The fal.ai Dart/Flutter client

fal_client pub.dev package Build License

About the Project

The fal_client is a robust and user-friendly library designed for seamless integration of fal model inference and training endpoints in Dart and Flutter projects. Developed in pure Dart, it provides developers with simple APIs to interact with AI models and works across all supported Flutter platforms.

Getting Started

The fal_client library serves as a client for fal APIs. For guidance on running out inference and training APIs, refer to the quickstart guide.

Client Library

This client library is crafted as a lightweight layer atop platform standards like http and cross_file. This ensures a hassle-free integration into your existing codebase. Moreover, it addresses platform disparities, guaranteeing flawless operation across various Flutter runtimes.

Note: Ensure you've reviewed the fal getting started guide to acquire your credentials and register your functions.

  1. Start by adding fal_client as a dependency:
flutter pub add fal_client
  1. Setup the client instance:
import 'package:fal_client/fal_client.dart';

final fal = FalClient.withCredentials('FAL_KEY');
  1. Now use fal.subscribe to dispatch requests to the model API:
final output = await fal.subscribe('fal-ai/flux/dev',
  input: {
    'prompt': 'a cute shih-tzu puppy'
  },
  onQueueUpdate: (update) => {print(update)}
);
print(output.data);
print(output.requestId);

Notes:

  • Replace fal-ai/flux/dev with the model of your preference. Check fal.ai/models for all available models.
  • The result type is a FalOutput.data and the entries depend on the API output schema.
