scratch_to_win 0.2.2

Scratchable overlay to reveal hidden widgets with gestures and callbacks.

0.2.2

• Confetti: Added confettiDuration (default 4s, matching the old controller), confettiMinChipSize / confettiMaxChipSize (defaults 20×10 … 30×15, matching legacy confetti widget chip bounds).
• Brush: Texture stamps are clipped to a circle so the scratch tip no longer looks square when using brushTexture.
• Reveal assist: revealAssistButtonLabel is now String?; empty string hides the button even when showRevealAssistButton is true (null still defaults the label to Reveal).

0.2.1

• Replaced the confetti package with a built-in celebration overlay so particles spawn across the full width of the card (rain from above + sparkle in the upper area) instead of clustering from one corner.

0.2.0

• Simpler API: Removed velocity-based brush, brush shape options (only round stroke), and confetti tuning except confettiParticleCount. Confetti uses an omnidirectional burst with built-in gravity and timing (rain-like).
• Docs: Expanded progressGridResolution documentation on [ScratchToWin].

0.1.0

• Image overlay: overlayImage + overlayImageFit to scratch off a bitmap instead of only color/gradient.
• Brush texture: brushTexture uses the image alpha (BlendMode.dstOut) for stamp-shaped erasing; shows plain clears while the image is still decoding.
• Completion flair: playConfettiOnThreshold, confettiParticleCount, and optional playSoundOnCompletion via completionSoundAsset or completionSoundUrl (audioplayers).
• Reveal assist: showRevealAssistButton, revealAssistButtonLabel, revealAssistPadding; ScratchToWinController.revealAll().

0.0.1

• Initial release: ScratchToWin overlay with scratch gestures, progress estimate, threshold callback, haptics, and ScratchToWinController reset.
