Flutter 去除 tabbar 点击色

Tabbar居左

   const double _kTabHeight = 46.0;
   return PreferredSize(
      preferredSize: Size.fromHeight(_kTabHeight),
      child: TabBar(),
      //child: buildTheme(),
    );

对TabController的监听在点击Tab后会执行两次

  tabController.addListener(() {
    if (tabController.indexIsChanging) {
      print(tabController.index);
    }
  });

去除点击色

return Theme(
   data: ThemeData(
     highlightColor: Colors.transparent,
     splashColor: Colors.transparent,
   ),
   child: new TabBar(
     controller: tabController,
     tabs: <Tab>[
       new Tab(text: "首页"),
     ],
     // 去除下划线
     indicator: const BoxDecoration(),
   ),
 );
