I have run it many times but it always shows an error. Which part is wrong?
In "login_btn.Click" blocks, change the logical block from "and" to "or".
After I modify it, it still shows undefined
I modified the FirebaseURL and Token. When I tested, I clicked the sign up button to display an error
So it's gonna be a problem with Firebase. I don't know much about this. Maybe @TIMAI2 can help you.
The error occurs when one field is empty and you click registration? And when you complete both fields?
I can't make myself such a mistake with my blocks. Works fine on standard settings.
I think it should be the firebase problem, as long as I click the sign up button, an error will appear
Check on standard firebase settings.
Perhaps. Test on a real device. Use a companion or compile an APK.
You should start this topic by saying that you are using the IOS version. IOS is under development and not everything is working properly. So far, everyone here thinks about android.
