在flutter Image.network小部件中显示缩略图

import 'package:flutter/material.dart';

class ThumbnailImage extends StatelessWidget {
  final String imageUrl;
  final double width;
  final double height;

  ThumbnailImage({required this.imageUrl, required this.width, required this.height});

  @override
  Widget build(BuildContext context) {
    return FutureBuilder(
      future: Image.network(imageUrl).image.resolve(ImageConfiguration()),
      builder: (BuildContext context, AsyncSnapshot<ImageInfo> snapshot) {
        if (snapshot.connectionState == ConnectionState.done) {
          if (snapshot.hasError) {
            return Text('Error: ${snapshot.error}');
          } else {
            return Image.network(
              imageUrl,
              width: width,
              height: height,
            );
          }
        } else {
          return CircularProgressIndicator();
        }
      },
    );
  }
