flutter tab页面切换练手，手势滑动、禁止滑动、page切换动画，禁止切换动画。_flutter tabcontroller 现在左右滑动

1：AppBar、TabBar、TabBarView实现页面切换，点击tab后tabBarView有左右切换动画，滑动page联动tabBar

class DevicePage extends StatefulWidget {
  const DevicePage({super.key});
 
  @override
  State<DevicePage> createState() => _DeviceState();
}
 
class _DeviceState extends State<DevicePage>
    with SingleTickerProviderStateMixin {
  TabController? _tabController;
 
  List<Tab> tabs = [
    const Tab(
      text: '设备类型',
    ),
    const Tab(
      text: '设备规格',
    ),
    const Tab(
      text: '设备台账',
    ),
  ];
  int _cuttentIndex = 0;
  List<Widget> tabViews = [
    const TabDeviceType(),
    const TabDeviceSpecs(),
    const TabDeviceLedger()
  ];
 
  @override
  void initState() {
    super.initState();
    _tabController = TabController(length: tabs.length, vsync: this);
  }
 
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        automaticallyImplyLeading: false,
        backgroundColor: AppColors.baseColor,
        centerTitle: true,
        title: TabBar(
          controller: _tabController,
          tabs: tabs,
          isScrollable: false,
          labelStyle: TextStyle(
              color: Colors.white,
              fontSize: 16.sp,
              fontWeight: FontWeight.bold),
          unselectedLabelStyle: TextStyle(
              color: const Color(0x99FFFFFF),
              fontSize: 15.sp,
              fontWeight: FontWeight.normal),
          indicatorColor: Colors.white,
          dividerHeight: 0,
          indicatorPadding: EdgeInsets.only(top: 3.h),
          indicator:
              MyCustomIndicator(indWidth: 13.w, indHeight: 3.w, radius: 2.w),
          // onTap:(int index){   针对点击tab page无切换动画
          //   _cuttentIndex = index;
          //   print('index = $index');
          //   setState(() {}); //刷新状态
          // },
        ),
      ),
      body: TabBarView(
        controller: _tabController,
        children: tabViews,
        // physics: new NeverScrollableScrollPhysics(),  //禁止页面左右手势滑动
      ),
      // body: tabViews[_cuttentIndex],
    );
  }
}

2:只tab点击切换，带page切换动画，关闭page手势切换。

3:关闭Tab点击切换动画
