DInjection 🗄️

DInjection is a lightweight DI library inspired by .NET Service Collection and Service Provider.

Features

• Global services scope
• Singleton & Transient lifetimes
• Register base types
• Get all types of base
• High Performance

Examples

Basic usage:

//
final services = ServicesCollection() //
    .add((_) => ServiceA())
    .build();

//
final service = services.getOf<ServiceA>();

//
service.foo();

Global services:

//
final services = ServicesCollection() //
    .add((_) => ServiceA())
    .build()
    .setGlobal();

//
functionWithNoParameters();

//
void functionWithNoParameters() {
  final service = gServices.getOf<ServiceA>();
  service.foo();
}

Base type :

//
final services = ServicesCollection() //
    .base<BaseServiceA>((base) => base.add((services) => ServiceA()))
    .build();

//
final service = services.getOf<BaseServiceA>();

//
service.foo();

Get all types of base :

//
final services = ServicesCollection() //
      .base<BaseServiceA>((base) => base //
          .add((services) => ServiceA())
          .add((services) => ServiceB()))
      .build();

//
final base = services.getManyOf<BaseServiceA>();

//
for (var b in base) {
  b.foo();
}
