Performance lag with flutter_sticky_header on Flutter 3.32.8

[jcazalELPAKOMICHI]

Hi there,

After upgrading to Flutter 3.32.8, I've noticed a significant performance lag when using the flutter_sticky_header package. The same implementation worked smoothly in previous Flutter versions.

Description:

• When scrolling a CustomScrollView with multiple SliverStickyHeader sections, the UI stutters and becomes noticeably laggy.
• This happens even with small lists.
• I’ve updated flutter_sticky_header to the latest version.
• The issue persists on both emulator and physical devices.

Steps to Reproduce:

1. Create a CustomScrollView with multiple SliverStickyHeader widgets.
2. Add a list under each sticky header.
3. Run the app on Flutter 3.32.8 and scroll.

Expected:

Smooth scrolling, as in previous Flutter versions.

Actual:

Visible lag and frame drops when scrolling.

Environment:

• Flutter: 3.32.8
• flutter_sticky_header: (latest)
• Tested on: Android Emulator & Physical Android device

Question:

Is anyone else experiencing this issue?
Any idea how to fix or optimize for Flutter 3.32.8?

Thanks!
