flutter TabBar左边间隔问题

TabBar设置isScrollable: true,内部标签距离左边出现大段间隔

TabBar(isScrollable: true,dividerColor: Colors.white, //设置底部隔断线条的颜色(默认灰色)tabAlignment: TabAlignment.center,//添加该设置大段间隔消失labelPadding: EdgeInsets.only(left: 10,right: 10,bottom: 5),indicator: MyCustomArcIndicator(),labelColor: JadeColors.black,labelStyle: TextStyle(fontSize: 36.sp,fontWeight: FontWeight.w600,),unselectedLabelColor: Color(0xff333333),unselectedLabelStyle: TextStyle(fontSize: 36.sp,),indicatorSize: TabBarIndicatorSize.label,controller: providerOf<MainModel>().tabController,tabs: MainModel.catList().map((e) => Text(e['name'])).toList(),)
