为 Flutter 列表添加向上和向下翻页的物理键盘支持

Question

Since Flutter 2.0, there is support for desktop hardware keys, but widgets like scrollable_positioned_list don't support it.

I found the problem is if I set primary parameter of ScrollView to true, it will accept PageUp and PageDown of physical keyboard, but the problem is I need to set ScrollController too, which can't be set with primary at same time.

Any suggestion?

(I tested it on Windows and Mac)

Answer 1

have you checked out the release notes for Flutter 2.2? They added some corrections in relation to the PageUp and the PageDown through the physical keyboard.
