Problem: using any pick returns null, for example cannot read property 'pick' of undefined
same problem #221 #251 those issues are closed, but in the thread there are still user who still have this issue

Steps to reproduce:

  • npx create-expo-app app1
  • npx expo install react-native-document-picker

App.js

import { Pressable, Text } from 'react-native';
import * as DocumentPicker from 'react-native-document-picker'

export default function App() {
  const f = async () => {
    console.log(DocumentPicker.pickDirectory)
    console.log(await DocumentPicker.pickDirectory())
  }
  return (
    <Pressable onPress={f()}>
      <Text>Click Me</Text>
    </Pressable>
  );
}
  • npx expo start
  • connect on the server with android

Error happens

@MacKenzieHnC can you reproduce the issue with the above repo ?

commented

Hello and thanks for reporting,
the behavior you're describing is expected. Please read the docs here: https://github.com/rnmods/react-native-document-picker#expo

Thank you 🙂

I see thanks, this only made sense after reading from the start https://docs.expo.dev/develop/development-builds/introduction/ (the url linked in this repo https://docs.expo.dev/develop/development-builds/create-a-build/?redirected kind of needs someone that already familiar with the ecosystem)
