locale property Null safety
The system-reported default locale of the device.
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.
This establishes the language and formatting conventions that window should, if possible, use to render their user interface.
This is the first locale selected by the user and is the user's primary locale (the locale the device UI is displayed in)
This is equivalent to locales.first and will provide an empty non-null
locale if the locales list has not been set or is empty.
Implementation
@override
ui.Locale get locale => platformDispatcher.locale;
