Unresolved reference : isInitialized on lateinit property

Question

I would like to use the isInitialized method on a lateinit property, but I can't because the compiler underlines in red with the error "Unresolved reference"

Here is the code :

class MainViewModel: ViewModel()
{
    lateinit var myData: MutableLiveData<Data>

    fun getData() {
        if (this::myData.isInitialized)
    }
}

I can't go any further because of that error...

Here is my gradle files :

project.gradle:

kotlin_version = '1.3.72'

dependencies {
        classpath 'com.android.tools.build:gradle:3.6.3'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
}

app gradle:

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

    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk8:$kotlin_version"
    implementation "androidx.appcompat:appcompat:1.1.0"
    implementation "androidx.core:core-ktx:1.2.0"
    implementation "androidx.lifecycle:lifecycle-viewmodel-ktx:2.2.0"
    implementation "androidx.lifecycle:lifecycle-livedata-ktx:2.2.0"
    implementation "androidx.lifecycle:lifecycle-common-java8:2.2.0"

Your code seems to be fine from my end. Which class do you have the code? — Damilola Omoyiwola, Jun 03 '20 at 17:35

You might need to review your dependencies whether they correspond:

implementation 'androidx.lifecycle:lifecycle-extensions:2.2.0'
kapt 'androidx.lifecycle:lifecycle-compiler:2.2.0'
implementation 'androidx.lifecycle:lifecycle-viewmodel-ktx:2.2.0'

The compiler is very necessary.
