Script to create a File Picker / File explorer React Native

This article helps programmer code for the File picker or File explorer in the React Native. UI can be customised as per the need or the type of application.
Lets start, to open the file explorer in a React Native app, you can use the FileSystem module from the react-native-fs library.
Here’s an example of how you can use it to open the file explorer and select a file:

import { FileSystem } from 'react-native-fs';

const selectFile = async () => {
  try {
    const file = await FileSystem.openPickerAsync({
      type: '*/*', // allow any type of file to be selected or add your choice like .txt, .jpg
    });
    console.log(file); // the selected file object. The 'file' object can also be returned to the calling program for further use. 
  } catch (error) {
    console.error(error); //handle error or send the better user readable response.
  }
};

This will open the file picker and allow the user to select a file. When the user selects a file, the file object will contain information about the selected file, including the file’s name and path.

Keep in mind that the react-native-fs library only works in a React Native environment, and may not be available in other types of applications.
