bufferFuture method
Creates an Observable where each item is a List
containing the items
from the source sequence, batched whenever onFutureHandler
completes.
Example
new Observable.periodic(const Duration(milliseconds: 100), (int i) => i)
.bufferFuture(() => new Future.delayed(const Duration(milliseconds: 220)))
.listen(print); // prints [0, 1] [2, 3] [4, 5] ...
Implementation
Observable<List<T>> bufferFuture(Future<dynamic> onFutureHandler()) =>
transform(new BufferStreamTransformer<T>(onFuture(onFutureHandler)));
