I have a screen named "Schedule"
another is "Profiles"
From Profiles screen, a message should go to Schedule screen that “Hey, show me profile of session1 speaker” - for 8 sessions.
Now, schedule screen by-default has an image - the conference timeline. When it receives this message -
“Hey, show me profile of session1 speaker”
It should change the stack navigator title form Schedule to Profiles.
You create an app variable that you set to ANYTHING besides “Hew, show me profile of session1 speaker” and when Profiles gets the message, sets the app variable to “Hew, show me profile of session1 speaker” and calls a switch to screen Schedule. And Schedule has logic that, when it gets started, it should check for the value of that app variable and act accordingly.
