Themed component documentation problem

[iimog]

🐛 Bug Report

The documentation for using themed components does not work as is.
One problem has already been reported: #464 but the docu is not yet updated. There is an additional problem causing the error:

TypeError: undefined is not an object (evaluating '_this$props.themedStyle')

This is caused by accessing this.props in AwesomeView even though it is a function component and not a class.

To Reproduce

Use the example code as given in docs/src/articles/design-system/use-theme-variables.md

Expected behavior

The code should work without error message and applying the passed styles.

Link to runnable example or repository (highly encouraged)

@iimog documentation is actual for 4.4.0-beta.3, which is mentioned on the website. Can you confirm you have this problem? Live examples use same code

Ah, you're about this keyword in functional components. Then yes, thanks for reporting 😄
