An implementation of Stability AI SDK in Dart. Stability AI is a solution studio dedicated to innovating ideas.


  • Stability AI requires you to create your own API key to make calls to the API. You can create one here.

  • Create a .env file and set your Stability AI API key


The example provided is using the SDK directly in a Flutter app. In most cases, you’re going to use the SDK in the backend using tools like Dart Frog. This is to secure the API key and to have more control of the incoming requests, e.g. controlling rate limits or blocking sensitive content.

// 1. Setup the API client
final client = StabilityApiClient.init("<YOUR_API_KEY_HERE>");

// 2. Create a generation request
final request = RequestBuilder("an oil painting of a dog in the canvas, wearing knight armor, realistic painting by Leonardo da Vinci")

// 3. Subscribe to the response
client.generate(request).listen((answer) {
    image = answer.artifacts?.first.getImage();
