[Elikke-007]

版本信息

• Flutter版本：3.3.10
• flutter_smart_dialog版本：4.8.0

描述bug/需求

从浏览器点击 select widget mode 出现报错，从 Android studio 内部的 Flutter Inspector 点击 select widget mode 也是一样的报错。
报错信息如下：
One or more of the specified entries are already present in another Overlay.
'package:flutter/src/widgets/overlay.dart':
Failed assertion: line 427 pos 7: 'entries.every((OverlayEntry entry) => entry._overlay == null)'

• 'OverlayState' is from 'package:flutter/src/widgets/overlay.dart' ('../../../../flutter/packages/flutter/lib/src/widgets/overlay.dart').
  OverlayState overlay(BuildContext context) => Overlay.of(context);

flutter 3.7版本的改动是不可空了，我晚上把这个还原下吧，感觉对flutter低版本不太友好

遇到相同的问题，flutter_smart_dialog版本：4.9.7+8 ， flutter版本 3.3.9
`../../develop/flutter/.pub-cache/hosted/pub.flutter-io.cn/flutter_smart_dialog-4.9.7+8/lib/src/kit/view_utils.dart:19:55: Error: A value of type 'OverlayState?' can't be returned from a function with return type 'OverlayState' because 'OverlayState?' is nullable and 'OverlayState' isn't.

• 'OverlayState' is from 'package:flutter/src/widgets/overlay.dart' ('../../develop/flutter/packages/flutter/lib/src/widgets/overlay.dart').
  OverlayState overlay(BuildContext context) => Overlay.of(context);`
  请问有解决方案么？还是回退找个固定版本？

• 参考上面回复回退下述版本, 建议升级flutter sdk, 你的版本太老了, 现在都已经3.22.1了 @CatEatFishs
