ioc_container 0.6.0

A Dart Ioc Container. Store and manage dependencies in one place keyed by type. It simplifies creating instances of your classes.

A Dart Ioc Container

Grab ioc_container on pub dev

Install it like this:

dart pub add ioc_container

Manage the creation of your dependencies in one place. If you've used Provider, you'll probably need an Ioc Container to compliment it. Provider is good at sneaking your dependencies in to widgets, but Ioc Container is good at creating them in the first place. Return get from your container to Provider's create builder method. Whenever Provider needs a dependency the Ioc Container will either create a new instance or grab one of the singletons for Provider.

Code in lib/, and example unit test in test/.

You can do this. It's nice.

final a = A('a');
final builder = IocContainerBuilder();
builder
  ..addSingletonService(a)
  ..add((i) => B(i.get<A>()))
  ..add((i) => C(i.get<B>()))
  ..add((i) => D(i.get<B>(), i.get<C>()));
final container = builder.toContainer();
var d = container.get<D>();
expect(d.c.b.a, a);
expect(d.c.b.a.name, 'a');
