Question

是否有可能在GridView中拉开一个扩张拖拉机,而不是把名单上的其他物品排在一边,而将其放在首位?

如果没有,我是否可以使用任何其他植被?

我试图实现的是:

A GridView with 4 items per row. Some of those items can be expanded to show more information. Currently If I do so, the grid gets readjusted (so the expanded item opens and around it is empty) I wanted to expand the item and not move the Grid items at all. (to them perhaps Black out the screen a bit)

您可以将<代码>ExpansionTile与OverflowBox相加,并订立<代码>alignment至,并同时制定maxHala<>/code>。这里,我定在<代码>上的真正,以便<代码>ExpansionTile上的最高层的z-axis大于底层。

GridView.count(
  // ...
  reverse: true,
  children: [
    for (final number in List.generate(8, (i) => i + 1))
      OverflowBox(
        maxHeight: 1000,
        alignment: Alignment.topCenter,
        child: ExpansionTile(
          // ...
        ),
      ),
  ],
)

Try it in DartPad (make sure to shrink the output screen width so that the expanded tile will overflow through the other tile)
