Added #

• topics in pubspec.yaml (otp, authentication, sms, verification).

Changed #

• English pubspec.yaml description and CHANGELOG.

Fixed #

• Replaced the deprecated Color.withOpacity with a version-agnostic helper (no analyzer INFO on recent Flutter, still builds on Flutter 3.10).
• Removed files that were accidentally shipped in 0.1.0 (a leftover lib/main.dart, a stray root android/ folder, and the example app's generated platform folders). Added a .pubignore.
• README demo image now uses an absolute URL so it renders on pub.flutter-io.cn.

First release.

Added #

• OtpController — state (idle / verifying / success / error), focus, current code, reset(), fillAll() for autofill.
• OtpField — a row of animated OTP boxes: auto-focus, auto-advance, pop-in on fill, glow on focus, horizontal shake on error.
• Native autofill via AutofillHints.oneTimeCode (SMS Retriever on Android / QuickType on iOS), toggled with enableAutofill.
• OtpVerificationWidget — full state-driven screen: title / subtitle, boxes, "Resend" link, "Continue" button.
• OtpMergeView — the verification choreography: the boxes slide to the center and merge into a single card the size of one box, a pulsing loader, then a green checkmark (pop + glow) + label + button, or a red shake followed by the card splitting back into empty boxes.
• OtpFieldTheme — complete theme (per-state colors, radius, size, border, durations/curves, mergeDuration) with darkGlow and lightMinimal presets and copyWith.
• Full customization of every OtpVerificationWidget text (title, verifyingTitle, verifyingSubtitle, successTitle, successSubtitle, continueLabel, resendLabel, didntGetCodeLabel).
• Style customization: continueButtonStyle, continueButtonTextStyle, resendLabelStyle, didntGetCodeStyle.

Fixed #

• Backspace on a filled box now clears that box instead of wiping the previous box and moving focus back to it.
