Hookable class abstract

Hookable The immutable class that facilitates the use of Hooks in the simplest way possible by providing a new Widget implementation.

You must implement the void hooks() and the Widget build(BuildContext) methods so as to use this Widget.

class MyCounter extends Hookable {
  late final Hook<int> count;

  MyCounter() {
    count = Hook(0, this);
  }

  Widget build(_) {
    return Scaffold(
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          crossAxisAlignment: crossAxisAlignment.center,
          children: [
            Text(count.value.toString()),
            IconButton(
              onPressed: () {
                /// The widget automatically rebuilds when value of the Hook changes.
                count.value++;
              }
              icon: Icon(Icons.add),
            ),
          ]
        ),
      ),
    );
  }
}

You may override the void dispose() method to do any cleanup before the widget gets unmounted from the widget tree.

Methods

build(BuildContext context) → Widget
Represents the part of the Widget that defines the UI. This is called by the Framework when the widget is created and whenever the widget needs updating.
createElement() → HookableElement
Creates a HookableElement for the widget and stores it in the private Variable. WARNING: This function must not be overriden.
override
debugDescribeChildren() → List<DiagnosticsNode>
Returns a list of DiagnosticsNode objects describing this node's children.
inherited
debugFillProperties(DiagnosticPropertiesBuilder properties) → void
Add additional properties associated with the node.
inherited
dispose() → void
You can override this method to do any cleanup before the widget gets destroyed.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
toDiagnosticsNode({String? name, DiagnosticsTreeStyle? style}) → DiagnosticsNode
Returns a debug representation of the object that is used by debugging tools and by DiagnosticsNode.toStringDeep.
inherited
toString({DiagnosticLevel minLevel = DiagnosticLevel.info}) → String
A string representation of this object.
inherited
toStringDeep({String prefixLineOne = '', String? prefixOtherLines, DiagnosticLevel minLevel = DiagnosticLevel.debug}) → String
Returns a string representation of this node and its descendants.
inherited
toStringShallow({String joiner = ', ', DiagnosticLevel minLevel = DiagnosticLevel.debug}) → String
Returns a one-line detailed description of the object.
inherited
