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);
