Hi,

Can anyone recommend a good way to add a SDK constraints that says "any version of 1.6, even if it's dev" ?

I have this:

environment:

sdk: ">=1.6.0"

But I get this error:

sethladd:~/Code/simple_http_server (master)$ pub global activate simple_http_server

Downloading simple_http_server 0.1.0+2...

Resolving dependencies...

Package simple_http_server requires SDK version >=1.6.0 but the current SDK is 1.6.0-dev.4.0.

I tried added .dev at the end of my sdk constraint, but that didn't work. I checked https://www.dartlang.org/tools/pub/dependencies.html#version-constraints but I missed any reference to .dev.

Thanks for any tips!

Seth

I think having "-dev" rather than ".dev" at the end of the constraint should work. Or possibly -dev.1.0 or something similar. The minus is actually significant as a +/- thing, so 1.6.0 means the released version, and 1.6.0-something means with a version lower than 1.6.0.

Nice, thanks Alan! That did the trick:

environment:

sdk: ">=1.6.0-dev"

In general, it's a good idea to specify a particular prerelease version that you know to work. If 1.5.0 doesn't have the feature you're using, it's likely that early dev releases don't either, so you don't want to include them in your constraint.

What's new in SDK 1.6.0?

Thanks!

Good point. I should specify the exact dev version that I have.
