【中文标题】升级后 Flutter 无法在 IOS 和 Android 上运行【英文标题】：Flutter not running on both IOS and Android after upgrade 【发布时间】：2021-10-17 04:13:19 【问题描述】：这是我得到的错误。我已经尝试了这些解决方案：
-
https://fluttercorner.com/the-ios-simulator-deployment-targets-is-set-to-7-0-but-the-range-of-supported-d/
After I changed 'inheritFromWidgetOfExactType' I started getting 3 distinct new errors
他们并没有完全解决问题。
