this.Parameter in File browse example

hi everyone,
i was checking the file browser example:
and i’s confused about the line of the current directory: var currentDir = this.Parameter;
I have displayed it in the log, but i have no clue what it means. I have tried to use it as a part of another app and the broswing didn’t work (no files were displayed).
is there any reference with more details about this?

note: can i use andoidPaths and iosPaths to do the exact same job? if so is there any documentation to know more about it?

Thank you.

this.Parameter holds whatever data was passed to the page during routing. See passing parameters to pages for details. I should note that it is a derived Observable, so keep in mind that you can only access it reactively.
