Ril*_*ick 9 user-interface maxlength textfield dart flutter
标题很好地总结了这个问题。我有一个TextField带有 a 的maxLength: 250,它看起来像这样:
有没有办法把柜台放在其他地方?最好位于发送按钮的左侧,但也可能位于 的上方和左侧TextField。有任何想法吗?谢谢!
可能没有必要,但这是我的代码:
TextField(
controller: inputTextEditingController,
focusNode: inputFocusNode,
style: TextStyle(color: Platform.isAndroid ? Colors.green : Colors.blue, height: 0.8),
maxLength: 250,
maxLines: null,
decoration: InputDecoration(
contentPadding: const EdgeInsets.fromLTRB(20, 15, 0, 15),
border: OutlineInputBorder(
borderRadius: BorderRadius.circular(28)),
focusedBorder: OutlineInputBorder(
borderSide: BorderSide(color: Platform.isAndroid ? Colors.green : Colors.blue),
borderRadius: BorderRadius.circular(28)),
suffixIcon: IconButton(
onPressed: _handleSubmitted,
icon: Padding(
padding: const EdgeInsets.fromLTRB(0, 0, 20, 0),
child: Icon(Icons.send,
color: inputFocusNode.hasFocus
? Platform.isAndroid ? Colors.green : Colors.blue
: Colors.black54),
),
),
hintText: "Say something!",
hintStyle: inputFocusNode.hasFocus
? TextStyle(color: Platform.isAndroid ? Colors.green : Colors.blue, fontSize: 16)

您需要构建自己的计数器并将其作为 TextField Widget 的 buildCounter 参数传递。
TextField(
maxLength: 250,
buildCounter: (_, {currentLength, maxLength, isFocused}) => Padding(
padding: const EdgeInsets.only(left: 16.0),
child: Container(
alignment: Alignment.centerLeft,
child: Text(currentLength.toString() + "/" + maxLength.toString())),
),
)

maxLines: null,
decoration: new InputDecoration(

border: OutlineInputBorder(),
