当我第一次在Flutter官方网站上的文档帮助下安装flutter时。并且还将Android studio设置为IDE，以免产生混乱。之后，引导用户创建一个新的flutter项目，并在应用程序的样板代码上的仿真器/实际设备上运行，以计算用户按下按钮的次数。但是它每次都抛出未处理的异常。
我尝试在仿真器上运行，但也实际运行，但所有都仅抛出错误。如果有人对扑动有所了解，请帮助我，因为我是扑扑环境的新手。请参阅代码以获取更多信息。

检索ro.product.cpu.abi的设备属性时出错：
此问题与Android Studio的新更新（29）
目前有一个临时修复程序（如果您使用的是Windows）！
1。。关闭Android Studio
2。。打开CMD并输入：taskkill /f /im adb.exe
3。。下载此文件：http://dl-ssl.google.com/android/repository/platform-tools_r28.0.2-windows.zip
4。转到
C：\ Users [您的用户名] \ AppData \ Local \ Android \ Sdk
并将“ platform-tools”文件夹替换为您刚刚下载的新文件夹。
ps：（a）不要忘记保留备份（b）AppData是隐藏文件夹（一开始可能看不到）
