 Mandatory method that will transform code. The object received has information about the module being transformed (e.g its path, code...) and the returned object has to contain an `ast` key that is the AST representation of the transformed code. The default shipped transformer does the bare minimum amount of work by just parsing the code to AST:
 
 ```js
-const babylon = require('metro-babylon7');
+const babylon = require('babylon');
 
 module.exports.transform = (file: {filename: string, src: string}) => {
   const ast = babylon.parse(code, {sourceType: 'module'});
