Best bottom navigation elements order?

I'm creating the prototype of a mobile app, and I decided to include a bottom navigation bar.

I'm trying to figure out what is the best order for the elements on the bar (in my case: home, favourites, search, checklists). I've been looking and reading some articles, but the best thing I've found is this image from this article. Also this other one, but it just talks about websites, not apps. This leads me to think that the best order is by importance (from left to right).

What do you think? How can I come up with the best order before testing with users? Is there any recommendation or best practice?
