        applicationId "com.inspireui.fluxstore"
        minSdkVersion 23
        targetSdkVersion 30
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
        multiDexEnabled true
        resConfigs "en"
    }

        if (project.hasProperty("android") && project.property("android").compileSdkVersion.equals("android-R")) {
            android {
