Placing the framelayout below the toolbar in ConstraintLayout

I'm using the following code to place the FrameLayout below the toolbar.

<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=".Dashboard">

    <androidx.appcompat.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="0dp"
        android:layout_height="?attr/actionBarSize"
        android:theme="@style/ThemeOverlay.AppCompat.ActionBar"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        app:popupTheme="@style/ThemeOverlay.AppCompat.Light">
        <RelativeLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent">
        <TextView
            android:id="@+id/app_title"
            android:paddingTop="20dp"
            android:textAppearance = "@android:style/TextAppearance.Material.Large"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="App Name"
            android:textStyle="bold"/>
      
        </RelativeLayout>
    </androidx.appcompat.widget.Toolbar>


    <FrameLayout
        android:id="@+id/container"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:layout_behavior="@string/appbar_scrolling_view_behavior" />

  

</androidx.constraintlayout.widget.ConstraintLayout>

How can I be able to position the FrameLayout to be always below the toolbar without setting margin_top as actionbarsize? I would like to have finer control over its position.

You can make the height as match constraints (0dp), and constraint it at the bottom to the parent and at the top to the Toolbar

<?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=".Dashboard">

    <androidx.appcompat.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="0dp"
        android:layout_height="?attr/actionBarSize"
        android:theme="@style/ThemeOverlay.AppCompat.ActionBar"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        app:popupTheme="@style/ThemeOverlay.AppCompat.Light">

        <RelativeLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent">

            <TextView
                android:id="@+id/app_title"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:paddingTop="20dp"
                android:text="App Name"
                android:textAppearance="@android:style/TextAppearance.Material.Large"
                android:textStyle="bold" />

        </RelativeLayout>
    </androidx.appcompat.widget.Toolbar>


    <FrameLayout
        android:id="@+id/container"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintTop_toBottomOf="@+id/toolbar" />


</androidx.constraintlayout.widget.ConstraintLayout>
