A flutter implementation of React hooks. It adds a new kind of widget with enhanced code reuse.

0.18.2+1

Improved the documentation (thanks to @Renni771)

0.18.2

• Added a reverseDuration parameter to useAnimationController

0.17.0

• useFuture/useStream's AsynsSnapshot now correctly expose the StackTrace when there is an error.
• added useRef and useCallback, similar to the React equivalents.
• initialData of useStream and useFuture is now optional.

0.16.0

Stable null-safety release

0.16.0-nullsafety.0

Migrated flutter_hooks to null-safety (special thanks to @DevNico for the help!)

0.15.0

• Added usePageController to create a PageController

0.14.1

• Increased the minimum version of the Flutter SDK required to match changes on useFocusNode

  The minimum required is now 1.20.0 (the stable channel is at 1.20.4)

0.14.0

• added all FocusNode parameters to useFocusNode
• Fixed a bug where on hot-reload, a HookWidget could potentailly not rebuild
• Allow hooks to integrate with the devtool using the Diagnosticable API, and implement it for all built-in hooks.

0.13.1

• useIsMounted now returns a function instead of a callable class.

0.13.0

• Added useIsMounted to determine whether a widget was destroyed or not (thanks to @davidmartos96)

0.12.0

• Added useScrollController to create a ScrollController
• added useTabController to create a TabController (thanks to @Albert221)

0.11.0

Breaking change:

• Removed HookState.didBuild.
  If you still need it, use addPostFrameCallback or Future.microtask.

Non-breaking changes:

• Fix a bug where the order in which hooks are disposed is incorrect.

• It is now allowed to rebuild a HookWidget with more/less hooks than previously. Example:

  Widget build(context) {
    useSomething();
    if (condition) {
      return Container();
    }
    useSomething()
    return Container();
  }
  

• Deprecated Hook.use in favor of a new short-hand use. Before:

  Hook.use(MyHook());
  

  After:

  use(MyHook());
  

0.10.0

Breaking change:

• The order in which hooks are disposed has been reversed.

  Consider:

  useSomething();
  useSomethingElse();
  

  Before, the useSomething was disposed before useSomethingElse. Now, useSomethingElse is disposed before the useSomething.

  The reason for this change is for cases like:

  // Creates an AnimationController
  final animationController = useAnimationController();
  // Immediatly listen to the AnimationController
  useListenable(animationController);
  

  Before, when the widget was disposed, this caused an exception as useListenable unsubscribed to the AnimationController after its dispose method was called.

Non-breaking changes:

• Added a way for hooks to potentially abort a widget rebuild.
• Added StatefulHookWidget, a StatefulWidget that can use hooks inside its build method.

0.9.0

• Added a deactivate life-cycle to HookState

0.8.0+1

0.3.0:

• NEW: usePrevious, a hook that returns the previous argument is received.
• NEW: it is now impossible to call inheritFromWidgetOfExactType inside initHook of hooks. This forces authors to handle value updates.
• FIX: use List
