В Flutter Как выбрать в качестве списка файлов (List <File>), используя multi_image_picker?

Question

Я использую библиотеку multi_image_picker , чтобы выбрать Assets из галереи. Это работает нормально. Как я могу выбрать изображения как File, используя ту же библиотеку?

это мой код, я получил его из документации multi_image_picker,

import 'package:exa/Controller/DatabaseHelper.dart';
import 'package:flutter/material.dart';
import 'package:multi_image_picker/multi_image_picker.dart';
import 'dart:async';


class UpdateStatus extends StatefulWidget {
  @override
  _UpdateStatusState createState() => _UpdateStatusState();
}

class _UpdateStatusState extends State<UpdateStatus> {

  DatabaseHelper databaseHelper=new DatabaseHelper();

  List<Asset> images = List<Asset>();
  String error = 'Error Dectected';



  @override
  void initState() {
    super.initState();

  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Create Post'),
        actions: <Widget>[
          Padding(
            padding: const EdgeInsets.all(18.0),
            child: InkWell(
              child: Text(
                'POST',
                style: TextStyle(fontSize: 18.0),
              ),
              onTap: () async {

                  print('work');
                /*
                for (int i = 0; i < images.length; i++) {
                  var path = await FlutterAbsolutePath.getAbsolutePath(images[i].identifier);
                  print(path);
                }
                */
                  databaseHelper.uploadpostsimages(images);


              },
            ),
          )
