In Flutter How to get image path after selecting images using Multi Image Picker?

Question

I want to get an image path from selected multiple images, I'm using this link to select multiple images but I got assets, I want paths from selected multiple images because I want to upload into the API. I added this dependency in pubspec.yaml If there any good way to do this, please tell me

multi_image_picker: ^4.6.3

This is my file upload class, This UI looks similar to Facebook.

import 'dart:typed_data';
import 'package:auto_size_text/auto_size_text.dart';
import 'package:flutter/material.dart';
import 'package:multi_image_picker/multi_image_picker.dart';

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

class _UpdateStatusState extends State<UpdateStatus> {
  List<Asset> images = List<Asset>();
  String _error = 'No Error Dectected';

  Future<ByteData> byteData;
 // List<int> imageData = byteData.buffer.asUint8List();

  @override
  void initState() {
    // TODO: implement initState
    super.initState();
  }

  @override

Padding(
            padding: const EdgeInsets.all(18.0),
            child: InkWell(
              child: Text(
                'POST',
                style: TextStyle(fontSize: 18.0),
              ),
              onTap: () async {

 List<MultipartFile> multipart = List<MultipartFile>();

                for (int i = 0; i < images.length; i++) {
                  var path = await FlutterAbsolutePath.getAbsolutePath(images[i].identifier);

                }   

              },
