WARNING: dart:mirrors support in dart2js is experimental, * and not recommended.

When convert to JS I having this warning for my project using package:redstone_mapper:

• WARNING: dart:mirrors support in dart2js is experimental,
• and not recommended.
• This implementation of mirrors is incomplete,
• and often greatly increases the size of the generated
• JavaScript code.

My question, is it save to use redstone_mapper in production?

[austincummings]

You can get rid of this by adding redstone_mapper to the transformers section in your pubspec.yaml file.

[SatWiz]

I saw that in the older docs. But it looks like it is not working in version 0.2.0-beta.1 which I used now. As I still get the warning with the redstone_mapper in the yaml_file.

[SatWiz]

Are you still working on the 0.2.0 transformer and is it better to use previous version of the redstone_mapper for more stability?

[austincummings]

@SatWiz I would recommend using the previous version. This project is currently going through a ownership transition and we still need to learn the code.

@SatWiz It seems like the transformer isn't working correctly. I personally stopped using redstone_mapper in favor of dogma_codegen. However, if you are still having problems with this, I could take a look at it.

[SatWiz]

thanks Pacane, thought I had use dart bridge as replacement. So no need anymore ;)

[Pacane]

If you want some help about using dogma-codegen though. let me know. I've also written a small post about it. http://stacktrace.ca/json-serialization-in-dart-with-dogma
