Hi Guys,

I recently started with Flutter Framework. I don't know much about this. Can anyone tell me what is the difference between main() and runApp() functions in Flutter?

Hi@akhtar,

The main() function came from Java-like languages so it's where all program started, without it, you can't write any program on Flutter even without UI.

The runApp() function should return widget that would be attached to the screen as a root of the widget Tree that will be rendered.
