您可能必须在列的子列之间使用sizebox()小部件。 希望这对你们有用

这是另一个涉及for循环的选项。

Column(
  children: <Widget>[
    for (var i = 0; i < widgets.length; i++)
      Column(
        children: [
          widgets[i], // The widget you want to create or place goes here.
          SizedBox(height: 10) // Any kind of padding or other widgets you want to put.
        ])
  ],
),

你可以试试这个:

import 'package:flutter/material.dart';

class CustomColumn extends Column {
  CustomColumn({
    Key? key,
    MainAxisAlignment mainAxisAlignment = MainAxisAlignment.start,
    MainAxisSize mainAxisSize = MainAxisSize.max,
    CrossAxisAlignment crossAxisAlignment = CrossAxisAlignment.center,
    TextDirection? textDirection,
    VerticalDirection verticalDirection = VerticalDirection.down,
    TextBaseline? textBaseline,
    List children = const [],
    EdgeInsetsGeometry? rowPadding,
  }) : super(
          children: children.map((e) => Padding(padding : rowPadding ?? EdgeInsets.only(bottom:12), child : e)).toList(),
          key: key,
          mainAxisAlignment: mainAxisAlignment,
          mainAxisSize: mainAxisSize,
          crossAxisAlignment: crossAxisAlignment,
          textDirection: textDirection,
          verticalDirection: verticalDirection,
          textBaseline: textBaseline,
        );
}

并调用

CustomColumn(children: [
                    item1,
                    item2,
                    item3,
                  ])

有很多方法可以做到这一点，我在这里列出了一些。

Use SizedBox and provide some height: Column( children: <Widget>[ Widget1(), SizedBox(height: 10), // <-- Set height Widget2(), ], ) Use Spacer Column( children: <Widget>[ Widget1(), Spacer(), // <-- Spacer Widget2(), ], ) Use Expanded Column( children: <Widget>[ Widget1(), Expanded(child: SizedBox.shrink()), // <-- Expanded Widget2(), ], ) Set mainAxisAlignment Column( mainAxisAlignment: MainAxisAlignment.spaceAround, // <-- alignments children: <Widget>[ Widget1(), Widget2(), ], ) Use Wrap Wrap( direction: Axis.vertical, spacing: 20, // <-- Spacing between children children: <Widget>[ Widget1(), Widget2(), ], )

将输入字段小部件提取到一个自定义小部件中，该小部件包装在填充或带有填充的容器中(假设间隔对称)。

在每个子列之间设置大小不同的盒子(如其他回答中建议的那样)是不实际或不可维护的。如果你想改变间距，你必须改变每个大小的盒子小部件。

// An input field widget as an example column child
class MyCustomInputWidget extends StatelessWidget {
  const MyCustomInputWidget({Key? key})
      : super(key: key);

  @override
  Widget build(BuildContext context) {
    // wrapping text field in container
    return Container(
      // here is the padding :)
      padding: EdgeInsets.symmetric(vertical: 10),
      child: TextField(...)
    );
  }
}

.．.然后父类中的列

column(
  children: <Widget>[
    MyCustomInputWidget(),
    SizedBox(height: 10),
    MyCustomInputWidget(),
  ],
),

显然，您希望自定义小部件具有某种构造函数来处理不同的字段参数。
