flutter_recaptcha 0.0.3

A lightweight Flutter widget that generates and validates distorted CAPTCHA images with background noise, to secure forms and authentication flows without any external service.

0.0.3

• CaptchaWidgetState.regenerate() is now public, so a new CAPTCHA can be requested externally via a GlobalKey<CaptchaWidgetState>.
• Background CAPTCHA images are now properly disposed (ui.Image.dispose()) when a new CAPTCHA is generated or the widget is removed, preventing a memory leak on repeated regeneration.
• Internal cleanup: doc comments added to all public API members, magic numbers replaced with named constants, and an internal relative import used instead of a package: self-import.

0.0.1

Initial release.

• Added CaptchaWidget, a self-contained widget that renders a distorted, noisy CAPTCHA image and a text field for validation.
• Added CaptchaPainter, a CustomPainter used to draw the CAPTCHA text with random angles over a noisy background.
• Added an auto-regenerate refresh button and a manual "refresh" callback via onVerified.
