I was able to get it to work yesterday on a Mac. Scanning is so much faster using onGoogleVisionBarcodesDetected. I just added the snipped to the Podfile like you did:

pod 'react-native-camera', path: '../node_modules/react-native-camera', subspecs: [
  'BarcodeDetectorMLKit'
]

and then ran pod update.

Used versions are:

CocoaPods 1.10.1
react 17.0.2
react-native 0.64.2
react-native-camera 4.1.1
GoogleMLKit 2.3.0
MLImage 1.0.0-beta1
MLKitBarcodeScanning 1.4.0
MLKitCommon 3.1.0
MLKitVision 1.3.0
