keyboardFor method

double keyboardFor(KeyboardVariant variant)

How tall this device's keyboard is when a field asks for variant.

The one place a variant becomes a number, so nothing downstream has to know which variants differ on which platform — an iPad answers the same height for all four, and that is a property of the iPad rather than something a caller should special-case.

Already turned: call it on the device oriented gave you.

Implementation

double keyboardFor(KeyboardVariant variant) => switch (variant) {
  KeyboardVariant.keypad => keypadKeyboard ?? keyboard,
  // Email and URL are the *same* keyboard with two keys swapped in the
  // bottom row, on every device measured. They differ in the picture and
  // not in the height.
  _ => keyboard,
};
