flutter - 为什么 Tapbar 空间不够？

Question

你能告诉我为什么底部空间不够吗？我给了容器足够的高度，但即使增加到 500，错误也不会消失。我的错误是什么？

我的代码-

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')
                     ],
                   ),),

为您的选项卡提供高度

DefaultTabController(
               length: 5,
               child: SingleChildScrollView(
                 child: Container(
               height: 150,  // may remove
               child:  TabBar(
                 height: 150, // give height
                 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')
                     ],
                   ),),
