tapBodyToExpand and tapBodyToCollapse are not working

[gsouf]

Hi,

I'm using version 4.1.2 and I cannot get tapBodyToCollapse and tapBodyToCollapse to work.

I used the following theme data:

 theme: ExpandableThemeData(
            tapBodyToExpand: true,
            tapHeaderToExpand: true,
            tapBodyToCollapse: true),

I confirm that passing tapHeaderToExpand will work. But the body stuff does not work.

Any idea?
