onLocaleChanged property Null safety
override
A callback that is invoked whenever locale changes value.
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.
The framework invokes this callback in the same zone in which the callback was set.
See also:
- WidgetsBindingObserver, for a mechanism at the widgets layer to observe when this callback is invoked.
