Added multiple style props to the button widget:
- Button styles
- The background colour can change with a hex code
- elevation (box-shadow & colour)
- There are button variant contained (solid button), outlined (only borders), text (text buttons)
- Button can have an end icon or start icon
Introducing the **Floating action button / Icon button**. Now you can use this to show small actions as icons. We have added a bunch of styling customisation to this as well. You can bind an onClick action to this and easily trigger an even. The component also automatically resizes within the widget as you scale it while maintaining the right aspect ratio.
