DurationPicker In a SingleChildScrollViewer doesn't respond to touches

If the DurationPicker is in a scrollviewer it is unusable. For instance, It's extremely difficult to get the slider circle to respond to touch.

It's almost like the touch target is the middle text and then after you've put your finger down in the middle, you can start swiping around the circle. It won't register touches if you tap directly on the blue slider circle.
