Genkit Dart: full-stack AI apps without leaving Dart

Genkit Dart is an open-source framework for AI-powered apps with a model-agnostic API (Google, Anthropic, OpenAI, …). It runs server-side or inside Flutter clients, so one language covers prototype to production.

Core ideas

  • Genkit() + plugins for providers.
  • Type-safe structured output and tool calling.
  • Multi-turn conversations and built-in observability.
import 'package:genkit/genkit.dart';
import 'package:genkit_google_genai/genkit_google_genai.dart';

void main() async {
  final ai = Genkit(plugins: [googleAI()]);
  final response = await ai.generate(
    model: googleAI.gemini('gemini-flash-latest'),
    prompt: 'Why is Dart a great language for AI applications?',
  );
  print(response.text);
}

Pitfalls

  • Shipping a giant server prompt inside the app bundle.
  • Mixing provider SDKs ad hoc instead of plugins — you lose portability.
  • Ignoring traces until production incidents.
