call<T> method

  1. @defineHook
Signal<T> call<T>(
  1. T value, {
  2. JoltDebugOption? debug,
})

Creates a reactive signal hook with an initial value.

The signal persists across rebuilds and is automatically disposed when the widget is unmounted.

Parameters:

  • value: The initial value for the signal
  • debug: Optional debug options

Returns: A Signal that can be read and written to

Example:

setup(context, props) {
  final count = useSignal(0);
  final name = useSignal('Alice');

  return () => Text('${name.value}: ${count.value}');
}

Implementation

@defineHook
Signal<T> call<T>(
  T value, {
  JoltDebugOption? debug,
}) {
  return useAutoDispose(() => Signal(value, debug: debug));
}
