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);
}
How it fits a Flutter product
| Layer | Choice |
|---|---|
| Latency-sensitive UI polish | Client Genkit / Firebase AI Logic |
| Tools, RAG, billing, audit | Server Genkit |
| Shared contracts | Dart models generated once |
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.
