motion_number 0.1.0

Direction-aware animated numbers for Flutter. Digits roll independently in seven styles - rolling, odometer, flip, slot machine, wave, shuffle, elastic - plus percentage deltas.

Changelog

0.1.0

Initial development release. The public API is not stable yet; treat every 0.x bump as potentially breaking.

Widgets

• MotionNumber — a number whose digits animate independently when its value changes. Slots are right-anchored, so 999 → 1000 animates one new digit in rather than churning four, and separators animate rather than snap.
• MotionDelta — a direction-aware percentage or absolute delta, reading the nearest MotionNumber's transition from an inherited scope or from an explicit transition:.
• MotionNumberScope — the InheritedNotifier the two communicate through.

Motion

• Seven styles: rolling, odometer, slotMachine, flip, wave, shuffle, elastic.
• DigitMotion is the open strategy contract behind them — pass motion: to supply your own without touching the widget layer.

Formatting

• PlainFormatter, IntlFormatter (any intl NumberFormat, including en_IN lakh/crore grouping) and CompactFormatter (1.2M / 12.4L).
• NumberTextFormatter is the extension point for anything else.

Theming and accessibility

• MotionNumberTheme as a ThemeExtension, plus DirectionColors with greenUp() and redUp() presets.
• The formatted value is announced to screen readers; the 0–9 strips are excluded from semantics.
• MediaQuery.disableAnimationsOf short-circuits every slot to its final position on the first frame.
