Config: string constants for popover and alert transitions?


I want to configure the transitions of my popovers and alerts, but can’t find the appropriate string constants in the docs. The API docs for Config mention the relevant Config properties (alertEnter, alertLeave and popoverEnter, popoverLeave) but don’t say which options are available as valid values for them.

Can anybody tell me where to find them in the docs or in the github sources?

Thank you!
