Flutter 使用图像包将图像分割成6块

我正在尝试一个名为

Image

[https://pub.dev/packages/image ]如下图所示，将图像分割为6个不同的部分

但当我试图调用一个方法时，它抛出了一个名为

type 'Image' is not a subtype of type 'Image' in type cast where
I/flutter (18965):   Image is from package:flutter/src/widgets/image.dart
I/flutter (18965):   Image is from package:image/src/image.dart

导入'dart:io'；
进口“包装：颤振/材料.省道”；
将“package:image/image.dart”作为imglib导入；
导入“包：image_picker/image_picker.dart”；
void main（）=>runApp（MyApp（））；
类MyApp扩展了无状态小部件{
@凌驾
小部件构建（构建上下文）{
返回材料PP(
主页：主页（），
);
}
}
类主页扩展了StatefulWidget{
@凌驾
_HomePageState createState（）=>\u HomePageState（）；
}
类_HomePageState扩展状态{
文件图像；
最终选择器=图像选择器（）；
Future getImage（）异步{
final pickedFile=wait picker.getImage（来源：ImageSource.gallery）；
设置状态（）{
image=文件（pickedFile.path）；
});
}
列表分割图像(
{图像输入图像，int水平分段计数，int垂直分段计数}）{
imglib.Image Image=inputImage作为imglib.Image；
final int xLength=（image.width/horizontalPieceCount）.round（）；
最终整数长度=（image.height/verticalPieceCount）.round（）；
List pieceList=List（）；
对于（int y=0；y<垂直分段计数；y++）
对于（int x=0；x

在这里，我试图从Gallary获得图像，并将其分为不同的部分

import 'dart:io';
import 'package:flutter/material.dart';
import 'package:image/image.dart' as imglib;
import 'package:image_picker/image_picker.dart';

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: HomePage(),
    );
  }
}

class HomePage extends StatefulWidget {
  @override
  _HomePageState createState() => _HomePageState();
}

class _HomePageState extends State<HomePage> {
  File image;
  final picker = ImagePicker();

  Future getImage() async {
    final pickedFile = await picker.getImage(source: ImageSource.gallery);

    setState(() {
      image = File(pickedFile.path);
    });
  }

  List<Image> splitImage(
      {Image inputImage, int horizontalPieceCount, int verticalPieceCount}) {
    imglib.Image image = inputImage as imglib.Image;

    final int xLength = (image.width / horizontalPieceCount).round();
    final int yLength = (image.height / verticalPieceCount).round();
    List<imglib.Image> pieceList = List<imglib.Image>();

    for (int y = 0; y < verticalPieceCount; y++)
      for (int x = 0; x < horizontalPieceCount; x++) {
        pieceList.add(
          imglib.copyCrop(image, x, y, x * xLength, y * yLength),
        );
      }

    //Convert image from image package to Image Widget to display
    List<Image> outputImageList = List<Image>();
    for (imglib.Image img in pieceList) {
      outputImageList.add(Image.memory(imglib.encodeJpg(img)));
    }

    return outputImageList;
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Column(
        children: <Widget>[
          Container(
            child: Center(
              child: image == null
                  ? Text('No image selected.')
                  : Image.file(image),
            ),
          ),
          Row(
            children: <Widget>[
              RaisedButton(
                onPressed: () {
                  getImage();
                },
                child: Text('Upload Image'),
              ),
              RaisedButton(
                onPressed: () {
                  splitImage(
                    inputImage: Image.asset("img1.jpg"),
                    horizontalPieceCount: 3,
                    verticalPieceCount: 3,
                  );
                },
                child: Text('Split Image'),
              )
            ],
          )
        ],
      ),
    );
  }
}
