在flutter包含高分辨率图像的页面视图中，当我滑动到新图像时，flutter会占用越来越多的内存。如何解决这个问题？
这是我的主要.dart文件。

class MyHomePage extends StatefulWidget {
  const MyHomePage({super.key, required this.title});

  final String title;

  @override
  State<MyHomePage> createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  int _counter = 0;
  final List<String> urls = [

  ];

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text(widget.title),
      ),
      body: PageView.builder(
        itemCount: urls.length,
        itemBuilder: (context, index) {
          return Image(image: NetworkImage(urls[index]));
        },
      ),
    );
  }
}

滑动图像后，flutter使用大约1.7 GB内存。
