◆ fl_key_event_new()

FlKeyEvent* fl_key_event_new	(	guint32	time,
		gboolean	is_press,
		guint16	keycode,
		guint	keyval,
		GdkModifierType	state,
		guint8	group
	)

FlKeyEvent: A struct that stores information from GdkEvent.

This is a class only used within the GTK embedding, created by FlView and consumed by FlKeyboardHandler. It is not sent to the embedder.

This object contains information from GdkEvent as well as an origin event object, so that Flutter can create an event object in unit tests even after migrating to GDK 4.0 which stops supporting creating GdkEvent.
