Does Android LazyVerticalGrid support swipe to dismiss-CodePudding

In my latest Android compose project I had swipe to dismiss working fine for LazyColumn.

I have now made a refactor and replaced all my LazyColumns with LazyVerticalGrids.

Everything works as expected with LazyVerticalGrid apart from swipe to dismiss

when I swipe an item from my LazyVerticalGrid with one column it works fine

However when i swipe an item from my LazyVerticalGrid with multiple columns it throws the following exception:-

java.lang.IllegalArgumentException: Failed requirement.

is it possible to swipe from a multi column LazyVerticalGrid?

CodePudding user response：

No, you can't do that with the standard implementation. There isn't really a design pattern where a swipe-to-dismiss makes any sense in a context of a grid.

But you can probably make your own custom implementation, if it's something that you really want to do (but again, beware of the fact that from a user's standpoint, they probably don't expect that functionality to exist there). Instead of a grid, you can use a combination of LazyColumn and a Row, and then use Modifier.swipeable on each column item.

Alternatively, if you only want to remove each row without giving the user other actions to pick from, you're probably better off just creating a button that gets rid of each row (something like an "X" in the top-right corner of each row)
