MessageLookupByLibrary class Null safety

This provides an abstract class for messages looked up in generated code. Each locale will have a separate subclass of this class with its set of messages. See generate_localized.dart.




hashCode int
The hash code for this object. [...]
read-only, inherited
localeName String
Subclasses should override this to return their locale, e.g. 'en_US'
messages Map<String, dynamic>
Subclasses should override this to return a list of their message implementations. In this class these are functions, but subclasses may implement them differently.
runtimeType Type
A representation of the runtime type of the object.
read-only, inherited


evaluateMessage(dynamic translation, List args) String?
Evaluate the translated message and return the translated string.
lookupMessage(String? messageText, String? locale, String? name, List<Object>? args, String? meaning, {MessageIfAbsent? ifAbsent}) String?
Return the localized version of a message. We are passed the original version of the message, which consists of a messageText that will be translated, and which may be interpolated based on one or more variables. [...]
noSuchMethod(Invocation invocation) → dynamic
Invoked when a non-existent method or property is accessed. [...]
toString() String
A string representation of this object. [...]


operator ==(Object other) bool
The equality operator. [...]
operator [](String messageName) → dynamic
Return our message with the given name

Static Methods
