有什么简单的方法可以在flutter中显示文件夹中的任何图像吗？

import 'package:flutter/material.dart';
import 'package:flutter_file_manager/flutter_file_manager.dart';
import 'package:flutter_image/flutter_image.dart';

class ImageFolderPage extends StatefulWidget {
  @override
  _ImageFolderPageState createState() => _ImageFolderPageState();
}

class _ImageFolderPageState extends State<ImageFolderPage> {
  List<String> imagePaths = [];

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

  Future<void> getImagesFromFolder() async {
    var folderPath = '/path/to/folder'; // 替换为实际的文件夹路径
    var files = await FileManager.listFiles(folderPath);
    var imageFiles = files.where((file) => file.endsWith('.jpg') || file.endsWith('.png')).toList();
    setState(() {
      imagePaths = imageFiles;
    });
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Image Folder'),
      ),
      body: GridView.builder(
        gridDelegate: SliverGridDelegateWithFixedCrossAxisCount(
          crossAxisCount: 3,
          crossAxisSpacing: 10,
          mainAxisSpacing: 10,
        ),
        itemCount: imagePaths.length,
        itemBuilder: (context, index) {
          return Image.file(
            File(imagePaths[index]),
            fit: BoxFit.cover,
          );
        },
      ),
    );
  }
}
