Can't used it with DDC

Is it ready to work with DDC or not yet? I have this error when I test it in Chrome browser.

Please fix all errors before compiling (warnings are okay).

this is caused because stream_transformers library is not strong mode aware, until that library get updated we cannot do to much.

A possible solution could be to remove the dependency to that library

[mohammed90]

I think it is possible to swap out stream_transformers with rxdart with no trouble. Both of their transformers implement StreamTransformer<T, T> and rxdart is strong mode aware.

I'll check it tomorrow, thanks for the tip

[Francessco121]

There is also the stream_transform package maintained by the Dart team. It uses strong-mode and appears to support the same operations.

Thanks I'll test it.
