firebase Studio is used for easy coding and integration of Google products.
• 🎬 Two video walkthroughs showcase the app: one with a simple search interface and pre-generated results, and another with an AI-assisted multimodal search combining text and images.

Technology Stack and Integrations

• 🔗 Genkit framework provides AI capabilities, enabling agents to call tools for interacting with the environment, such as searching for nearby restaurants.
• ☁️ A fully managed PostgreSQL database powered by Cloud SQL is integrated for scalable and secure data storage.
• 📊 Firebase Data Connect offers schema and query management using GraphQL, integrating with Firebase Authentication and enabling vector similarity search with queries like get nearest places.
• 📍 The Places API is integrated via Genkit's tool calling to gather detailed location information and enhance recommendations.

Personalized Trip Generation with Gemini and RAG

• ✈️ Users can import dream trips using text, speech-to-text, or images.
• 🧠 Gemini API with Retrieval Augmented Generation (RAG) is leveraged to provide tailored trip overviews.
• 🗄️ Firebase Data Connect and embeddings are used for nearest neighbor search, and Gemini and Imagen are used for pre-generating trip suggestions and images.

Flutter App Communication and Deployment

• 📱 The Flutter application communicates with Firebase Genkit, defining schemas for validating LLM outputs and ensuring reliable data consumption.
• 📝 Zod is used for defining input and output schemas for validation, and dotPrompt is a Genkit plug-in for crafting effective prompts.
• 🚀 The Flutter application is deployed to Firebase Hosting, which integrates seamlessly with modern web frameworks for secure and managed server environments.
