How to disable BottomSheetDialogFragment dragging

There is simpler way of achieving the same after material design 1.2.0 was released.

https://developer.android.com/reference/com/google/android/material/bottomsheet/BottomSheetBehavior#setdraggable

When calling from BottomSheetDialogFragment:

    override fun onCreateDialog(savedInstanceState: Bundle?): Dialog {
        val bottomSheetDialog = super.onCreateDialog(savedInstanceState) as BottomSheetDialog
        bottomSheetDialog.setOnShowListener {
            val bottomSheet = bottomSheetDialog
                .findViewById<FrameLayout>(com.google.android.material.R.id.design_bottom_sheet)

            if (bottomSheet != null) {
                val behavior: BottomSheetBehavior<*> = BottomSheetBehavior.from(bottomSheet)
                behavior.isDraggable = false
            }
        }
        return bottomSheetDialog
    }

Or with styling:

    <style name="SomeStyle" parent="Theme.MaterialComponents.Light.BottomSheetDialog">
        <item name="behavior_draggable">false</item>
    </style>

And then in onCreate of your dialog fragment:

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setStyle(DialogFragment.STYLE_NORMAL, R.style.SomeStyle)
    }
