StreamTransformer<S, T>.fromBind constructor Null safety

  1. @Since("2.1")
StreamTransformer<S, T>.fromBind(
  1. Stream<T> bind(
    1. Stream<S>
    )
)

Creates a StreamTransformer based on a bind callback.

The returned stream transformer uses the bind argument to implement the StreamTransformer.bind API and can be used when the transformation is available as a stream-to-stream function.

final splitDecoded = StreamTransformer<List<int>, String>.fromBind(
    (stream) => stream.transform(utf8.decoder).transform(LineSplitter()));

Implementation

@Since("2.1")
factory StreamTransformer.fromBind(Stream<T> Function(Stream<S>) bind) =
    _StreamBindTransformer<S, T>;
