What is the difference between main() and runApp() functions in Flutter?

The main() and runApp() functions are two essential components of a Flutter application that work together to execute the program[1][2][3].

The main() function is the entry point for Dart programs[1][2][3]. It is required for every Dart program to start execution[2]. In Flutter apps, main() should also call runApp() to start the framework[2].

On the other hand, the runApp() function is the entry point for the Flutter framework[1][2][3]. It attaches the given widget to the screen as the root of the widget tree that will be rendered[2][3]. runApp() takes a parameter, which is the base widget of all the widgets used in the application[1].

In summary:

• main() is the entry point for Dart programs, while runApp() is the entry point for the Flutter framework[1][2][3].
• Without main(), the application will not run, but Dart programs can still run without Flutter component...
