React navigation has a well documented setOptions. https://reactnavigation.org/docs/navigation-prop
However I can't seem to find any method to retrieve the current options for the active navigator. Am I missing something? Or is there a reason why it may be private?
In particular I'm interested in getting the drawerType option out of Drawer navigator.
I just found these two handy methods.
nav.getCurrentOptions()
nav.addListener('options', () => {
})
they are both available on the NavigationContainerRef, which you can obtain via createNavigationContainerRef()
