factory_core

The standalone Dart resolution engine for Factory. No Flutter dependency.

Declare Factory<T> values, group them in FactoryModule, then resolve with FactoryContainer.read. Construction is synchronous and lazy by default; close() awaits cleanup. Values supplied through overrideWithValue are borrowed.

Pass FactoryRef.resolver to a constructed instance when it needs to resolve dependencies from later methods. FactoryResolver.resolve(factory) preserves scoped/unique lifetimes and cleanup order without subscribing to changes or caching results. It stays bound to the original instance through replacements, and throws StateError after scope closure or for dependency cycles.

See the repository README for scopes, overrides, explicit observation and cleanup contracts. Flutter applications usually import the factory_provider adapter instead.
