Flutter升級到2.10后無法編譯的錯誤解決方案：The minCompileSdk (31) specified in a compileSdkVersion (android-30).

最近升級了Flutter到2.10版本，發現無法編譯，錯誤如下，然后安裝了Android SDK31也依然無法解決，通過研究網絡上的方案，解決如下：

1，升級Gradle到7.4.2，在VScode終端運行gradle init重建gradle環境（因為項目在升級前建立，gradle版本是6.2）,。

2，修改項目下面的Android目錄下面的build.gradle 里面的 ext.kotlin_version = '1.6.20'到最新版本。

3，修改項目目錄下面APP里面的build.gradle里面的 targetSdkVersion 31好像沒有意義，30,31都沒有問題。

 

4，沒有修改flutter\packages\flutter_tools\gradle\flutter.gradle文件，因為里面已經是31版本了。

 把kotlin的版本修改為最新版：1.6.20

buildscript {

    ext.kotlin_version = '1.6.20'

    repositories {

        google()

        mavenCentral()

    }
