Package Performance Hit

[b-cancel]

Before I ask my question... the explanation of what I'm trying to achieve...

• IM BUILDING a custom contact picker

I have headers for each section
A, B, etc...

I have the ability to scroll to a particular section because I know the height of
. the headers
. and how many items are in each section (all the contacts are of the same size)

At the moment I am using a CustomScrollView with a SliverFixedExtentList with a SliverChildBuilderDelegate

• THE QUESTION
  Will using this plugin to make my headers sticky affect performance by essentially shrinking wrapping each of my SliverFixedExtentList? will performance be affected any other way? If so, by how much?
