intl_local/lib/src/date_format_internal library

This contains internal implementation details of the date formatting code which are exposed as public functions because they must be called by other libraries in order to configure the source for the locale data. We don't want them exposed as public API functions in the date formatting library, so they are put in a separate library here. These are for internal use only. User code should import one of the date_symbol_data... libraries and call the initializeDateFormatting method exposed there.

Properties

cachedDateSymbols ↔ DateSymbols?

Cache the last used symbols to reduce repeated lookups.

getter/setter pair

dateTimePatterns ↔ dynamic

This holds the patterns used for date/time formatting, indexed by locale. Note that it will be set differently during initialization, depending on what implementation we are using. By default, it is initialized to an instance of UninitializedLocaleData, so any attempt to use it will result in an informative error message.

Functions

initializeDatePatterns(Function patterns) → void

Initialize the patterns dictionary. This should be passed a function that creates and returns the pattern data. We take a function so that if initializing the data is an expensive operation it need only be done once, no matter how many times this method is called.

initializeDateSymbols(Function symbols) → void

Initialize the symbols dictionary. This should be passed a function that creates and returns the symbol data. We take a function so that if initializing the data is an expensive operation it need only be done once, no matter how many times this method is called.
