September 2025 monthly summary for flutter/website focusing on delivering a key posting/docs feature: modernization of the AppDelegate sample in the platform channels docs by replacing the deprecated @UIApplicationMain with the new @main, aligning samples with Flutter app template standards.

June 2025: Implemented a regression fix for nested sliver scrolling in flutter/flutter by restoring the correct offset calculation in RenderSliverMainAxisGroup. This reverts a previous change that computed the offset based on the first item, returning to the stable behavior and ensuring proper child offsets in nested sliver groups. A regression test was added to prevent recurrence and to guard scrolling correctness across edge cases. The changes were verified with targeted tests and code review, reducing user-visible scroll glitches and improving reliability for complex UIs that rely on nested slivers.
