当我没有在 tabBarView 的容器中给出 height 属性时，它会给出一个错误，并且当用它包装时SingleChildScrollView它是不可滚动的，并且当输入键盘被抬起时底部会溢出。但是，当我放在SingleChildScrollViewtabBar 上方时，它正在工作并且 tabBar 和 tabview 都在滚动，但我只希望 tabBarView 应该滚动而不是栏

我的底部溢出屏幕截图

我的代码

class TrackingPage extends StatefulWidget {
  @override
  _TrackingPageState createState() => _TrackingPageState();

添加一个您的代码 ListView，它可以解决您的问题，例如：

Widget build(BuildContext context) {
double height = MediaQuery.of(context).size.height;
return ListView(
        Scaffold(
         body: Container(

我希望解决你的问题！
