dart:async

toList method

Future<List<T>> toList ()

Collects all elements of this stream in a List.

Creates a List<T> and adds all elements of this stream to the list in the order they arrive. When this stream ends, the returned future is completed with that list.

If this stream emits an error, the returned future is completed with that error, and processing stops.

Implementation

Future<List<T>> toList() {
  List<T> result = <T>[];
  _Future<List<T>> future = new _Future<List<T>>();
  this.listen(
      (T data) {
        result.add(data);
      },
      onError: future._completeError,
      onDone: () {
        future._complete(result);
      },
      cancelOnError: true);
  return future;
}
