# 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>;
