flutter_simple_dependency_injection 2.0.0

flutter_simple_dependency_injection: ^2.0.0 copied to clipboard

• Stable null safety release
• BREAKING CHANGE: the deprecated method Injector.getInjector() has now been removed in favour of the factory constructor.
• Added the ability to allow the injector mapping to be reassigned at runtime using the parameter allowFutureReassignment

• Various code optimizations.

• Api now allows for method chaining so make mapping more concise.

• Silent removing of non existing mappings (without throwing exceptions).

• The Injector class now has a factory constructor. An Injector instance can be instantiated

  in a more concise way than Injector.getInjector() which is now marked as deprecated.

    // example with introduced changes
    final injector = Injector();
    injector.map<SomeType>((injector) => SomeType("0"))
            ..map<SomeType>((injector) => SomeType("1"), key: "One")
            ..map<SomeType>((injector) => SomeType("2"), key: "Two");

• Added the ability to remove a mapping and check if a mapping is present in the injector

    // the new api
    final injector = Injector.getInstance();
    injector.map<SomeType>((i) => new SomeType())
    final instance = injector.get<SomeType>();
    injector.removeMapping<SomeType>();

• Fixed various analyzer warnings

• Fixed some lint warnings

• Removed dependency on flutter
• Updated example to explain how to use dependency injection rather than service location

• Added ability to pass in additional arguments in the factory function with a new method call [mapWithParams].

    final injector = Injector.getInstance();
    injector.mapWithParams<SomeType>((i, p) => new SomeType(p["id"]))
    final instance = injector.get<SomeType>(additionalParameters: { "id": "some-id" });
    print(instance.id) // prints 'some-id'

• Added ability to get all objects of the same mapped type

    final injector = Injector.getInstance();
    injector.map<SomeType>((injector) => new SomeType("0"));
    injector.map<SomeType>((injector) => new SomeType("1"), key: "One");
    injector.map<SomeType>((injector) => new SomeType("2"), key: "Two");
    final instances = injector.getAll<SomeType>();
    print(instances.length); // prints '3'

• Improved injector interface using generic types instead of a passed in a type to key an object factory

The new api to map and get a type instance

    // the new api
    final injector = Injector.getInstance();
    injector.map<SomeType>((i) => new SomeType())
    final instance = injector.get<SomeType>();

The old api to map and get a type instance

    // the old api
    final injector = Injector.getInstance();
    injector.map(SomeType, (i) => new SomeType())
    final instance = injector.get<SomeType>(SomeType);

• Fixed up linting and file formats

• Initial release
