Before submitting your PR, there are a few things you can do to make sure it goes smoothly:

• Make sure to open a GitHub issue as a bug/feature request before writing your code! That way we can discuss the change, evaluate designs, and agree on the general idea
• Ensure the tests and linter pass
• Code coverage does not decrease (if any source code was changed)
• Appropriate docs were updated (if necessary)

Fixes #16 🦕

Unfortunately the approach of having a state object for the info window's visibility will not work as only one info window can be visible at a time. An info window's visibility is completely managed by the SDK and so I think the best approach is to expose a show/hide method on a MarkerState. I should have a PR that builds on top of this shortly.
