StreamBuilder<T> constructor

const StreamBuilder<T>({Key key, T initialData, Stream<T> stream, @required AsyncWidgetBuilder<T> builder })

The initialData is used to create the initial snapshot.

The builder must not be null.

Implementation

  this.initialData,
  Stream<T> stream,
  @required this.builder
}) : assert(builder != null),
     super(key: key, stream: stream);
