LocalePref class
User-selected UI language. null means "follow the device locale" — the
root MaterialApp.locale is left null and Flutter resolves against
AppLocalizations.supportedLocales. Persisted to SharedPreferences.
As a side effect this keeps Intl.defaultLocale in sync with the effective
language so the app's bare DateFormat call-sites format dates for the
chosen locale instead of always en_US (audit M6). When the pref is
null (follow-system), Intl.defaultLocale is cleared so intl falls back
to the platform locale.

build(
) → Future< Locale?> -
listenSelf(
void listener(AsyncValue< Locale?> ? previous, AsyncValue<Locale?> next), {void onError(Object error, StackTrace stackTrace)?}) → RemoveListener -
Listens to changes on the value exposed by this provider.
inherited
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
runBuild(
) → void -
Executes Notifier.build.
inherited
-
set(
Locale? locale) → Future< void> -
toString(
) → String -
A string representation of this object.
inherited
-
update(
FutureOr< Locale?> cb(Locale? previousState), {FutureOr<Locale?> onError(Object err, StackTrace stackTrace)?}) → Future<Locale?> -
A function to update
statefrom its previous value, while abstracting loading/error cases forstate.inherited -
updateShouldNotify(
AsyncValue< Locale?> previous, AsyncValue<Locale?> next) → bool -
A method invoked when the state exposed by this Notifier changes.
It compares the previous and new value, and return whether listeners
should be notified.
