在控制臺執(zhí)行flutter run指令啟動flutter項目時，突然出現(xiàn)以下錯誤舞竿，懵了一下：

嘗試了幾種方式之后都還是報錯，好吧，繼續(xù)找解決方案吧坛吁，哈哈，終于找到了：
在這里 找到了解決的辦法 https://www.javaear.com/question/54472636.html
步驟如下：
（1）修改compileSdkVersion
在android/app/build.gradle下面修改compileSdkVersion 為28

(2)執(zhí)行指令清理一下之前生成的一些文件
flutter clean
(3)在控制臺重新啟動flutter項目
flutter run
好了围俘，項目終于又重新跑起來了~~~~~~~
點(diǎn)贊是最好的支持羹呵，關(guān)注是最大的鼓勵。親愛的朋友瓷们，很榮幸在簡書遇到您,若有疑問业栅，歡迎探討~~~。
