import 'dart:io';

void moveFile() async {
  String originalPath = '/Users/dhavalkansara/Library/Containers/com.myapp.apps/Data/Library/Caches/encryption-decryption/dummy copy 8.pdf.txt';
  String newPath = '/Users/dhavalkansara/Documents/dummy copy 8.pdf';

  try {

    File file = File(originalPath);

    // Copy the file first, then delete the original.

    await file.copy(newPath);
    await file.delete();

    print('File moved successfully');
    } catch (e) {
    print('Error: $e');
    }
}
