Expo listener for new files

You want to listen for new files in an Expo project. There are a few ways to achieve this, depending on your specific requirements. Here are a few approaches:

Use the FileSystem API: Expo provides a FileSystem API that allows you to access the file system and listen for changes. You can use the watch method to watch for new files in a specific directory.
```
import { FileSystem } from 'expo';
```

const directory = FileSystem.documentDirectory + 'myFiles';

FileSystem.watch(directory, (event) => { if (event.type === 'created') { console.log('New file created:', event.path); } });

2. **Use a library like `react-native-fs`**: `react-native-fs` is a popular library that provides a more comprehensive file system API for React Native. You can use it to watch for new files in a specific directory.
```javascript
import RNFS from 'react-native-fs';

const directory = RNFS.DocumentDirectoryPath + 'myFiles';

RNFS.watchFile(directory, (event) => {
  if (event.type === 'created') {
    console.log('New file created:', event.path);
  }
});

Use a third-party library like expo-file-system-watcher: This library provides a simple way to watch for new files in an Expo project. You can install it using npm or yarn.
```
import { FilesystemWatcher } from 'expo-file-system-watcher';
```

const watcher = new FilesystemWatcher(); watcher.watch(directory, (event) => { if (event.type === 'created') { console.log('New file created:', event.path); } });


4. **Use a cloud-based solution like AWS Lambda or Google Cloud Functions**: If you're building a serverless application, you can use a cloud-based solution to listen for new files and trigger a function when a new file is created.

Remember to check the documentation for each library or API to learn more about the specific requirements and limitations.
