kWebLocationMap top-level constant Null safety

Map<String, List<LogicalKeyboardKey?>> const kWebLocationMap

A map of Web KeyboardEvent keys which needs to be decided based on location, typically for numpad keys and modifier keys. Used to provide different key objects for keys like KEY_EQUALS and NUMPAD_EQUALS.
