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 the locale and ignored parameter are ignored, as the data for all locales is directly available.

jsonDecodeAsList<T extends Object?>(String json, [List<T> defaultValue = const []]) → List<T>

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>?

A null object with a defined type of List<T>?

nullOfMap<K, V>() → Map<K, V>?

A null object with a defined type of Map<K, V>?

nullOfSet<T>() → Set<T>?

A null object with a defined type of Set<T>?

uuid({DateTime? baseTime, bool reverse = false}) → String

Generate and retrieve the UUID for Version 7.

wait(Iterable futures) → Future<void>

Wait until all Futures given in futures are completed.

Typedefs
