CalculatorOff class Null safety
State when the calculator is off. On desktop and mobile, the calculator screen is dismissed, but that's awkward on the web, especially if the calculator is embedded in a page. So, in the web case, we turn off the LCD display, and wait in this state to see if the user presses ON at some point.
