Flutter Local Captcha #
This is a fake captcha widget that helps speed up the development of prototype/demo app.
This captcha widget is designed to work locally, with minimum setup, and with basic functions like a real captcha.
This is NOT a real anti-bot solution and is NOT recommended to use in production app.
Features #
Light weight, pure dart.
Easy to use. Highly customizable.
Known Issues #
[Fixed] Terrible scrolling performance on iOS devices when Impeller is enabled. As a temporary solution, you can disable Impeller by adding the '--no-enable-impeller' flag to the 'flutter run' command.
