Widgets and utilities to deal with streams

Features

StreamedLoading

A circular indicator that will show looking to a boolean stream representing the loading status.

You can customize stroke size and color.

StreamedLoading(
  stream: _loadingController.stream,
  color: Colors.Blue,
  strokeWidth: 4.0,
);

Loading mixin

A mixin that adds a BehaviorSubject<bool> to a class. This way you can easily deal with a stream representing the loading status.

You can set the loading status using loadStart() and loadStop() functions. To retrieve the loading status you can use the isLoading getter.

StreamWidget

This is a wrapper of StreamBuilder. It allows to define:

• an onData: (data) {} callback that must return the Widget to show when the stream has data
• an onError: (error) {} callback that must return the Widget to show when the stream has errors
• an onLoad: widget to be returned when the stream has no data nor errors
