Opaque type aliases are not converted to runtime representations.

The following input results in no output from babel.

opaque type Foo = string

---

What is the expected behaviour?

It should result in the following code (maybe with a marker for opaqueness)

const Bar = _flowRuntime2.default.type('Bar', _flowRuntime2.default.string());

---

Which package versions are you using?

"flow-runtime": "^0.17.0",
"babel-plugin-flow-runtime": "^0.17.0"

I'm having the exact same problem. As soon as I define some opaque type I'm getting flow-runtime: Cannot resolve type: MyOpaqueTypename error.

I would love to have this fixed

I have spent tons of time rewriting flow-runtime, and then lost all my work when I lost my laptop. So... a bit of a bummer that was.

I will get back to working on this sometime in a not too distant future. Meanwhile, any PRs I will make sure to close/ release quickly.

Ok thanks for update. idd that sucks If you write the test I will write the code to make the test pass :-)
