Question : Design a GUI for an application demonstrating activity to activity communication with event handling technique.
Solution :
Designing a GUI for an application in Flutter that demonstrates activity-to-activity communication with event handling
involves creating multiple screens and defining how data is passed between them.
In this example:
1.We have two screens, Screen1 and Screen2, each represented by a "StatefulWidget".
2.Screen1 contains a button to open Screen2 and displays data received from Screen2.
3.Screen2 has a text input field for the user to enter data and a button to send that data back to Screen1.
4.When the "Send Data to Screen 1" button is pressed in Screen2, it uses Navigator.pop to send the data back to Screen1.
5.Screen1 receives the data and updates the display.
6.This demonstrates a basic activity-to-activity communication pattern in Flutter using event handling.
