连续的小部件没有均匀地间隔开
Widgets in a row not spacing themselves out evenly
我正在尝试制作一个小部件以在社交媒体平台上显示 post 的用户，我有一些要包含在 post 中的元素，其中之一是他在创建 post 时可能附加了外部链接。
我希望这些链接由圆形按钮表示（我已通过使用 ClipOval 设法实现）并且我希望这些椭圆排成一排 spaced从中心均匀分布。
到目前为止，我能够 space 它们的唯一方法是添加一定宽度的 SizedBox(s)。但这对于不同的 post 来说效率不高，链接的数量可能不同，因此椭圆的数量也不同。这样看起来会很乱。
我已将行覆盖在 post 的图像之上（我对其应用了 线性渐变 以使按钮可见）使用堆叠.
这是我的代码

List <String> tags = ['tag1','tag2','tag3','tag4','tag5','tag6','tag7','tag8'];

用容器包裹并赋予其全宽并移除尺寸

有一个专门的小部件可以创建 space 而不是使用 SizedBox。将 SizedBox 替换为 Spacer.
