Properties
Functions
-
generateCode(
int length, {int seed = 0, String charSet = "23456789abcdefghjkmnpqrstuvwxy"}) → String -
Generates and returns a random string with the number of characters given by
length
. -
initializeDateFormatting(
[String? locale, String? ignored]) → Future< void> -
This should be called for at least one
locale
before any date formatting methods are called. It sets up the lookup for date symbols. Both thelocale
andignored
parameter are ignored, as the data for all locales is directly available. -

Converts
json
to a Json-decoded List -
jsonDecodeAsMap<
T extends Object?> (String json, [Map< String, T> defaultValue = const {}]) → Map<String, T> -
Converts
json
to a Json-decoded Map<String, dynamic> object. -
jsonEncodable(
Object? o) → bool -
If this object is Json encodable,
true
is returned. -
nullOfList<
T> () → List< T> ? -
