Question

在运行调试应用程序时，我遇到了一个错误，但我不知道为什么显示此错误，我尝试排除singlechildScrollview，但是出现了另一个错误，我不知道如何解决它。

我遇到的错误：

这个错误：

代码：

@override
  Widget build(BuildContext context) {
    return Scaffold(
        bottomNavigationBar: const BottomNavigation(),
        body: SafeArea(
            child: SingleChildScrollView(
          child: Container(
              padding: const EdgeInsets.symmetric(horizontal: 20),
              child: Column(
                crossAxisAlignment: CrossAxisAlignment.start,
                mainAxisSize: MainAxisSize.min,
                children: <Widget>[
                  const SizedBox(height: 35),
                  _appBar(),
                  const SizedBox(
                    height: 40,
                  ),
                  const TitleText(text: "My wallet"),
                  const SizedBox(
                    height: 20,
                  ),
                  const BalanceCard(),
                  const SizedBox(
                    height: 50,
                  ),
                  const TitleText(
                    text: "Operations",
                  ),
                  const SizedBox(
                    height: 10,
                  ),
                  _operationsWidget(),
                  const SizedBox(
                    height: 40,
                  ),
                ],
              )),
        )));
  }

titletext widget：

class TitleText extends StatelessWidget {
  final String text;
  final double fontSize;
  final Color color;
  const TitleText(
      {Key? key,
      this.text = '',
      this.fontSize = 18,
      this.color = LightColor.navyBlue2})
      : super(key: key);
  @override
  Widget build(BuildContext context) {
    return Text(text,
        style: GoogleFonts.mulish(
            fontSize: fontSize, fontWeight: FontWeight.w800, color: color));
  }
}

_operationswidget：

Widget _operationsWidget() {
    return Row(
      mainAxisAlignment: MainAxisAlignment.spaceAround,
      children: <Widget>[
        _icon(Icons.transfer_within_a_station, "Transfer"),
        _icon(Icons.phone, "Airtime"),
        _icon(Icons.payment, "Pay Bills"),
        _icon(Icons.code, "Qr Pay"),
      ],
    );
  }

尝试将容器包装在展开小部件中

@override
  Widget build(BuildContext context) {
    return Scaffold(
        bottomNavigationBar: const BottomNavigation(),
        body: SafeArea(

          child: Expanded(                      // like this
            child: Container(
              padding: const EdgeInsets.symmetric(horizontal: 20),
