StreamBuilder<T> class
Similar to Flutters StreamBuilder but without AsyncSnapshot. Constantly rebuild something depending of the last value of a stream. Optional you can set an errorBuilder to handle errors.
Example:
StreamBuilder<String>(
stream: someDataStream,
builder: (AsyncSnapshot<String> snapshot, Widget parent) =>
divElement(text: snapshot.data ?? snapshot.error?.toString() ?? 'No data yet'),
).appendTo(this);
