I'm having trouble understanding build variants in Android studio. I created an empty project and added product flavors as follows.

```
apply plugin: 'com.android.application'

android {
    compileSdkVersion 30
    buildToolsVersion "30.0.3"

    defaultConfig {
        applicationId "com.example.myapplication"
        minSdkVersion 16
        targetSdkVersion 30
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }
    flavorDimensions "version"
    productFlavors {
        demo {
            applicationIdSuffix ".demo"
        }
        full {
            applicationIdSuffix ".full"
        }
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }

}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])

    implementation 'androidx.appcompat:appcompat:1.3.0'
    implementation 'androidx.constraintlayout:constraintlayout:2.0.4'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'androidx.test.ext:junit:1.1.1'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'
}

```

I synced the project with Gradle files and I only get a demo debut variant. As per my understanding, I should get,

* demoDebug
* demoRelease
* fullDebug
* fullRelease

Am I following anything wrong? Any help is greatly appreciated.
