How to avoid multiple instances of a service in Angular Dart


It seems that each component that creates its own instance of [a] service. I don’t understand why.

I note this AngularJs 2 – multiple instance of service created, but I’m not clear on the correct solution. Do I create the service instance _myService in main:

 void main() {

and then copy it to [child] components (because I also remove MyService from the component providers)? This doesn’t seem correct, because the components reference _myService before it’s instantiated, and I have to check it for being null.




You can use factory constructor pattern like here.
