Dynamic measurement not working

First of all thanks for great lib. I’m big fan of your OSS projects!

measureRef do noting in current implementation. If we looking into official example we can see that height of row came from hardcoded array value (${rows[virtualRow.index]}px) this behaviour isn’t look like “dynamic measurement”

measureRef measures the resulting dimensions of the element, then adjusts the position of it and all other elements based on that measurement. The actual width or height of the element are not (and shouldn’t be) dictated by react virtual, otherwise it wouldn’t be dynamic at all.

Here is a better example where the dimensions are “naturally” produced by the content of the row: https://codesandbox.io/s/determined-beaver-vi2rf?file=/src/index.js

@kimroen could you please clarify?

In the project we are working on we are not passing any value there and it works… and as per the related code-sandbox you can see it “works” without it,

when you say it’s required you mean that “strange behaviour may be observed if not provided” ?

I will investigate a bit on my own to check what the “default” value would be when not provided, just to understand why everything works even when not provided I guess
