Is there possible to calculate the size of child view on each row/column?

Issues and steps to reproduce

I want to calculate the size of the child's view before its wrapped.
I've tried to use isWrapBefore() attribute on the view like
((FlexboxLayout.LayoutParams) flexView.getLayoutParams()).isWrapBefore()
so I thought I could get the last index of the child before it wrapped while using loops but it returns false.
I notice that the layout_wrapbefore attribute doesn't work if it wrapped automatically.

Expected behavior

I hope I can explain my issue better, but here is what I want to achieve.
I just want to get the size of the children on each row before its wrapped.
Ex:
[original list] a, b, c, d, e, f, g
[0] | a b c d |
[1] | e f g . |
1st row will return 4 and the 2nd one will return 3.
Any way to do that?

Version of the flexbox library

2.0.1

After all views are laid out, it's possible but it's not possible to calculate that beforehand because it depends on the size of the device.
