orbital_state 0.3.0

Reactive state mixin and UI helpers for Orbital lifecycle objects.

0.3.0

• listen on an already-disposed owner returns a cancelled handle instead of attaching a live subscription
• make onDispose idempotent so the notifier is disposed exactly once
• defer notifier teardown when the subject is disposed from inside one of its own listeners during a notification round

0.2.2

• guard emit, watch and listen against calls made after the owning object has been disposed, fixing a ValueNotifier "used after being disposed" crash triggered by an in-flight async operation (e.g. a fetch resolving after the page was popped)

0.2.1

• minor internal cleanup; no functional changes
• depend on orbital_core ^0.2.1 and orbital_injector ^0.2.1 (dev)

0.2.0

• initial release: StateMixin<T> reactive state mixin for OrbitalLifecycle objects, with emit, watch and listen
• automatic listener cleanup on owner disposal via addDisposer
• dispose the underlying ValueNotifier from onDispose
