You can't catch Treecko, because it's a starter pokemon. There's only one in the whole game and if you didn't choose it as your starter in Littleroot you can't catch it later.
Your best bet of getting a Shiny Treecko is either by a massive amount of Soft Resets, or getting to the Day Care and breeding the treecko with something until you get it
The only ways to get a treeko in this game is to choose it as a starter pokemon, have your friend make an egg of it and then trade it to you or trade for one.
