Describe the Bug After update to 4.0.0-beta.6 code that uses overlay based components such as Modals and Alerts does not compile when a callback is passed to onDidDismiss or onWillDismiss methods.

The following error is displayed: error TS2554: Expected 0 arguments, but got 1.

I also had this issue, solved it by using:

Change .onDidDismiss((data) => { to .onDidDismiss().then((data) => {

The documentation lacks some information about this, but I can understand because its still in beta 😉
