unicodeScalarValues property Null safety
final
An int with up to two Unicode scalar values generated by a single keystroke. An assertion will fire if more than two values are encoded in a single keystroke.
This is typically the character that keyCode would produce without any modifier keys. For dead keys, it is typically the diacritic it would add to a character. Defaults to 0, asserted to be not null.
Implementation
final int unicodeScalarValues;
