animate_kit

New widgets:

• AnimatedCheckmark: draws/un-draws a checkmark stroke via CustomPaint path metrics; purely visual, wrap in your own semantic control.
• RollingCounter: slot-machine digit roll on value change — rolls up for increases, down for decreases, tabular figures to prevent column shift, announces the whole number once to screen readers.
• Marquee: loops overflowing text horizontally at a configurable velocity; renders static text when it fits, static ellipsized text (no ticker) under reduce-motion, and announces the full text once.

Custom easing:

• Added a curve parameter to all 19 widgets with a meaningful transition (entrances, toggles, FlipCard, FadeSwitcher, TapScale, PulseAnimation, BounceAnimation, CountUpText, progress ring/bar). Defaults match previous behavior; for entrance widgets curve shapes the motion component while the fade stays Curves.easeOut.

New widgets (all respect MediaQuery.disableAnimations, follow the package's semantics and repaint-isolation standards):

• BlurEntrance: fade + blur-to-sharp on mount.
• FlipEntrance: fade + 3D flip in on mount (FlipAxis horizontal/vertical).
• FlipCard: state-driven 3D flip between a front and back face.
• AnimatedBlur: state-driven Gaussian blur toggle (spoilers, focus effects); skips the filter entirely when crisp.
• FadeSwitcher: cross-fade + subtle scale between changing children — an AnimatedSwitcher with production defaults and reduce-motion guard.
• TapScale: press-down scale feedback wrapping a GestureDetector.
• SpinAnimation: repeating continuous rotation for loading/sync indicators, repaint-isolated.
• LoadingDots: staggered "typing indicator" dots driven by a single shared controller (dots can't drift out of phase), repaint-isolated, no ticker under reduce-motion.
• AnimatedProgressBar: linear counterpart to AnimatedProgressRing, with the same single-announcement semantics and semanticsLabel.

New widgets (all respect MediaQuery.disableAnimations):

• RotateEntrance: fade + rotate in on mount.
• ExpandableSection: state-driven expand/collapse of a child's height, keeping the child mounted (and its state preserved) while collapsed.
• BounceAnimation: repeating vertical bounce for attention effects.
• AnimatedProgressRing: animates a circular progress ring to its value; reruns on change, with an optional centered child (e.g. a percentage label).

New widgets (all respect MediaQuery.disableAnimations):

• ScaleEntrance: fade + scale in on mount.
• StaggeredList: column of children with cascading FadeEntrance delays.
• ScaleToggle: state-driven scale between minScale and 1.0.
• SlideToggle: state-driven slide between hiddenOffset and Offset.zero.
• PulseAnimation: repeating scale + fade pulse for attention effects.
• ShakeAnimation: horizontal shake replayed whenever trigger changes.
• CountUpText: animates a number to its value; reruns on change.
• TypewriterText: reveals text character by character with optional delay.

• Initial extraction from sdraw monorepo.
• FadeEntrance: fade + slide-Y entrance animation.
• AnimatedVisibility: state-driven opacity with configurable minOpacity.
• AnimatedSurface: state-driven BoxDecoration transition.
• SkeletonBox: repeating shimmer for loading placeholder states.
• All widgets respect MediaQuery.disableAnimations.
