My code is here. But snap flag does not working. How do I use SmoothAppbarLayout's snap flags?

Hi @s12u

SmoothAppBarLayout hasn't supported snap yet. During Droidcon NYC last month, Chris Banes from AppCompat team has pretty nice example about fixing fling issue of AppBarLayout. Hopefully it will be released soon. From now on, I just maintain and support other folks to work around on their issues, not implement new features. Sorry for that.

Cheers,
Henry
