Tracking whether modals are open

[k5yan]

I came across similar topics, but didn't find a good solution.

In my application, I decided to handle back clicks in the Android navigation bar so as not to exit the application if the modal window is open. That is - the user presses "back": is the modals open ? close window : close the application. In my application, this functionality had to be written in six different components, due to the fact that I cannot track it :(

I would like to implement one handler function in the main component, but I lack the tools.

My suggestions:

1. release a method that will return whether modals are open in the form true\false.

2. add the return value for dismissAll. In the same form - true\false, whether the windows were closed, it seems to me simpler and would be very useful.

That is, I could call this function and build on the return value.

I will be glad if you consider my request/idea
