systemFontFamily property Null safety
The setting indicating the system font of the host platform.
Accessing this value returns the value contained in the
PlatformDispatcher singleton, so instead of getting it from here, you
should consider getting it from WidgetsBinding.instance.platformDispatcher instead
(or, when WidgetsBinding isn't available, from
PlatformDispatcher.instance). The reason this value forwards to the
PlatformDispatcher is to provide convenience for applications that only
use a single main window.
Implementation
String? get systemFontFamily => platformDispatcher.systemFontFamily;
