why Not enough tapbar space?

Question

can you tell me why I don't have enough space at the bottom? I gave enough height to the container, but even if it is increased to 500, the error will not go away. What's my mistake?

My code -

DefaultTabController(
               length: 5,
               child: SingleChildScrollView(
                 child: Container(
               height: 150,
               child:  TabBar(
                 isScrollable: true,
                 tabs: [
                   Tab(child: Column(
                     children: [
                       InkWell(
                         onTap: () async {
                           print('asdasda');
                         },
                         child:  Container(
                           width: 71,
                           height: 71,
                           decoration: BoxDecoration(
                               color: Colors.white,
                               shape: BoxShape.circle
                           ),
                           child: IconButton(onPressed: () {}, icon: Icon(Icons.phone_iphone, size: 30, color: configColors.homeIcon,)),
                         ),
                       ),
                       Text('Phonesss')
                     ],
                   ),),

To increase the height on Tab, you need to provide height on Tab.

return Tab(
  height: 150, //this
  child: Column(
    children: [
