Flutter Container包裹Textfile有偏移

关键代码

decoration: InputDecoration(
                        isCollapsed: true,//重点，相当于高度包裹的意思，必须设置为true，不然有默认奇妙的最小高度
)

使用场景

Container(
  padding: EdgeInsets.only(left: 15,right: 15),
  alignment: Alignment.center,
  decoration: BoxDecoration(
      color: Colors.grey[200],
      borderRadius: BorderRadius.all(Radius.circular(18))
  ),
  width: Get.width-150,
  height: 35,
  child:  TextField(
    decoration: const InputDecoration(
      hintText: '请输入您想咨询的内容',
      isCollapsed: true,
      border: InputBorder.none,
    ),
    onSubmitted: (s){
      sendText(s,'text');
      setState(() {

      });
      print(s);
    },
    textInputAction:TextInputAction.send ,
    controller: _messageTextTF,
    focusNode: _focusNode,
  ),
),
