# asUtf8Sink method Null safety

ByteConversionSink asUtf8Sink (

1. bool allowMalformed

)
override

Returns `this` as a sink that accepts UTF-8 input.

If used, this method must be the first and only call to `this`. It invalidates `this`. All further operations must be performed on the result.

## Implementation

    ByteConversionSink asUtf8Sink(bool allowMalformed) {
      return _Utf8ConversionSink(this, allowMalformed);
    }
