嗨，我正在使用Flutter创建登录屏幕，当我在TextField小部件上点击时，Render Flex溢出了。
我添加了SingleChildScrollView小部件，但仍显示相同的警告。我也在使用screen_util插件来标准化任何设备的大小
这是我的auth_screen.dart
import 'package:flutter/material.dart';
import 'package:flutter_screenutil/flutter_screenutil.dart';
import '../widgets/ui_elements/color_contants.dart';
import '../widgets/main_widget_elements/login_card.dart';
class NewAuthScreen extends StatefulWidget {
@override
_NewAuthScreenState createState() => _NewAuthScreenState();
}
class _NewAuthScreenState extends State<NewAuthScreen> {
bool _isSelected = false;
void _radio() {
setState(() {
_isSelected = !_isSelected;
});
}
Widget radioButton(bool isSelected) => Container(
width: 16.0,
height: 16.0,
padding: EdgeInsets.all(2.0),
decoration: BoxDecoration(
shape: BoxShape.circle,
border: Border.all(width: 2.0, color: Colors.black),
),
child: isSelected
? Container(
width: double.infinity,
height: double.infinity,
decoration:
BoxDecoration(shape: BoxShape.circle, color: Colors.black),
)
: Container(),
);
@override
Widget build(BuildContext context) {
ScreenUtil.instance = ScreenUtil.getInstance()..init(context);
ScreenUtil.instance =
ScreenUtil(width: 780, height: 1200, allowFontScaling: true);
return Scaffold(
backgroundColor: Color.fromRGBO(255, 250, 250, 2.0),
resizeToAvoidBottomPadding: true,
