onLocaleChanged property
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.
