A repository full of various Kivy Examples
Each folder has its own example and can be executed with python3. Just ensure you have Kivy installed for the version of python3 you are using.
Take a look at requirements.txt to see the pip packages (with version numbers) that were used to create these examples.
You can take a look at your packages and version numbers using pip freeze in your terminal. Make sure to type that command
after you have activated your Kivy virtual environment if that is applicable.
