How do I create an alert if a user's email address or passwords are invalid?

You don't need to take care of these alert dialogs. FlutterFlow automatically shows the error messages generated in a SnackBar widget.

I get this error: The operation couldn’t be completed. Unable to locate a Java Runtime. Please visit http://www.java.com for information on installing Java.

You will need to install Java Runtime on your machine. Please visit http://www.java.com and download Java based on your OS.

Can I use an API for authentication?

At this time, authentication via an API is not supported. For more details on how to use Firebase authentication, please see these instructions.
