1.	Write the difference between runApp() and main() in flutter.
Answer» main(): This function starts the program. Flutter does not allow us to WRITE any program WITHOUT the main() function. runApp(): Using runApp(), you are ABLE to return the widgets that are connected to the screen as a root of the widget tree that will be RENDERED on the screen. This function is called in the main function, which is the DRIVER of the app.
