orchestra
v1.0.2
Reactive state management for Dart and Flutter. Strict separation of data, behaviour, and events, with a built-in DevTools Inspector for live entity inspection and system timing.
Open Source
Open-source Flutter, Dart & .NET packages.
We publish and maintain 20 open-source packages across pub.dev and NuGet, built for the same production systems we deliver for clients. On the Flutter side: Orchestra, a reactive state management library, and keycloak_client for Keycloak login. On the backend: the Winche Stack, a self-hosted, Firestore-style backend for .NET built on PostgreSQL.
Flutter & Dart packages
Published on pub.dev under the verified publisher winchetechnologies.co.uk: the Orchestra state management family, Keycloak authentication for Flutter, and the client SDKs for the Winche Stack.

Type-safe Dart client for Winche Database: an offline-first, real-time document store with queries, listeners, batches, and transactions over a single WebSocket.

.NET packages
Published on NuGet: the Winche Stack, a self-hosted, Firestore-style backend for .NET built on PostgreSQL (database, file storage, rules engine, and admin console), plus authorization and Keycloak libraries for ASP.NET Core.
Winche Stack
Winche.Database
v10.0.0
A JSON document database layer for .NET built on PostgreSQL JSONB. Store, query, and subscribe to documents, with Firestore-style access rules, REST and WebSocket endpoints, secondary indexes, and TTL policies.
