layout_motion 0.3.1

Automatic FLIP layout animations for Flutter. Wrap any Column, Row, Wrap, or Stack to animate add, remove, and reorder with zero configuration.

0.3.1

• FIX: Dispose CurvedAnimation objects before their parent controllers to prevent listener leaks
• FIX: Defer _entries.remove() in exit status listener to avoid map mutation during iteration
• FIX: Replace per-frame setState in move animations with scoped AnimatedBuilder rebuilds
• Guard status listeners against double-disposal when animations race
• Extract AnimatedChildEntry.idle() factory to deduplicate entry creation
• Update README: add Stack references, moveThreshold/transitionDuration to API table, bump version

0.3.0

• FIX: Key validation now throws ArgumentError in release builds (was assert-only)
• Add configurable moveThreshold parameter to control sub-pixel move filtering
• Add transitionDuration parameter for independent enter/exit animation timing
• Add Stack layout support
• Improve AnimatedChildEntry test coverage (isAnimating, dispose())
• Add DiffResult.toString() and ChildSnapshot.hashCode coverage tests

0.2.1

• Add scale parameter assertions to ScaleIn/ScaleOut constructors
• Add clarifying code comments for reversed animation and listener patterns
• Add README badges, migration guide, troubleshooting, and accessibility docs
• Add Row usage example to README
• Add Row layout demo to example app
• Add GitHub Actions CI and docs workflows
• Add RTL (right-to-left) tests
• Add performance tests with large child counts

0.2.0

• BREAKING: Rename ScaleIn.beginScale → ScaleIn.scale and ScaleOut.endScale → ScaleOut.scale for consistent parameter naming
• Extract move-animation threshold to named constant _moveThreshold with documentation
• Add comprehensive transition tests (FadeIn/Out, SlideIn/Out, ScaleIn/Out, custom transitions)
• Add move animation tests (reorder, interruption, sub-pixel threshold, Row support, combined add/remove+move)

0.1.0

• Initial release
• MotionLayout widget with FLIP animation engine
• Supports Column, Row, and Wrap layouts
