flutter 输入框填充背景色

 TextField(
          decoration: InputDecoration(
                 border: InputBorder.none,//去掉输入框的下滑线
                 fillColor: Colors.white,
                 filled: true,
                 hintText: "留下你的精彩评论吧",
                 hintStyle: TextStyle(color: Colors.grey, fontSize: 13.0),
                 contentPadding: EdgeInsets.all(5.0),
                 enabledBorder: null,
                 disabledBorder: null),
                 controller: _publicController,
   ),

如果filled=true，则背景为fillColor，无需包在Container控件中
