當我單擊 TextField 時，我的游標和我在文本欄位中鍵入的文本不會顯示。似乎我像往常一樣做所有事情，但由于某種原因沒有顯示任何內容。請告訴我我的錯誤可能是什么？

uj5u.com熱心網友回復：
洗掉包裝您的 prefixIcon 的對齊小部件。
TextFormField(
onChanged: onChanged,
style: constants.Styles.textFieldTextStyleWhite,
cursorColor: Colors.white,
decoration: InputDecoration(
contentPadding: const EdgeInsets.only(
top: 15,
),
border: InputBorder.none,
prefixIcon: FittedBox(
fit: BoxFit.scaleDown,
child: SvgPicture.asset(
'assets/svg/logo.svg',
width: 20,
height: 20,
),
),
),
