Getting Started with Gemini API Integration

1. Set up your Project

Before creating a project, we assure here that you are familiar with creating projects with Dart. For this integration, you will need the latest version of Apps (Dart 3.2.0+). Before calling Gemini API, you need to set up your project. This includes setting up an API key, adding the SDK, and setting up the model.

2. Setting up API Key

To use the Gemini API, you will need an API Key. If you do not have one, you can create one in Google AI Studio.

3. Secure Your API Key

You need to keep your API Key. We highly recommend not directly using the API key in your code, or checking files that contain the key. You must use a secret store for the use of your API. We assure here that you are accessing your API key as an environment variable. For creating a flutter app, you can use String.fromEnvironment and pass —dart-define=API_KEY-$API_KEY to flutter build or flutter run for the compilation of API key as the environment variable will be different while working off the app.

4. Install SDK Package

In your application, it is mandatory to add the google_generative_ai package for using Gemini API.


$ dart pub add google_generative_ai


$ flutter pub add google_generative_ai

5. Initialization of Model

Before making any API calls, it is mandatory to import and initialize generative models.

Initialization of Model

You can implement different use cases with Gemini API

You can implement different use cases with Gemini API

  • Generate text from text-only input
  • Generate text from text and image input
  • Built multi-turn conversations
  • Use streaming for faster interactions

When above instances, we will use the gemini_pro model with the generateContent method for generating a text output.
