我是新来的人.我添加了一个带有文本字段的表单,当我单击文本字段和键盘时,文本字段会上升.

这是我的代码:

Widget build(BuildContext context) {

MediaQueryData mediaQuery = MediaQuery.of(context);
return new Scaffold(
  body:  new Container(
      color: Colors.purple,
      constraints: new BoxConstraints.expand(),
      padding: EdgeInsets.only(top: 10.0,left: 10.0,right: 10.0, bottom: mediaQuery.viewInsets.bottom, ),
      child: SingleChildScrollView(
        child: Container(
            child: Column(
                crossAxisAlignment: CrossAxisAlignment.center,
                mainAxisAlignment: MainAxisAlignment.center,
                children: <Widget>[
                  SizedBox(height: 12.0),
                  Text(
                    'What is your Business Name?',
                    style: TextStyle(fontSize: 24.0),
                  ),
                  AppForm(),
                ],
              ),
            padding: EdgeInsets.only(left: 10.0,right: 10.0, bottom: mediaQuery.viewInsets.bottom),
            decoration: BoxDecoration(
              borderRadius: BorderRadius.all(Radius.circular(30.0)),
              color: Colors.white,
                ),
              )
          )
      ),
    );
  }

这是不打开键盘的结果: 没有键盘的图像

这是打开键盘后的图像: 打开键盘后图片

这是我的扑动医生输出.

注意：我使用Navigator.of（context）.push来推送ModalRoute，

嗨，我的页面上ModalRoute有TextFormField，但是当键盘显示时，输入正被键盘隐藏，如何解决呢？

return Container(
      child: ListView(
          children: <Widget>[
            //other widget
            SizedBox(height: _qtyAnimation.value),
            Row(
              children: <Widget>[
                Expanded(
                  child: Text(
                    "Jumlah",
                    style: TextStyle(fontWeight: FontWeight.bold),
                  ),
                ),
                SizedBox(
                  width: 145.0,
                  child: TextFormField(
                    focusNode: _qtyFocusNode,
                    controller: qty,
                    keyboardType: TextInputType.number,
                    textAlign: TextAlign.center,
                    decoration: InputDecoration(
                      contentPadding: EdgeInsets.all(0.0),
                      prefixIcon: IconButton(
                        icon: Icon(Icons.remove),
                        onPressed: () {},
                      ),
                      border: OutlineInputBorder(
                        borderSide:
                            BorderSide(color: Colors.grey, width: 0.1),
                      ),
                      suffixIcon: IconButton(
                        icon: Icon(Icons.add),
                        onPressed: () {},
                      ),
                    ),
                  ),
                ),
              ],
            ),
          ],
    );

多数民众赞成在我的代码，我尝试与focusnode和更多，仍然相同的结果请帮助我

当我选择文本字段时,将显示键盘,但键盘隐藏我选择的TextField.有人有解决方案吗？

谢谢.
