I am trying to make a resuable fuction with the react-native imagepicker library but when i import the function i get undefined from the component i imported it to. With a console. If you have a look at the signature of the showImagePicker function from the docs, you'll see it has no return value:. The reason you are still seeing results from the console log is that when you invoke the showImagePicker function it is calling your callback function asynchronously.
