Benefits over singleton

[ncuillery]

I'm wondering what are the benefits of this package over plain simple Dart singletons.

With singletons, you can make an instance of a class available everywhere in your code base, by leveraging the Dart import mechanism (no global variable).

So I'm wondering why would I use get_it. So far, I see that get_it offers a better testability.

It also seems that the laziness would require a bit of boilerplate in singleton, that I wouldn't have to write with get_it

Is there anything else?

Seems like I had the same question just now 😄 (#88)

My question is a bit more concrete than yours → possible answer to your question: get_it supports a lot more than plain singletons, like named singletons, async stuff, non-lazy, etc.

Main difference to a singleton is that you can easily switch out implementations.

Furthermore:

• Singletons normally can't be reasigned or resetted
• GetIt offers besides Singletons Factories
• It suports async Singletons
• It has support for async startup synchronisation

Thanks for the explanation!
