Flutter 更改选项卡中标签的文字样式

这看起来很直截了当。我正在尝试更改选项卡标签的文本样式。这是我的标签小部件

TabBar(

                unselectedLabelStyle:  TextStyle(fontSize: 22.0,color: Colors.red),
                labelStyle:  TextStyle(fontSize: 22.0,color: Colors.red),
                tabs: [
                  if (venue.availableService.supportsChat)Text('chat'),
                  if (venue.availableService.supportsTableService) Text('Table'),
                  if (venue.availableService.supportsCollection) Text('Collection'),
                  if (venue.availableService.supportsDelivery) Text('Delivery'),
                ],
                controller: tabController,
              ),

如何将标签连接到文本小部件

编辑： 可能应该使用选项卡小部件：

tab（文本：chat）

但仍然没有达到预期效果。

简单：

final List<Widget> myTabs = [
    Tab(
      child: Text(
        'Top Rated',
        style: TextStyle(
          fontFamily: kFontFamily,
          fontSize: 14,
          fontWeight: FontWeight.w600,
          //color: Color(0xFF818181),
          //color: kPrimaryColor,
        ),
      ),
    ),
    Tab(
      child: Text(
        'Newest',
        style: TextStyle(
          fontSize: 14,
          fontFamily: kFontFamily,
          fontWeight: FontWeight.w600,
          //color: kPrimaryColor,
        ),
      ),
    )];

TabBar(
     isScrollable: true,
     labelColor: Colors.white,
     unselectedLabelColor: Colors.black,
     controller: _controller,
     indicatorColor: kAccentColor,
     physics: BouncingScrollPhysics(),
     indicator: BoxDecoration(
       borderRadius: BorderRadius.circular(7),
       color: Color.fromRGBO(255, 87, 157, 1),
     ),
     tabs: myTabs,
),
