【解决方案1】：

在TabBar 中将isScrollable 设置为true

Scaffold(
      appBar: AppBar(
        bottom: TabBar(
          isScrollable: true,
          indicator: UnderlineTabIndicator(
            borderSide: BorderSide(width: 2.0),
            insets: EdgeInsets.symmetric(horizontal:10.0),),
          tabs: [
            Container(child: Tab(icon: Icon(Icons.camera_alt,))), // how to decrese the size of this tab **
            Container(child: Tab(icon: Text("CHATS"))),
            Container(child: Tab(icon: Text("STATUS"))),
            Container(child: Tab(icon: Text("CALLS"))),
          ],
        ),
      ),
    );
