launchUrl method
Opens the given url in a browser context.
This can be used to implement AuthHandlers or ApplicationVerifiers when they need to open an URL in a browser for sign in, reCAPTCHA, or other purposes.
Override this handler in setup using the launchUrl parameter if your application requires custom UI or navigation.
Implementation
void launchUrl(Uri url, {bool popup = false}) {
_installation.launchUrl(url, popup: popup);
}
