Flutter , TextField遇到的问题

一、点击空白，收起键盘

body: GestureDetector(
        behavior: HitTestBehavior.translucent,
        onTap: () {
          FocusScope.of(context).requestFocus(FocusNode()); // 收起键盘
        },
        child: Container( ... ),
      ),

二、文字不居中
问题： 文本靠上

方案： 文本已经居中（与上图有细微的差别，睁大眼睛看哈！）

设置TextField里面的decoration对应的InputDecoration中的boder参数。线框border会自动校正文字的位置。

TextField(
 InputDecoration(
  focusedBorder: OutlineInputBorder(
      borderSide: BorderSide(width: 0, color: Colors.transparent)),
  disabledBorder: OutlineInputBorder(
      borderSide: BorderSide(width: 0, color: Colors.transparent)),
  enabledBorder: OutlineInputBorder(
      borderSide: BorderSide(width: 0, color: Colors.transparent)),
  border: OutlineInputBorder(
      borderSide: BorderSide(width: 0, color: Colors.transparent)),
  contentPadding: EdgeInsets.symmetric(vertical: 0),
  ),                     
),

三、键盘弹出，底部溢出报错

方案：
外面套一层SingleChildScrollView

body: SingleChildScrollView(
              child: Column(
                children: [   ...  ],       
              ),
 ),
