initializeFormattingFromUrl static method
This should be called for at least one locale before any date formatting
methods are called. It sets up the lookup for date symbols using url.
The url parameter should end with a "/". For example,
"http://localhost:8000/dates/"
en_US is always loaded by default.
Implementation
static Future<void> initializeFormattingFromUrl(
String locale,
String url,
) async {
await loader.initializeFormattingFromUrl(locale, url);
}
