ReactiveStreamBuilder<T> class
A convenience widget that rebuilds itself whenever a Reactive<T> value changes.
This widget wraps a Reactive<T> in a StreamBuilder, using the reactive's
internal broadcast stream. It automatically provides the current value as
initialData, so the builder always has an initial snapshot.
Example:
final counter = Reactive<int>(0);
ReactiveStreamBuilder<int>(
reactive: counter,
builder: (context, snapshot) {
return Text('Value: ${snapshot.data}');
},
);
counter.value++;
