我还在努力学习 Flutter。
我的主页上有一个按钮，它导航到我的 CustomWidget。（顺便说一句，它是 StepperWidget）
每当我尝试在我的小部件中添加脚手架时，它都会中断。
并给出这个错误信息。这是我的小部件树 Scaffold --> Container (height and widht) --> SingleChildScrollView ---> Stepper with steps。
我试图拆除脚手架。但这一次，每当我单击 textformfield 时，就会出现底部溢出错误。提前致谢.. //
这是我的代码；

setState(() {
currentStep = step;
