当我尝试flutter run时，发生以下错误：

Error: ADB exited with exit code 1
Performing Streamed Install

adb: failed to install C:\Flutter\appname\build\app\outputs\flutter-apk\app.apk: Failure [INSTALL_FAILED_OLDER_SDK: Failed parse during installPackageLI: /data/app/vmdl1847062534.tmp/base.apk (at Binary XML file line #7):    
Requires newer sdk version #31 (current version is #30)]
Error launching application on SM A127F.

这是我的build.gradle文件的一部分

defaultConfig {
        applicationId "de.domain.appname"
        minSdkVersion 31
        multiDexEnabled true
        targetSdkVersion 31
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
    }
