Answer 1

Try below code add childrenPadding and tilePadding

  ExpansionTile(
      childrenPadding: EdgeInsets.zero,
      tilePadding: EdgeInsets.zero,
   ),

Try to use MediaQuery.removePadding

MediaQuery.removePadding(
      removeTop: true,
      removeBottom: true,
      // removeLeft: true,
      // removeRight: true,
      context: context,
      child: ExpansionTile(
        childrenPadding: EdgeInsets.zero,
        tilePadding: EdgeInsets.zero,
      ),
    ),

Answer 2

Try this,

ListTileTheme(
   contentPadding: EdgeInsets.all(0),
   dense: true,
   horizontalTitleGap: 0.0,
   minLeadingWidth: 0,
   child: ExpansionTile(...)
)
