[Flutter] How to Handle reCAPTCHA v2 Checkbox After Safetynet API Deprecation?

I'm currently using Google reCAPTCHA v2 Checkbox for user verification in my Flutter app, implemented via the grecaptcha package. Recently, I learned that Google is deprecating the SafetyNet API, so I removed it from my build.gradle file.

After this change, I'm encountering a SafetyNet API Deprecation error. To address this, I attempted to implement reCAPTCHA using a WebView in my Flutter app, but I'm now facing an "Invalid Domain for Site Key" error.

Despite these efforts, I'm still encountering the following issues:

"Invalid Domain for Site Key" error when using WebView.
