Button_and_Menubar in Flutter

If you are a beginner in Flutter, then here you will learn how to create a Menubar and button.
What you will see in this article:

1. StatelessWidget
2. RaisedButton
3. Drawer
4. AppBar

I have used Codepen for writing code. Don't worry if you are new to it. Click on Flutter - code will display, and Click on Result- Final results of the code will display.

All the best. Happy Coding!!!
