animated_stack_plus 1.1.2

A flexible and modern animated Floating Action Button (FAB) stack for Flutter with custom icons, builders, and smooth animations.

Changelog

1.1.2

Fixed

• Action buttons beyond the slide area (e.g. a tall column) were visible but ignored taps, because Flutter's Scaffold only hit-tests its FAB slot within the slot's bounds. The slot now sizes itself to the FAB plus the revealed actions, so every action is tappable.
• Calling closeFab after the widget was disposed (e.g. from an async action callback) no longer throws.
• The previous CurvedAnimation is now disposed when openAnimationCurve or closeAnimationCurve changes.

Changed

• Action builders now run only while the menu is open.

Documentation

• Documented that the foreground slides by scale + fabSize + actionsSpacing, that actions beyond that area overlay the foreground, and that column items should be no wider than fabSize and row items no taller than fabSize.
• README: corrected the closeAnimationCurve default (Curves.easeInOut) and the install version; the example no longer creates a GlobalKey inside build; added known limitations.
• Added library and constructor doc comments, enabled public_member_api_docs.
• Added pub.dev screenshots and refreshed topics.
• Added widget tests.

Note

• 1.1.0 renamed fabOpenIcon/fabCloseIcon to fabOpenWidget/fabCloseWidget in a minor release. That is a breaking change for anyone upgrading from 1.0.x; see the 1.1.0 entry for the migration.

1.1.1

Changes

• Replaced example assets with higher-quality, optimized versions.

1.1.0

Breaking

• Renamed fabOpenIcon and fabCloseIcon (previously restricted to the standard Icon type) to fabOpenWidget and fabCloseWidget of type Widget. This grants full visual design freedom, allowing users to pass SVGs, custom images, or complex widgets.

Added

• Added fabSize (default: 56.0) to customize Floating Action Button dimensions.
• Added actionsSpacing (default: 16.0) to define spacing between the FAB and revealed background actions.
• Introduced foregroundDimColor to render an animated fading background color overlay across the translated primary UI.

Fixed

• SnackBar Alignment Break: Repositioned background actions inside the native FloatingActionButtonLocation.endFloat slot. This resolves the alignment issue where a SnackBar or keyboard shifted the FAB upward, leaving background actions behind.
• Hit-Test Boundaries: Introduced a customized _OverflowTouchStack to bypass default bounding box clipping, ensuring action buttons that extend past physical container sizes are fully clickable.
• Visual Overflow Warnings: Removed internal hardcoded constraints (ConstrainedBox), resolving yellow-and-red striped BOTTOM OVERFLOWED visual layout errors.

Optimizations

• Switched from fractional SlideTransition math to absolute physical pixel translation via Transform.translate. This completely decouples calculations from MediaQueryData inside the build lifecycle, reducing GC allocations and performance overhead.

1.0.1

• Improved README with better structure, polished examples, and added demo GIF/video preview for web usage.

1.0.0

• Initial release
