How to add empty space between columns using SingleChildScrollView Flutter

And I use a column in which there are 2 more columns and align them using the MainAxisAlignment.spaceBetween property so that there is an empty space between them. But on small screens, I don’t have enough space for all the widgets, so I decided to add a SingleChildScrollView to allow scrolling. But I ran into a problem that then the empty space between the columns disappears. Tell me how to add scrolling and keep empty space between columns?

code

Expanded(
        child: SingleChildScrollView(
          child: Column(
            mainAxisAlignment: MainAxisAlignment.spaceBetween,
            children: [
              Column(
                children: [
                  const Divider(
                    color: constants.Colors.greyMiddle,
                    height: 1,
                  ),
                  _createDrawerItem(
                      SvgPicture.asset(
                        constants.Assets.profile,
                      ),
                      'My Profile'),
                  const Divider(
                    color: constants.Colors.greyMiddle,
                    height: 1,
                  ),
                  _createDrawerItem(SvgPicture.asset(constants.Assets.profile),
                      'My Preferences'),
                  const Divider(
                    color: constants.Colors.greyMiddle,
                    height: 1,
                  ),
                  _createDrawerItem(
                      SvgPicture.asset(constants.Assets.dashboard),
                      'Dashboard'),
                  const Divider(
                    color: constants.Colors.greyMiddle,
                    height: 1,
                  ),
                  _createDrawerItem(
                      SvgPicture.asset(constants.Assets.wallet), 'Wallet'),
                  const Divider(
                    color: constants.Colors.greyMiddle,
                    height: 1,
                  ),
                ],
              ),
              // const Spacer(),
              Padding(
                padding: const EdgeInsets.only(bottom: 19),
                child: Column(
                  children: [
                    _createDrawerItem(SvgPicture.asset(constants.Assets.invite),
                        'Invite & Earn !',
                        horPadding: 11),
                    _createDrawerItem(
                        SvgPicture.asset(constants.Assets.settings), 'Settings',
                        horPadding: 11),
                  ],
                ),
              ),
            ],
          ),
        ),
      );

added SingleChildScrollView

without SingleChildScrollView

>Solution :

Column(
  children: [
    ....
  ]
),
SizedBox(
  height: 100,//custom height
),
Column(
  children: [
    ....
  ]
),

OR

Column(
  children: [
    ....
  ]
),
Padding(
    padding: EdgeInsets.only(top:100),
    Column(
      children: [
        ....
      ]
    ),
),
