di_container 1.0.2+1

di_container library for dependency injection with the container. Easy to register and get get dependency without assign dependency's type.

main() {
  /**
   * You don't need assign type,
   * the type will auto map with type return in builder function
   *
   * With example class A and class B
   * the type map with type A because builder return a instance of A
   * the type map with type B because builder return a instance of B
   *
   * But with example abstract class C
   * you must assign type to register like this: Injector.register<C>*
