升级后，Flutter PlatformView 漂浮在所有其他小部件之上
这PlatformView升级之前一切正常，然后我在稳定频道上将 Flutter 更新到了 3.0.1 版本然后，突然发生了奇怪的行为。
我创建了一个 GIF 供您参考。\n奇怪的行为是：
\n- \n
- PlatformView 位于所有其他小部件之上。你可以看到
DropDownMenu它背后的事情。我尝试过使用Stack或其他小部件，但它不起作用。PlatformView 始终掌握一切。 \n - 事情变得更奇怪了。当我们使用 进入下一页时，PlatformView 会浮动在屏幕顶部
Navigator.push。正如你所看到的，它后面还有另一张图片。即使没有PlatformView即使另一页上 \n
对于 的其余实现，我按照此处的NativeView文档进行操作。
再一次，它在升级之前工作得很好。\n应该发生的事情是，除非PlatformView使用指定，否则不应位于其他小部件之上。\n当我转到下一页时，它应该位于新页面的后面，并且不应漂浮。Stack
我错过了什么吗？请告诉我。谢谢

我在 Dart 端的代码：\nmain.dart
class MyHomePage extends StatefulWidget {\n const MyHomePage({Key? key, required this.title}) : super(key: key);\n\n final String title;\n\n @override\n State<MyHomePage> createState() => _MyHomePageState();\n}\n\nclass _MyHomePageState extends State<MyHomePage> {\n late EffectController _controller;\n Uint8List? image;\n Uint8List? imageOutline;\n bool noLine = false;\n String effectValue = \'No effect\';\n String filterValue = \'No filter\';\n static const imagePath = \'assets/images/test_image.jpg\';\n static const imageOutlinePath = \'assets/images/test_image_outline.png\';\n\n void resetValues() {\n image = null;\n imageOutline = null;\n noLine = false;\n effectValue = \'No effect\';\n filterValue = \'No filter\';\n }\n\n @override\n Widget build(BuildContext context) {\n return Scaffold(\n floatingActionButton: FloatingActionButton(\n onPressed: () => Navigator.push(\n context,\n MaterialPageRoute(\n builder: (context) =>\n PreviewPage(Image.memory(imageOutline!))))),\n appBar: AppBar(\n title: Text(widget.title),\n ),\n body: Center(\n child: Column(\n mainAxisAlignment: MainAxisAlignment.center,\n children: <Widget>[\n SizedBox(\n width: 400,\n height: 400,\n child: image == null\n ? TextButton(\n onPressed: () async {\n image = (await rootBundle.load(imagePath))\n .buffer\n .asUint8List();\n imageOutline =\n (await rootBundle.load(imageOutlinePath))\n .buffer\n .asUint8List();\n setState(() {});\n },\n child: const Text("Apply Image"))\n : NativeView(\n onViewCreated: (controller) {\n _controller = controller;\n },\n image: image!,\n imageOutline: imageOutline!,\n noLine: noLine,\n width: 400,\n height: 400,\n // width and height is required for ios, CGRect is always zero, its a flutter bug\n // setting bounds manually int docs below\n // https://docs.flutter.dev/development/platform-integration/platform-views#on-the-platform-side-1\n )),\n //NOTE: image should be ready when showing NativeView\n SingleChildScrollView(\n scrollDirection: Axis.horizontal,\n padding: const EdgeInsets.fromLTRB(10, 0, 10, 0),\n child: image == null\n ? Container()\n : \n DropdownButton<String>(\n value: effectValue,\n icon: const Icon(Icons.arrow_downward_rounded),\n elevation: 16,\n style: const TextStyle(color: Colors.deepPurple),\n underline: Container(\n height: 2,\n color: Colors.deepPurpleAccent,\n ),\n onChanged: (String? newValue) {\n\n },\n items: <String>[\n \'No effect\',\n \'Item 20\',\n \'Item 19\',\n \'Item 18\',\n \'Item 17\',\n \'Item 16\',\n \'Item 15\',\n \'Item 14\',\n \'Item 13\',\n \'Item 12\',\n \'Item 11\',\n \'Item 10\',\n \'Item 9\',\n \'Item 8\',\n \'Item 7\',\n \'Item 6\',\n \'Item 5\',\n \'Item 4\',\n \'Item 3\',\n \'Item 2\',\n \'Item 1\',\n \'Item 0\',\n ].map<DropdownMenuItem<String>>((String value) {\n return DropdownMenuItem<String>(\n value: value,\n child: Text(value),\n );\n }).toList()),\n ),\n Visibility(\n visible: image != null,\n child: TextButton(\n onPressed: () {\n setState(() {\n resetValues();\n });\n },\n child: const Text("Remove Image")),\n ),\n ],\n ),\n ));\n }\n}\n这是我的flutter doctor -v
