jolt

Use when building Flutter widgets in a setup-once / hooks-driven composition style — declaring signals, controllers, listenables, effects, timers, and lifecycle callbacks through `use*` hooks inside a `setup` function that runs once, owns and disposes those resources, and returns a builder for reactive rebuilds. Provides SetupWidget, SetupMixin (on existing StatefulWidget), and SetupBuilder.

Use when Flutter widgets need to track Jolt signals and rebuild automatically when those signals change — typically with JoltBuilder — or when converting between Flutter Listenable / ValueNotifier and Jolt signals.

Use when modeling reactive state in Dart with Jolt — owning mutable state with signals, deriving values from other reactive reads, reacting to changes with effects or watchers, or bridging reactive state with Future / Stream / async loading.
