GetIt – no BuildContext required

GetIt is an approach that uses the setState functionality to update the UI and leverages the power of dependency injection to give access to model classes to the whole application. It also doesn't require BuildContext to update and manage any states anywhere inside your application.

Note

If you want to learn more about dependency injection in general, please visit the wiki page (https://en.wikipedia.org/wiki/Dependency_injection).

Let's see how our counter example is built using GetIt.

Adding a GetIt dependency in a sample application

Create a new application using any name you want, just like we did in the previous chapters:

flutter create any_name_you_wish

You will get the same counter example application with the default setState management technique implemented to update the counter value.

Let's see how to embed GetIt into your application code:
