babelHelpers.asyncGenerator.wrap not defined

[arv]

Description

When adding transform-async-generator-functions to .babelrc I'm getting an error:

undefined is not an object  (evaluating 'babelHelpers.asyncGenerator.wrap')

Reproduction

.babelrc:

{
  "presets": ["react-native"],
  "plugins": [
    "transform-async-generator-functions"
  ]
}

Js code:

async function* f() {}

According to #4844 this seems to be because RN changes how babelHelpers works?

Additional Information

• React Native version: 0.36
• Platform: both
• Operating System: macOS

The problem is still present.

• RN version 0.39.2
• transform-async-generator-functions version 6.17.0

@ErikCupal Still having issues?

[santiagofm]

Could you solve this issue @arv @ErikCupal @christopherdro ?

[arv]

I didn't. We ended up not using async generators after all.

@santiagofm you can try the solution on #14933

In my case, using react-native 0.46.x, it was enough to just downgrade babel-preset-react-native to 2.0.0 and run react-native start --reset-cache
