pull to refresh above nestedscrollview like instagram

[RezaKhajvand]

i want to set refresh on above the nestedscrollview like this (smartrefresher=>nestedscrollview with sliverappbar=>tabbarview)
there is a package named easy refresh that works on nested but has few issues
if U can make youre package like this it would be very nice.
i uploaded my screen that made by easy refresh...but as i say it has few issues that make this package unusable for larger apps.

by the way thanks for youre package.
