The getter userName was called on null

[ChiGlobal]

Please help, just got his error message

[ChiGlobal]

@Akchy hello please can you help🙏🏼

[Akchy]

@ChiGlobal Its showing the error because the username is having null value. I cant debug it as it is. Can you tell me how you got it?

[ChiGlobal]

@Akchy ok so, because of the nature of my project I split your code into two sides... one for the audience and one for the host. This might be the reason why it's having this problem, here is the code below:

this is for the host: help.txt

and this is for the audience: audience.txt

the audience have their own separate project from the host

[Akchy]

The error is from Host file, Hope you have a firebase account with cloud firestore database, because the data to store in userName is from either sharedpref or cloud firestore.

Can you check either of those? (try debugging the results each produce)

@Akchy so this is what at am getting:

[Akchy]

Hey, the screenshots are relevant. I was asking about the variable "userName"

[ChiGlobal]

@Akchy ok, will check it

[ChiGlobal]

here it is:

@ChiGlobal as mentioned before add print statements after you recieve value from shared pref or Firebase with userName. That's the error you want to know
