This guide is woking wonderfully. I had overlooked it because the title made me think it was just about Firebase DB, not authentication. After reading it more carefully I could find the answers to make it work. I'm currently working on the implementation, but the instructions seem to still be all valid to this date.
It is possible, I believe, to use federated logins (login providers) with the REST api, but it becomes more complex, as it is not possible to, for example, sign into Google using the web component. A combination of a webviewer (with modified user agent), and use of the webviewstring, and the web component, will be required to sign in, get the 0Auth token/s then use this to authenticate in Firebase.
Regarding the @Andres_Cotes file
co.com.dendritas.Animacion.aix should appear the following blocks, which only show the ones you show, do you know if the original file could be obtained and said extension can be recovered
thank you
Hello Rod, where did you find the screenshot you showed? Or do you have an AIA file of the extension that contains the relevant blocks? Maybe what I found is an older version of the extension.
I'm in a hospital and I'll update it when I get home.
Hello, I hope you recover soon, I am new to the invention app, I saw a video on YouTube that I attached the link Crear una pantalla intro o splash screen con MIT App Inventor - YouTube where I followed the creation process and there the file that I mentioned was mentioned ( from there take the screenshot)
