animated_currency_field 0.5.0

A transparent Flutter text field where typed characters bloom from a blurry rising dot into the glyph. Tuned for amount entry, works for any text.

Changelog

All notable changes to this project are documented here. This project follows Semantic Versioning.

0.5.0

Changed

• Fixed overflow error when text/digits getting outside of screen boundry.
• Fixed weird animation coming when adding 0 upfront for digit only mode.

0.4.0

Added

• DotOrigin enum (bottom / top) — the dot can now descend into the glyph from above or rise from below.
• dotExpandScale knob — the dot grows as it dissolves so it visually merges into the glyph's mass instead of fading out from a tiny point.

Changed

• Reworked the bloom phases for a silky-smooth handoff:
  • All opacity, scale, and blur envelopes use a smoothstep instead of linear lerps.
  • The dot now travels through the glyph rest position (rather than stopping below it), giving a wider overlap window where both layers share space.
  • Glyph and dot blur are coordinated — the dot softens into a cloud as the glyph sharpens out of it.
• Default values tuned for a more visible, more expressive bloom (dotSize 14→16, dotTravelDistance 0.25→0.35, startBlur 22→24, startScale 0.55→0.7, overshootScale 1.08→1.05).

0.3.0

Fixed

• Fast-backspace flicker: exiting characters now stay in their original slot and play the reverse animation in place, instead of being shuffled to a separate bucket.
• Vertical jitter when typing the first character: the row now reserves a stable height equal to the text line height regardless of content.
• Each animated character now reserves layout space equal to its final glyph so neighbors don't shift during the bloom.

Added

• showPlaceholder toggle.
• dotStartOpacity and dotTravelDistance knobs on AnimatedCharacterStyle.

Changed

• Renamed AnimatedCharacterStyle.riseDistance to glyphRiseDistance for clarity.
• Cursor height matches the glyph baseline more closely; cursor uses rounded ends.

0.2.0

Added

• animationSpeed multiplier on top of animationDuration.
• allowDecimal, maxDecimalPlaces, decimalSeparator for amount entry with smart formatting (one separator, auto-prefixed 0., capped decimals).
• allowedPattern (RegExp) for free-form character whitelisting when digitsOnly is false.
• prefixText / prefixStyle / showPrefix and matching suffix props — no need to build a Text widget for a currency symbol.
• DecimalInputFormatter is exported for reuse outside the widget.

Changed

• Numeric keyboard now opts into the decimal pad automatically when allowDecimal is true.

0.1.0

• Initial release.
• AnimatedCurrencyField with per-character rising-dot bloom animation and reverse animation on delete.
• Configurable AnimatedCharacterStyle (dot size, blur, rise distance, overshoot).
• Digits-only mode by default; opt out for arbitrary text.
• Prefix/suffix widget slots, placeholder, blinking cursor.
