How to nest tab view as a child of column in flutter?

I don't want to add tabs as a child of app bar bottom cause my tabs are not on top. It is somewhere in the body.

So I tried the above method & also I tried wrapping it inside a nested scaffold. Both of them seems not working.

Following is what I've tried.

      body: SingleChildScrollView(
        physics: BouncingScrollPhysics(),
        child: Container(
          child: Column(children: [
            Container(
              padding: EdgeInsets.all(10),
              child: TextInput(
                placeholder: 'Search',
                leadingIcon: searchIcon,
              ),
            ),
            DefaultTabController(
              length: 3,
              child: Column(
                children: [
                  TabBar(
                    tabs: [
                      Tab(icon: Icon(Icons.directions_car)),
                      Tab(icon: Icon(Icons.directions_transit)),
                      Tab(icon: Icon(Icons.directions_bike)),
                    ],
                  ),
                  TabBarView(
                    children: [
                      Icon(Icons.directions_car),
                      Icon(Icons.directions_transit),
                      Icon(Icons.directions_bike),
                    ],
                  ),
                ],
              ),
            ),

give a height to tabcontroller and then wrap tabbarview with expanded.

body: SingleChildScrollView(
        physics: BouncingScrollPhysics(),
        child: Container(
          child: Column(children: [
            Container(
              height:10,
              padding: EdgeInsets.all(10),
            ),
            Container(
              height:100,//add height as per your need
              child:DefaultTabController(
              length: 3,
              child: Column(
                children: [
                  TabBar(
                    tabs: [
                      Tab(icon: Icon(Icons.directions_car)),
                      Tab(icon: Icon(Icons.directions_transit)),
                      Tab(icon: Icon(Icons.directions_bike)),
                    ],
                  ),
                  Expanded(
                    child:TabBarView(
                    children: [
                      Icon(Icons.directions_car),
                      Icon(Icons.directions_transit),
                      Icon(Icons.directions_bike),
                    ],
                  ),
                  ),
                ],
              ),
            ),
            ),
            ])))
