Point it I have two StatefulWidget false as A

Question

Point it I have two StatefulWidget false as A

and B,
A wrapped a B in the state,
The basic logic is that when A gets the data, it is thrown to B(ex: new B(p1);),
Then B gets the information from the status and displays it,
However, the problem currently encountered is that B can be displayed before the data can be obtained.
As a result, B cannot display the correct information normally.

I try to use the Gblobal key to update but an error occurs. Is there any recommended method.
Or there is actually a problem with the facts? ?
