Datepicker doesnt dismiss on back press on Android

[wigleyj]

🐛 Bug Report

If I open the datepicker component on a screen after the home screen and then hit the back button on android it takes me back to the previous screen and keeps the datepicker open. From this point on i can no longer interact with the screen because the datepicker is still open and no longer dismissable. Every press of the back button takes me back one screen, but leaves the datepicker open. i attached a screen shot of the date picker still open on a screen with no datepicker component.

To Reproduce

Steps to reproduce the behavior:

1: add datepicker component to a second, third, fourth, or later screen.
2: run app on android
3. select datepicker on next screen.
4. hit back button

Expected behavior

datepicker should close on backbutton press
