Chips without ChipsList ('spacebar' for new chip)

[root-ansh]

I read the Readme and understood that it uses a list of already present datawhich will be shown while the user is typing . What my requirement is an edittext, in which a user is writing something and on pressing 'spacebar', his text should become a new tag. And on pressing the back button, it should delete such tag (no need for an attached list). Something like this. (checkout the whitebox at bottom-right of the screen in desktop version of site)

How can i achieve it with this library?
