'onRef' inyecting null ref on event handler
See original GitHub issueIssue
Hi there! The onRef
event’s handler is inyecting null
ref ({ current: null }
) when mounting the <DraggableFlatList />
component. Any ideas why could this be?
Here’s my code:
<DraggableFlatList
onRef={ref => {
alert(JSON.stringify(ref));
}} ... />

@mcama are you sure about that?
I just did a quick hacky check by logging the ref in a
setTimeout
and I see the populated ref:https://snack.expo.io/@computerjazz/swipetodelete-pkg
Remember that refs are mutable, meaning, the reference that
current
is pointing to may change. But if you try to pull the offcurrent
on first render, assign that to a variable, and expect that to change, it won’t work, because you’ll just be assigning that variable tonull
:@terrorpixel Thanks for the example! This helped a lot. Could you explain why you don’t have to declare exampleRef before onRef?
