[Bug]: 5.0.2 不兼容 PopScope
请描述遇到的问题，以及您所期望的正确的结果
在反复 push pop 时，不引发 crash
请说明如何操作会遇到上述问题
同时点击 webview 内部的按钮打开新的 webview 页面，点击左上角返回按钮并使用flutter的路由maybePop，网页事件回调由于异步延迟，会在pop中途引发 crash。
在下面填入关键复现代码
@override
Widget build(BuildContext context) {
final title = widget.title;
return PopScope(
canPop: false,
onPopInvoked: (didPop) async {
if (kDebugMode) {
print('didPop is: $didPop');
}
if (didPop) {
return;
}
final shouldPop = await _onBack();
if (context.mounted && shouldPop) {
await GetIt.I<Navigation>().pop(context); // 触发点
}
},
child: title == null ? _buildWebView() : _buildWebViewWithTitle(title),
);
}
Future<bool> _onBack() async {
final backHandler = widget.backHandler;
if (backHandler != null) {
return backHandler(_webViewController);
}
return true;
}
appBar: AppBar(
backgroundColor: appTheme(context).generalBackground,
leading: IconButton(
icon:
Icon(Icons.arrow_back_ios, color: appTheme(context).textPrimary),
onPressed: Navigator.of(context).maybePop,// 返回按钮
),
),
