lateinit property initialState has not been initialized

Hi,

I encountered a problem with CircularProgressButton I wanted to try the behavior of my button, so I called startAnimation() in the onCreate() but I get this exception : lateinit property initialState has not been initialized If I call it after (like in an onClickListener) it works fine

As sample I used a simple project with an empty activity :

class MainActivity : AppCompatActivity() {

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        button.startAnimation()
    }
}

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
	xmlns:app="http://schemas.android.com/apk/res-auto"
	xmlns:tools="http://schemas.android.com/tools"
	android:layout_width="match_parent"
	android:layout_height="match_parent"
	tools:context=".MainActivity">

	<br.com.simplepass.loadingbutton.customViews.CircularProgressButton
		android:id="@+id/button"
		android:layout_width="match_parent"
		android:layout_height="wrap_content"
		android:text="Hello World!"
		app:layout_constraintBottom_toBottomOf="parent"
		app:layout_constraintLeft_toLeftOf="parent"
		app:layout_constraintRight_toRightOf="parent"
		app:layout_constraintTop_toTopOf="parent" />

</androidx.constraintlayout.widget.ConstraintLayout>

Use the version 2.1.3, this is fixed in that one =]

So, for those who have the same issue I found a workaround :

class MainActivity : AppCompatActivity() {

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        // This will manually initialize the 'initialState' field
        button.saveInitialState()

        button.startAnimation()
    }
}
