synonyms property

Set<LogicalKeyboardKey> synonyms

Returns a set of pseudo-key synonyms for the given key.

This allows finding the pseudo-keys that also represent a concrete key so that a class with a key map can match pseudo-keys as well as the actual generated keys.

Pseudo-keys returned in the set are typically used to represent keys which appear in multiple places on the keyboard, such as the shift, alt, control, and meta keys. Pseudo-keys in the returned set won't ever be generated directly, but if a more specific key event is received, then this set can be used to find the more general pseudo-key. For example, if this is a shiftLeft key, this accessor will return the set <LogicalKeyboardKey>{ shift }.


Set<LogicalKeyboardKey> get synonyms => _synonyms[this] ?? <LogicalKeyboardKey>{};
