ADC2_GPIO12_CHANNEL is defined as part of esp32 library version 1.0.2. In Arduino IDE (I'm using version 1.8.15), go into Tools->Board: "ESP32 Wrover Module"->Boards Manager... . In the search bar at the top, search for esp32. When esp32 library is found, set the version to 1.0.2 then pick Install. This should solve your issue.
it is most like me but cant work it out help would be greatly appreciated
