intl_local/lib/src/intl_helpers library

A library for general helper code associated with the intl library rather than confined to specific parts of it.

Classes

LocaleDataReader: An abstract superclass for data readers to keep the type system happy.
MessageLookup
UninitializedLocaleData<F>: This is used as a marker for a locale data map that hasn't been initialized, and will throw an exception on any usage that isn't the fallback patterns/symbols provided.

messageLookup ↔ MessageLookup: The internal mechanism for looking up messages. We expect this to be set by the implementing package so that we're not dependent on its implementation.
getter/setter pair

canonicalizedLocale(String? aLocale) → String
computeMessageName(String? name, String? text, String? meaning) → String?: If a message is a string literal without interpolation, compute a name based on that and the meaning, if present.
initializeInternalMessageLookup(Function lookupFunction) → void: Initialize the message lookup mechanism. This is for internal use only. User applications should import message_lookup_by_library.dart and call initializeMessages
shortLocale(String aLocale) → String: Return the short version of a locale name, e.g. 'en_US' => 'en'
verifiedLocale(String? newLocale, bool localeExists(String), String? onFailure(String)?) → String?

MessageIfAbsent = String Function(String? messageText, List<Object>? args): Type for the callback action when a message translation is not found.
