SignalBuilder

A magic widget builder that automatically rebuilds everytime a signal used inside its builder changes.

Reacts to any number of signals calling the builder each time.

The builder argument must not be null.

The child is optional but is good practice to use if part of the widget subtree does not depend on the value of the signals.

class SampleCounter extends StatefulWidget {
  const SampleCounter({super.key});

  @override
  State<SampleCounter> createState() => _SampleCounterState();
}

class _SampleCounterState extends State<SampleCounter> {
  final counter = Signal(0);

  @override
  Widget build(BuildContext context) {
    return SignalBuilder(
      builder: (context, child) {
        return Text(counter.value.toString());
      },
    );
  }
}
