MotionLayout: How to Limit the 'OnSwipe' event on a specific view instead of 'OnSwipe' on whole screen

Question

I have a motionlayout with the following 'layoutDescription' (scenes file)

    <Transition
    motion:constraintSetStart="@+id/start"
    motion:constraintSetEnd="@+id/end"
    motion:duration="1000">

    <OnSwipe
        motion:touchAnchorId="@+id/button"
        motion:touchAnchorSide="left"
        motion:dragDirection="dragLeft" />

</Transition>
<ConstraintSet android:id="@+id/start">
    <!--    ConstraintSet for starting -->
</ConstraintSet>

<ConstraintSet android:id="@+id/end">
    <!--    ConstraintSet for end -->
</ConstraintSet>

What I expect from here is if user drag the 'button' towards left side then it should perform the transition but what actually happening is when user drag left(swipe left) from any where in the screen this transition getting executed!

How to limit the animation work only when dragging the specified view?

(Im using "constraintlayout:2.0.0-beta2" )

Answer 1

Actually for onSwipe you can use touchRegionId and targetId for OnClick
