Add example markdown file for widget_driver #95
Description
Is your feature request related to a problem? Please describe.
When you look at packages at pub.dev then each package has an "Example" section.
There you can put some simple example use case on how to use your package.
We did not provide this for widget_driver. So it just uses the main.dart from the example app.
It would be nicer with a small example markdown there. Similar to some of the example we provide in the main readme.md for widget_driver. See here: https://github.com/bmw-tech/widget_driver/tree/master/widget_driver#usage
Describe the solution you'd like
Add a example markdown and publish a new version of widget_driver.
See the other packages in widgetdriver for inspiration. E.g: https://github.com/bmw-tech/widget_driver/blob/master/widget_driver_annotation/example/README.md
