installing 'resource' library

[Nick Reid]

Hi all,

I'm trying to install the resource library that the Dart Team have released for importing static resources.  For some reason pub can't seem to do this even though I can successfully download a copy using `pub cache add resource`.  When I run `pub install` I get 

Package resource has no versions that match >=1.1.0 <2.0.0 derived from:

- <my package name> depends on version ^1.1.0

How do I get this library into my project? My dev machine is Windows 10 and I'm using the IntelliJ plugin if that matters. Any assistance you could give would be awesome.

Thanks,

    Nick

It looks like you have a version conflict. Try running pub get with --verbosity=solver. That should provide more information about the actual conflict that's causing the download to fail.

I had a similar issue. I believe it was due to the SDK. Believe resource requires 1.14 at minimum.

Thanks for the tip!  It turned out that my SDK version needed to be updated, although pub gave no indication this was an issue. Even with verbosity on it just denied the existence of the version I specified.  Curiously, pub did tell me about older versions that didn't satisfy the constraint.  Perhaps this is a bug?

[Nick Reid]

That was it! Thank you! Now I can get back to the task at hand.

Pub's version solver's error messages are currently not great. It's a known issue, and one I intend to fix, but it'll take a serious amount of effort due to the complexity of the underlying problem so I haven't gotten around to it yet.

Nick,

FYI.

If you are to use it on the server side, it will work like a charm. But when it comes to the browsers, still has some issues to be resolved before it is fully useful there.

If your purpose of using resource is to use 'package' URI to refer to your resources and you are on browsers, then you should wait for a little bit more.
