katana_functions library

Provides an interface to execute server-side processing in a type-safe manner. Actual processing on the server side is done by importing a separate adapter.

To use, import package:katana_functions/katana_functions.dart.

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.
