The target of a Stream.transform call.

The Stream.transform call will pass itself to this object and then return the resulting stream.

It is good practice to write transformers that can be used multiple times.

const
factory
StreamTransformer.fromHandlers({void handleData(S data, EventSink<T> sink), void handleError(Object error, StackTrace stackTrace, EventSink<T> sink), void handleDone(EventSink<T> sink)})

Creates a StreamTransformer that delegates events to the given functions.

Methods

bind(Stream<S> stream) Stream<T>

Transform the incoming stream's events.

noSuchMethod(Invocation invocation) → dynamic

noSuchMethod is invoked when users invoke a non-existent method on an object. The name of the method and the arguments of the invocation are passed to noSuchMethod in an Invocation. If noSuchMethod returns a value, that value becomes the result of the original invocation.

toString() String
