The only dcr to swf conversion we know about, is potential use of Kodak Digital images (.dcr) for making new (old) Flash content, which was certainly possible in the past with one of the many Flash tools. But it is more likely that you would have to first export the .dcr file to some common raster format that can be used in Flash.
As for conversion, this seems incredibly unlikely, especially since the official support for Flash has ben dropped few years ago.
