global.TYPED_ARRAY_SUPPORT is undefined for react-native

See original GitHub issue

I get the above error on import AWS from 'aws-sdk/dist/aws-sdk-react-native. Others have gotten when using babel-preset-env instead of module:metro-react-native-babel-preset

"@babel/runtime": "^7.1.2",
"aws-sdk": "^2.198.0",
"buffer": "^5.2.1",
"@babel/plugin-transform-runtime": "^7.1.0",
"metro-react-native-babel-preset": "^0.48.2",
"react": "^16.6.0-alpha.8af6728",
"react-native": "^0.57.4",

I fixed it by editing node_modules/aws-sdk/dist/aws-sdk-react-native.js and changing the below code to Buffer.TYPED_ARRAY_SUPPORT = typedArraySupport().

Buffer.TYPED_ARRAY_SUPPORT = global.TYPED_ARRAY_SUPPORT !== undefined
	  ? global.TYPED_ARRAY_SUPPORT
	  : typedArraySupport()

I believe this is a problem with babel polyfilling global and is maybe related to webpack.
