Flutter 3.24 AAPT: error: resource android:attr/lStar not found.

在Android build,gradle下面，添加右边红框的代码：

subprojects {afterEvaluate { project ->if (project.plugins.hasPlugin("com.android.application") ||project.plugins.hasPlugin("com.android.library")) {project.android {compileSdkVersion 34buildToolsVersion "34.0.0"}}}
}

注意要加在下面这段代码的上面一行：

subprojects {project.buildDir = "${rootProject.buildDir}/${project.name}"project.evaluationDependsOn(':app')
}

否则会报：Cannot run Project.afterEvaluate(Closure) when the project is already evaluated.
