requestPermissionsAsync is not a function

[brandner]

Please provide the following:

1. SDK Version: 37.0.0 - expo --version shows 3.20.1 - npm --version shows 6.14.2
2. Platforms(Android/iOS/web/all): web

Just like this post by @maxit7 at BarCodeScanner.requestPermissionsAsync is not a function, I can’t get past the requestPermissionsAsync() part of my code. I have tried his code sample, and the original sample from the docs: https://docs.expo.io/versions/v37.0.0/sdk/bar-code-scanner/#usage

I have run expo update and npm update.

I get an error:

Unhandled Rejection (TypeError): _ExpoBarCodeScannerModule__WEBPACK_IMPORTED_MODULE_15__.default.requestPermissionsAsync is not a function
