Thank you very much, it's a pleasure having a chance to help. This PR was redone anew on NS 7 branch, so we might be talking about very small conflicts.

I see there is trouble adapting this since paths for conflicting files have changes.
Is there anything I can do to help? Would merging all updates from main repo til now to my fork and reapplying changes help?

[CatchABus]

@NathanWalker I tried few attempts to rebase and think I got rid of these conflicts.
Hope this helps.

@NathanWalker @rigor789 Thank you for examining and merging this.
One minor thing I want to point out is that FlexboxLayout class may have room for a bit of cleaning. (I had set PR to draft to investigate this)

Java class has more than 1 constructors which might be unused because TypeScript class instantiates a nativeView using constructor with a single argument. https://github.com/NativeScript/NativeScript/blob/master/packages/core/ui/layouts/flexbox-layout/index.android.ts#L91
Not sure why org.nativescript.widgets.FlexboxLayout had more than 1 constructors, but I added 1 in parent class to achieve inheritance.
