after_layout VS addPostFrameCallback

[mellowcello77]

Please help me understand the difference between this package and using WidgetsBinding.instance!.addPostFrameCallback in initState. A call back works fine for me, I just don't know if I am missing something? Thanks

This is literally what the packages does:

So it's just a duplication. What for does it exist?

It's just to add a nice callback function to make it standard across your app. Also addPostFrameCallback was not known or understood by many people when we made this. So they felt it was nicer to have a package.
