How to build agentic apps with Flutter and Firebase AI Logic
Build agentic apps in Flutter using Firebase Vertex AI, enabling AI-powered features like feedback management and real-time interaction with Gemini models.
Watch on YouTube ↗Key takeaways
- 🚀Integrating agentic capabilities into Flutter apps via Firebase Vertex AI is straightforward, treating AI features as another tool in the developer's toolbox rather than a complex, separate system.01:21
- 💬Real-time, bidirectional voice and video interactions with Gemini are possible using its Live API, allowing for conversational user experiences within Flutter apps.02:35
- 💡An AI agent is an application that achieves a goal by observing the world, acting upon it using available tools (function calls), and iterating until the goal is met or a stopping condition is reached.02:55
- 🔧The Vertex SDK in Firebase provides production-ready integration for accessing Gemini models in Flutter, supporting multimodal prompting, function calling, and streaming.04:21
- 🔒The Vertex SDK's native integration with App Check protects against abuse by ensuring only legitimate users can trigger API calls.05:10
- 💻Add the Firebase Vertex AI package to your Flutter project using `flutter pub add firebase_vertexai`.05:30

The digest
This presentation explains how developers can create agentic applications—apps that observe user input, reason, and take autonomous actions—using Flutter, Firebase, and Google's Vertex AI platform. The discussion highlights integrating generative AI, specifically Google's Gemini language model and Imagen image generation, into Flutter apps with Firebase’s Vertex SDK. This guidance is essential for developers seeking to enhance user interactions with AI-driven automation, reduce manual feedback cycles, and accelerate app development across platforms using a single codebase.
High-Level Overview
Agentic apps leverage advanced AI agents that go beyond simple content generation by observing input, reasoning, and performing tasks autonomously while interacting with users. This video presents a practical example: an app that processes user feedback and dynamically changes its UI based on natural language commands. By demonstrating how to integrate Google’s Vertex AI services—including Gemini (a multimodal large language model), Imagen (an image generation model), and a live bidirectional streaming API—within a Flutter app using Firebase’s Vertex SDK, developers learn to build sophisticated, conversational, and responsive applications efficiently. The approach is production-ready, enabling scalable, secure deployment while maintaining Flutter’s hallmark of multiplatform support.
