Performance #

• ElasticSheetActions no longer extends InheritedNotifier; descendants that call ElasticSheetActions.of(context) are no longer rebuilt every animation frame.
• Invisible collapsed/expanded children are now skipped entirely during rendering instead of being drawn at zero opacity.
• Scoped child widgets are cached and reused across animation frames.

Bug Fixes #

• Fixed potential crash when disposing ElasticSheetController during an active pulse() animation.
• _RenderSizeReporter now captures the callback reference before scheduling a post-frame callback, preventing stale-reference issues.
• Removed redundant BoxDecoration.lerp call with a constant factor of 1.0 in the pending-state decoration builder.

API Improvements #

• expand(), collapse(), and toggle() now return TickerFuture instead of Future<void>, enabling .orCancel support.
• Added toString() to ElasticSheetConfig for better debugging output.
• Documented all empirical timing constants in ElasticSheetMotion with named constants and explanatory comments.

• Updated example/lib/main.dart with comprehensive documentation and showcase details.

• Initial public release.

• Initial public package structure for elastic_sheet
• Added runnable example/ app that consumes the package through package:elastic_sheet/elastic_sheet.dart
• Added realistic showcase scenarios and playground examples under example/
• Added package tests for fixed and dynamic expansion behavior
