Flutter Recaptcha

A Flutter plugin for Google ReCaptcha powered by software Incubator.

Getting Started

This plugin requires Webview to use Google ReCaptcha. This plugin only supports Google ReCAPTCHA V2 (v1 & v3 not supported)

Obtain your own key & secret here: https://www.google.com/recaptcha

By default plugin uses https://software-incubator.github.io/flutter_recaptcha/ webpage for ReCaptcha rendering. If you would like to stay with this default, add software-incubator.github.io to allowed domains. For using your own page, specify pluginURL parameter.

Put RecaptchaV2 widget into your widget tree (Usually inside Stack widget), make sure it's placed on top of the tree and block all the behind interactions:

RecaptchaV2Controller recaptchaV2Controller = RecaptchaV2Controller();
...
RecaptchaV2(
	apiKey: "YOUR_API_KEY", // for enabling the reCaptcha
	controller: recaptchaV2Controller,
	response: (token) {
		setState(() {
		    // Can send this token to server for verification
		    print(token)
		});
	},
),

The RecaptchaV2 widget is hidden by default, you need to attach the RecaptchaV2Controller and call show() method when needed. Like this:

recaptchaV2Controller.show();

Manually hide it:

recaptchaV2Controller.hide();
