How to change title's background color in CupertinoActionSheet flutter

i am using CupertinoActionSheet for bottomsheet. But i have problem with title's background color, i need title's background to be white. I searched but couldn't find a solution for this. Can you help? is there a way?

This is my action sheet but i want like this;

My DSActionSheet code: `

return CupertinoActionSheet(
      title: Text(
        widget.title ?? "",
      ),
      message: widget.description != null ? Text(
        widget.description!,
      ) : null,
      actions: widget.actionWidgets,
      cancelButton: CupertinoActionSheetAction(
        onPressed: (){
          Navigator.pop(context);
        }, 
        child: Text(
          AppLocalizations.of(context)!.translate('cancel')!,
          style: const TextStyle(
            fontWeight: FontWeight.bold
          ),
        )
      ),
    );`

I tried wrap title with container and i gived white color to container, but this isnt work. Displayed like this:

I tried giving background color to showModalBottomSheet but then the cancel button doesn't stay separate, it didn't work either.

I solved the problem. I gave title as an actionwidget and wrap with container and color is white:

DSActionSheet(
  actionWidgets: <Widget> [
    Container(
      height: 51,
      color: Colors.white,
      child: CupertinoActionSheetAction(
        child: Text(
          AppLocalizations.of(context)!.translate("update_profile_photo")!,
          style: ThemeConstants().getActionSheetTitleTextStyle(context)
        ),
        onPressed: (){},
      ),
    ),
    Container(
      color: Colors.white,
      child: CupertinoActionSheetAction(
        onPressed: () {
          updateProfilePhoto(fromCamera: true);
        }, 
        child: Text(
          AppLocalizations.of(context)!.translate("select_from_camera")!,
        )
      ),
    ),
    Container(
      color: Colors.white,
      child: CupertinoActionSheetAction(
        onPressed: () {
          updateProfilePhoto(fromCamera: false);
        }, 
        child: Text(
          AppLocalizations.of(context)!.translate("select_from_gallery")!,
        )
      ),
    ),
    Container(
      color: Colors.white,
      child: CupertinoActionSheetAction(
        isDestructiveAction: true,
        onPressed: () {
          deleteProfilePhoto();
        }, 
        child: Text(
          AppLocalizations.of(context)!.translate("delete_profile_photo")!,
        )
      ),
    ),
  ]
)

Hope it helps someone!
