NitroInstanceRegistry class

Dart-side registry mapping native instance IDs to live impl objects.

Every generated _XxxImpl registers itself on construction and auto-unregisters when GC'd (via Finalizer) or when dispose() is called.

This enables zero-native-call downcasting:

AnyNativeObject ref = plugin.getRef();
final foo = NitroInstanceRegistry.resolve<Foo>(ref); // typed, no C round-trip

Only resolves instances created in the same Dart isolate — Dart isolates have separate heaps and independent registries.

Static Methods

register(int id, Object instance) → void
Registers instance under id. Called by every generated _XxxImpl constructor.
resolve<T extends Object>(AnyNativeObject ref) → T?
Returns the registered instance for ref cast to T, or null if not found, already disposed, or GC'd before this call.
unregister(int id, Object instance) → void
Removes instance from the registry. Called from dispose().
