Flutter 在行中的卡片中将 topRight 对齐不起作用，请继续粘在左侧

Question

我有一个卡片小部件，它包含一些对齐方式。居中和左下对齐有效，但我也想在

topRight

上显示一些内容，它一直粘在左侧。

Answer 1

行上的默认

mainAxisSize

为

max

。您可以设置为

mainAxisSize: MainAxisSize.min

。

InkWell(
  onTap: () {},
  child: Container(
    margin: const EdgeInsets.symmetric(horizontal: 22, vertical: 10),
    width: MediaQuery.of(context).size.width,
    height: 180,
