TypeError: null is not an object (evaluating 'RNDocumentPicker.pick')

[dotku]

Here is my full code, I got error with TypeError, null is not an object?!
Why?

import React from "react";
import { View } from "react-native";
import { Button, IconButton, TextInput } from "react-native-paper";
import DocumentPicker from "react-native-document-picker";

export default function PostAdd() {
  const selectFile = () => {
    DocumentPicker.pick({
      type: [DocumentPicker.types.allFiles],
    }).then((res) => {
      console.log("res : " + JSON.stringify(res));
    });
  };

  return (
    <View>
      <TextInput
        multiline
        numberOfLines={5}
        placeholder="What's on your mind?"
      />
      <IconButton icon="camera" onPress={selectFile} />
      <Button>Post</Button>
    </View>
  );
}

On iOS, running pod install in ios directory fixed this for me.
