import 'dart:io' show Platform;
import 'package:flutter/foundation.dart' show kIsWeb;


if (Platform.isAndroid || Platform.isIOS)) {
 // use file_picker plugin
      FilePickerResult? result = await FilePicker.platform.pickFiles();
     if(result != null) {
     File file = File(result.files.single.path);
     } else {
     // User canceled the picker
     }
} else if(kIsWeb) { 
  // use file_selector plugin 
 final typeGroup = XTypeGroup(label: 'images', extensions: ['jpg', 
  'png']);
   final file = await openFile(acceptedTypeGroups: [typeGroup]);
} else {
// use file_picker_desktop
   try {
   final result = await pickFiles(
   allowMultiple: false,
   );
    if (result != null) {
    File file = File(result.files.single.path);
    } else {
    // User canceled the picker
