San Luis Potosí has not adopted an official state flag. The Governor uses a flag that has the state coat of arms and its name under it "SAN LUIS POTOSÍ". Another flag also used unofficially is white with the state's coat of arms centered upon it; no added text. I could not find this second version in use by the State Government, but it is certainly used in other areas outside of this.

Coat of Arms

from Wikimedia Commons

According to the regulation on the coat of arms of the City of San Luis Potosí, the State Coat of Arms was officially approved in the Official State Newspaper on 31 January 1994 (I could not find this edition of the State Newspaper), making it the official state coat of arms. However, its origins date back to 30 May 1656, when Viceroy Francisco Fernández de la Cueva, Duke of Alburquerque granted a coat of arms to the city of San Luis Potosí. It was confirmed by King Philip IV on 17 August 1658, the title of Very Noble and Very Loyal City also being confirmed the same day. with the following description (according to a historic study from 1894:)

Of a hill with a field on a blue and gold field with two bars of silver and two of gold and the image of San Luis at its summit.

I could not find the original decree online, only publications citing text from it. It should be noted that because of the work of the mine, the Cerro de San Pedro depicted on the state's coat of arms does not exist anymore. The shield depicts gold and silver because the region was primarily known for the wealth from its mines at the time; in fact, Potosí is part of its name to reference the mines of Potosí in Bolivia, in hope that its mines would have the same wealth. The name San Luis was given because of Saint Louis IX the King of France, named the patron saint of the City and the state now carries his name.
