RubberBand Animation does not have the infinite: true property

[igbokwenu]

Hello, and thank you for creating this awesome package! Been using it for years in my projects.

The RubberBand animation is under the Attention Seekers animations, and the documentation states that

All of the following animations (Attention Seekers) can be made infinite using the infinite property (type: bool)

However, when I addthe infinite: true prop to RubberBand, I get the error:

The named parameter 'infinite' isn't defined.
Try correcting the name to an existing named parameter's name, or defining a named parameter with the name 'infinite'.dartundefined_named_parameter
