Notes on Adding Generative AI Features to Flutter Apps

Introduction

• Overview of using Firebase Vertex AI in Flutter applications
• Use cases: guiding user interactions, summarizing information, content creation

Getting Started

1. Firebase Project Setup

   • Ensure Firebase project is configured with the correct APIs
   • Connect the project to your Flutter app

2. Adding Packages

   • Add Firebase Core and Firebase Vertex AI packages

3. Initialization

   • Initialize the Firebase app
   • Initialize the generative model
   • Provide the name of the Gemini model to use
   • Optionally provide a generation configuration to adjust responses
     • Parameters to set:
       • Response MIME type
       • Temperature (affects randomness and creativity)

Prompt Construction

• Construct a prompt for Gemini specifying the desired output
  • Examples:
    • "Write a story about a magic backpack"
    • "Tell me what’s in this image"
• Prompt can include various data types:
  • Text, images, video, audio, PDFs
• Use Firebase Storage for large files and include URLs in requests

Content Generation

• Use generate content method to get responses
  • Waits for full output before response
  • Alternatively, use generate content stream for real-time output

Security

• Enable Firebase App Check to verify API calls from your app
• Prevent abuse by unauthorized clients
