Question

在iPhone 6 plus设备上运行时，我的flutter应用程序崩溃，错误为“ 来自调试器的消息：由于内存问题终止”。当我们滚动带有图像的列表时，发生崩溃。演示崩溃的示例项目可用Here

代码

import 'package:flutter/material.dart';
import 'package:cached_network_image/cached_network_image.dart';

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: MyHomePage(title: 'Flutter Demo Home Page'),
    );
  }
}

final images = [

];

class MyHomePage extends StatefulWidget {
  MyHomePage({Key key, this.title}) : super(key: key);
  final String title;

  @override
  _MyHomePageState createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  int _counter = 0;

  @override
  Widget build(BuildContext context) {
    //var list = new List<int>.generate(60, (i) => i + 1);

    return Scaffold(
      appBar: AppBar(
        title: Text(widget.title),
      ),
      body: Center(
          child: Padding(
            padding: const EdgeInsets.all(8.0),
            child: ListView.builder(
                itemCount: images.length,
                itemBuilder: (BuildContext context, int index) {
                  return Padding(
                    padding: const EdgeInsets.all(8.0),
                    child: Column(
                      children: <Widget>[
                        Text('$index'),
                        Center(
                          child: CachedNetworkImage(
                            placeholder: (context, url) => CircularProgressIndicator(),
                            imageUrl: images[index],
                          ),
                        ),
                      ],
                    ),
                  );
                }),
          )), 
    );
  }
}

请帮助我找到一个解决方案，即使我们使用CachedNetworkImage为什么也会发生这种情况？
