Flutter Android 在 local.properties 文件中设置 compileSdkVersion答案

【问题描述】：

如果我在 build.gradle 中设置compileSdkVersion 33，就可以了。但它是一种硬代码，所以我尝试将它设置在local.properties 文件中。

由于我已经在该文件中设置了flutter.minSdkVersion=23，我认为flutter.compileSdkVersion=33 的工作方式相同，但事实并非如此。

细节：

local.properties 文件：

flutter.compileSdkVersion=33

build.gradle 文件：

def flutterCompileSdkVersion = localProperties.getProperty(\'flutter.compileSdkVersion\')
if (flutterCompileSdkVersion == null) {
    flutterCompileSdkVersion = flutter.compileSdkVersion
}

...

compileSdkVersion flutterCompileSdkVersion // error here
compileSdkVersion 33 // this works

错误信息：

FAILURE: Build failed with an exception.

无论如何要在 local.properties 文件中设置 compileSdkVersion 吗？

【解决方案1】：

我能够以这种方式使用 local.properties 设置它：

// in YourProject/android/app/build.gradle
...
android {  
    compileSdkVersion localProperties.getProperty('flutter.compileSdkVersion').toInteger()
    ...
}

以下没有工作

  android {
    compileSdkVersion flutter.compileSdkVersion
    ...
