logicalKey property Null safety
Returns an object representing the logical key that was pressed.
This method takes into account the key map and modifier keys (like SHIFT) to determine which logical key to return.
If you are looking for the character produced by a key event, use KeyEvent.character instead.
If you are collecting text strings, use the TextField or CupertinoTextField widgets, since those automatically handle many of the complexities of managing keyboard input, like showing a soft keyboard or interacting with an input method editor (IME).
