SimplestServiceLocator class final

Implements ISimplestServiceLocator to provide a service locator with singleton, lazy singleton, and factory capabilities.

Constructors

SimplestServiceLocator.instance()

Returns the singleton instance of SimplestServiceLocator. Creates a new instance if none exists.

factory

Properties

hashCode → int

The hash code for this object.

no setter, inherited

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

Methods

clear() → void

Clears all registered services.

get<T extends Object>({String? name}) → T

Retrieves a service of type T. If the service is not found, throws ServiceNotRegisteredException.

getAsync<T extends Object>({String? name}) → Future<T>

Retrieves a service of type T asynchronously. If the service is not found, throws ServiceNotRegisteredException.

isRegistered<T extends Object>({String? name}) → bool

Determines whether a service of type T is already registered. Returns true if the service is registered, false otherwise.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

registerFactory<T extends Object>(T factory(), {String? name}) → void

Registers a factory for creating new instances of the service T. Each call to get will invoke the provided factory to create a new instance.

registerFactoryAsync<T extends Object>(Future<T> asyncFactory(), {String? name}) → void

Registers a factory for creating new instances of the service T asynchronously. Each call to getAsync will invoke the provided asyncFactory to create a new instance.

registerLazySingleton<T extends Object>(T factory(), {String? name}) → void

Registers a lazy singleton service of type T. The service is created upon the first call to get and reused thereafter. The factory provides the method to create the service.

registerLazySingletonAsync<T extends Object>(Future<T> asyncFactory(), {String? name}) → void

Registers a lazy singleton service of type T that is created asynchronously. The service is created upon the first call to getAsync and reused thereafter. The asyncFactory provides the method to create the service asynchronously.

registerSingleton<T extends Object>(T instance, {String? name}) → void

Registers a singleton service of type T with an instance. Throws ServiceAlreadyRegisteredException if a service of type T is already registered.

toString() → String

A string representation of this object.

inherited

unregister<T extends Object>({String? name}) → bool

Unregisters a service of type T. Returns true if the service was successfully unregistered, false if it wasn't registered.

Operators

operator ==(Object other) → bool

The equality operator.

inherited

Static Methods

reset() → void

Resets the singleton instance of SimplestServiceLocator. This is particularly useful for testing.
