其实我想做成这样
但它正在成为
要使 multiple 项连续显示，您需要在 Column 中使用 Row() 小部件，之后要获得内联 widgets 的 equal 宽度，您需要在 Row 中使用 Expanded 小部件，然后您可以添加另一个小部件作为 Expanded 的子项。我已经在你的代码中制作了 changes 只是复制并粘贴下面的代码和 observe the changes 下次使用。

要使 multiple 项连续显示，您需要在 Column 中使用 Row() 小部件，之后要获得内联 widgets 的 equal 宽度，您需要在 Row 中使用 Expanded 小部件，然后您可以添加另一个小部件作为 Expanded 的子项。我已经在你的代码中制作了 changes 只是复制并粘贴下面的代码和 observe the changes 下次使用。
