SingleChildScrollView“切割”屏幕 [英] SingleChildScrollView 'cutting' the screen

问题描述

这是我正在开发的登录页面的屏幕：

Here's a screen of the login page I am developing :

当键盘出现时，表明我有溢出现象，这似乎很正常：

When the keyboard shows up, it indicates me that there is an overflow, which seems to be normal :

在网络上进行了一些研究之后，我发现我必须使用 SingleChildScrollView 小部件，以便在键盘输入时出现，我就可以滚动。从我所看到的，我不得不将其添加到脚手架的 body 属性中。那就是我所做的，并且有效：我能够滚动并且没有更多的溢出错误消息。

After some researches on the web, I found that I had to use the SingleChildScrollView widget so that when the keyboard shows up, I'd be able to scroll. From what I've seen, I had to add it within the body property of the Scaffold. That's what I did, and it works : I'm able to scroll and no more overflow error message.

但是：如您所见，显示已被剪切：

BUT : The display has been cut as you can see :

有人知道这是哪里来的吗？

Does someone know where does that come from ?

这是我的代码

return Scaffold(
      body:
            SingleChildScrollView(child: 
        Container(
          child: Padding(
            padding: const EdgeInsets.all(10.0),
            child: Column(
              children: <Widget>[
                SizedBox(
                  height: 150,
                ),
                Container(
                  padding: EdgeInsets.only(left: 20.0, right: 20.0),
                  child: Column(
                    children: <Widget>[
                      tabBarContainer,
                      SizedBox(
                        height: 20.0,
                      ),

                      AnimatedContainer(
                        duration: Duration(seconds: 1),
                        padding: EdgeInsets.only(top: 40.0, left: 40.0, right: 40.0),
                        width: double.infinity,
                        height: _containerHeight,
                        decoration: cardDecoration,
                        child: TabBarView(
                          children: <Widget>[
                            LoginForm(),
                            RegisterForm(),
                          ],
                        )
                      ),

                    ],
                  ),
                )
              ],
            ),
          )
        )
        )
      );

编辑：我也尝试添加ConstrainedBox，如api flutter网站示例所示，但是它并没有帮助我：/

EDIT : I also tried to add the ConstrainedBox as shown in the exemple of the api flutter website, but it didn't help me :/

推荐答案

在SingleChildScrollView中用一个Expanded包裹，他自己包裹在Column中。

wrap the SingleChildScrollView with an Expanded, himself wrapped within a Column.

Column(
children:<Widget>[
   Expanded(
    child:SingleChildScrollView(...)
   )
  ]
)
