crash when using fetch for html/js file

[howmind]

Hi, firstly thank your amazing working for flutter.
I have one question about fetch function.
When I fetch the html/js file, the flutter_js meets crash problem.
I have checked codes, It seems only support json file(The xhr.dart force to encode the response Text).
Could we support the fetch function to download normal file?
