isAltPressed property Null safety

bool isAltPressed

Returns true if a ALT modifier key is pressed, regardless of which side of the keyboard it is on.

Note that the ALTGR key that appears on some keyboards is considered to be the same as LogicalKeyboardKey.altRight on some platforms (notably Android). On platforms that can distinguish between altRight and altGr, a press of altGr will not return true here, and will need to be tested for separately.

Use isKeyPressed if you need to know which alt key was pressed.


bool get isAltPressed {
  return isKeyPressed(LogicalKeyboardKey.altLeft) || isKeyPressed(LogicalKeyboardKey.altRight);
