Hi!
I have a problem. I can not scroll to the top position when the call method smoothScrollToPosition(0)
in source code:

ryclerviewTopic.apply {
                layoutManager = LinearLayoutManager(context)
               enableSnapping(false)
                adapter = topicAdapter
            }

ryclerviewTopic.smoothScrollToPosition(0)

 <com.github.rubensousa.gravitysnaphelper.GravitySnapRecyclerView
                        android:id="@+id/ryclerviewTopic"
                        android:layout_width="match_parent"
                        android:layout_height="match_parent"
                        app:layout_constraintEnd_toEndOf="parent"
                        app:layout_constraintStart_toStartOf="parent"
                        app:layout_constraintTop_toTopOf="parent"
                        app:layout_behavior="@string/appbar_scrolling_view_behavior"
                        app:snapEnabled="false"
                        app:snapGravity="top"
                        app:snapMaxFlingSizeFraction="2"
                        app:snapScrollMsPerInch="50"
                        android:paddingTop="@dimen/_30dp"
                        tools:listitem="@layout/item_home_topic" />
