2.0.0-beta.18

This is the first release of Angular 2 for Dart that is written directly in Dart, instead of generated from TypeScript.

API changes

The Provider constructor and provide() function are now more intuitive when they have a single argument.

Before, const Provider(Foo) or provide(Foo) would provide a null object. To provide a Foo object, you had to use const Provider(Foo, useClass:Foo) or provide(Foo, useClass:Foo). Now you can omit the useClass:Foo. Either of the following provides a Foo instance:

const Provider(Foo)
// or
provide(Foo)

If you want the old behavior, change your code to specify useValue:

const Provider(Foo, useValue: null)
// or
provide(Foo, useValue: null)
