📝 Walkthrough

Walkthrough

Three independent changes across CI workflows, sticker layer reordering, and Windows build configuration. CI workflows drop the pinned flutter-version: "3.38.1", keeping only channel: "stable". The sticker page reorder flow switches from onReorder to onReorderItem callback and simplifies _reorderLayer index logic. Windows build suppresses experimental coroutine deprecation warnings.

Changes

CI Flutter Version Unpinning

Layer / File(s)	Summary
Remove pinned Flutter version from release workflow .github/workflows/release.yml	The Setup Flutter step drops flutter-version: "3.38.1", retaining only channel: "stable".

Layer Drag-Reorder Fix

Layer / File(s)	Summary
Fix reorder callback and index logic lib/pages/sticker/sticker_page_sections.dart, lib/pages/sticker/sticker_page_layers.dart	ReorderableListView.builder wires onReorderItem: _reorderLayer instead of onReorder; _reorderLayer replaces adjusted-index calculation with an early return when oldIndex == newIndex and inserts directly at newIndex.

Windows Build Configuration

Layer / File(s)	Summary
Suppress coroutine deprecation warnings windows/CMakeLists.txt	Adds _SILENCE_EXPERIMENTAL_COROUTINE_DEPRECATION_WARNINGS global compile definition.

Poem

🐇 Hop, hop, the version pin is gone,
No 3.38.1 to hold us along!
The layers slide smoothly to their place,
onReorderItem runs the race.
Old index equals new? We simply skip—
A tidier list on every trip! 🎉
