Hello.
I am creating a new app, and i can not find the procedure call initdata.
It is only two procedures there.
Do i need to import them?
Looks like you are new to MIT App Inventor 2.
If yes, welcome !
And to answer your question, there is no way and no need to call initdata.
Which two procedures are you talking about?
Sorry if I misinterpreted your question.
it looks like you are talking about a custom procedure
