Facing issue with row and column in flutter

问题

作为Flutter的初学者，我试图实现绿色小部件在顶部和底部以及右侧小部件部分的动态调整。此外，我正在寻求关于如何解决图像中显示的溢出问题的指导。

谢谢提前

在Flutter中遇到了有关行和列的问题。

我已经包含了我的代码，并尝试了各种方法来实现所需的设计。然而，我尚未成功完成它。是否有人可以为我提供如何实现这个设计的详细解释？

import 'package:flutter/material.dart';

class Test extends StatelessWidget {
  const Test({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return history();
  }

  Widget history() {
    return Container(
      color: Colors.lightBlue,
      child: Row(
        children: [
          leftContainer("1", Colors.green),
          Container(
            child: Column(
              crossAxisAlignment: CrossAxisAlignment.start,
              mainAxisSize: MainAxisSize.min,
              children: [
                rightContainer(
                    "Forgot to attendance punch, i was in the office from 8.30 to 6.20",
                    null,
                    false),
                rightContainer("23/01/2023-23/01/2023", Icons.date_range, true),
                rightContainer("08:30-18:20", Icons.access_time, true),
                rightContainer("Accepted", Icons.done, true),
              ],
            ),
          )
        ],
      ),
    );
  }

  Widget leftContainer(String totalDays, Color color) {
    return Container(
      padding: const EdgeInsets.only(top: 16, bottom: 16, left: 8, right: 8),
      decoration: BoxDecoration(
          color: color,
          borderRadius: const BorderRadius.only(
              topLeft: Radius.zero,
              topRight: Radius.circular(8.0),
              bottomLeft: Radius.zero,
              bottomRight: Radius.circular(8.0)),
      ),
      child: Column(
        mainAxisSize: MainAxisSize.min,
        children: [
          customTextLeftContainer(totalDays),
          customTextLeftContainer("Day"),
        ],
      ),
    );
  }

  Widget rightContainer(String value, IconData? iconData, bool iconShowed) {
    return Container(
      margin: const EdgeInsets.only(left: 8),
      child: Row(
        children: [
          iconShowed ? Icon(iconData, size: 14) : Container(),
          customTextRightContainer(value, iconShowed),
        ],
      ),
    );
  }

  Widget customTextLeftContainer(String value) {
    return Text(value,
        style: const TextStyle(
            fontFamily: 'Rubik', fontSize: 12, fontWeight: FontWeight.bold));
  }

  Widget customTextRightContainer(String value, bool iconShowed) {
    return Container(
      margin: iconShowed ? const EdgeInsets.only(left: 8) : const EdgeInsets.only(left: 0),
      child: Text(

  }
}

得分: 1

你可以使用Intrinsic小部件将Row包装起来，然后使用crossAxisAlignment: CrossAxisAlignment.stretch。

在必要的地方使用Expanded小部件。

输出:

You can wrap `Row` with `Intrinsic` Widget and use `crossAxisAlignment: CrossAxisAlignment.stretch`.
And use `Expanded` Widget where necessary.
**Output:**

**Complete code:**

Widget history() {
return Container(
margin: EdgeInsets.only(top: 32),
color: Colors.lightBlue,
child: IntrinsicHeight(

crossAxisAlignment: CrossAxisAlignment.stretch,

leftContainer("1", Colors.green),
Expanded(
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,

"23/01/2023-23/01/2023", Icons.date_range, true),
rightContainer("08:30-18:20", Icons.access_time, true),
rightContainer("Accepted", Icons.done, true),
],
),
)
],
),
),
);
}

Widget leftContainer(String totalDays, Color color) {
return Container(
padding: const EdgeInsets.only(top: 16, bottom: 16, left: 8, right: 8),
