底部溢出 14 个像素的 RenderFlex。导致错误的相关小部件是 AlertDialog

Question

我正在创建一个对话框，当我点击编辑图标按钮时它会打开，但是当我点击文本字段输入文本时它会向我发送此错误

════════ Exception caught by rendering library ═════════════════════════════════
A RenderFlex overflowed by 14 pixels on the bottom.
The relevant error-causing widget was
AlertDialog

这是我的对话框代码

void _getSelectedRowInfo(dynamic date,dynamic timein,dynamic timeout) {
    Widget okButton = FlatButton(  
    child: Text("Submit",style: TextStyle(fontWeight: FontWeight.bold,color: Colors.blue[500],fontSize: 20),),  
    onPressed: () { 

   
    },  
  ); 
  
    AlertDialog alert = AlertDialog( 
scrollable: true,  
    //contentPadding:EdgeInsets.fromLTRB(0, 20, 0, 20),
    insetPadding: EdgeInsets.symmetric(vertical: 150),
    //contentPadding: const EdgeInsets.all(16.0),
    title: Text("Request to change time",style: TextStyle(fontWeight: FontWeight.bold,color: Colors.blue[500])),  
    
    content:Container(child: SingleChildScrollView( 
      scrollDirection: Axis.vertical,
    child:Column(children:<Widget> [
      
      TextField(
        decoration: InputDecoration(labelText: date,hintText: "Date"),
        controller:dateController ,
      ),
      TextField(
        decoration: InputDecoration(labelText: timein,hintText: "Time in"),
        controller:timeinController ,
      ),
      TextField(
        decoration: InputDecoration(labelText:timeout,hintText: "Time out"),
        controller:timeoutController ,
      ),
      
     ]), 
  )
  ),
  actions: [  
      okButton,  
      
    ],  
  );  
      showDialog(  
    context: context,  
    builder: (BuildContext context) {  
      return alert;  
    },  
  );  
 
    
  }

这是我的对话框的样子

当点击第一个文本字段时，它看起来像这样

请帮我解决一下。

Answer 1

可以将AlertDialog的scrollable参数设置为true来避免溢出：

AlertDialog(
  scrollable: true,
  insetPadding: EdgeInsets.symmetric(vertical: 150),
  title: Text("Request to change time",
              style: TextStyle(
                fontWeight: FontWeight.bold,
                color: Colors.blue[500],)),
  content: Column(children: <Widget>[
    TextField(
      decoration: InputDecoration(labelText: date, hintText: "Date"),
      controller: dateController,
    ),
    TextField(
      decoration: InputDecoration(labelText: timein, hintText: "Time in"),
      controller: timeinController,
    ),
    TextField(
      decoration:
      InputDecoration(labelText: timeout, hintText: "Time out"),
      controller: timeoutController,
    ),
  ]),
  actions: [
    ...
  ]
)
