SignalBuilder
A signals widget builder.
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.
// sample counter
final counter = Signal(0);
@override
Widget build(BuildContext context) {
return SignalBuilder(
builder: (context, child) {
return Text('${counter.value}');
},
);
}
