smf_get_it

The SMF module of dependency injection with get_it 9. It provides the dependency injection role of SMF: the other modules of the app declare the services they generate, and this module registers them in get_it.

It adds get_it to the app and generates registerDependencies(), which the app runs before its first frame, in the form of get_it for what each service needs: singletons, lazy singletons, factories, services created asynchronously, and the services each waits for. The code that creates what the screens of a feature need takes its services with resolve in the composition file of the feature. It also generates resetDependencies(), which resets get_it: get_it disposes of the services it created, with the functions that dispose of them, in the reverse order of their registration, and removes every service, so that a test of the app can register them again.

Use with the SMF CLI

smf create asks which module provides dependency injection, and offers none as well. When a module you chose needs dependency injection, smf create adds this one by itself if it is the only module that provides it, and asks otherwise. To choose it without the question:

smf create my_app -m get_it

You don't add this package to an app yourself: smf create of the SMF CLI puts what the module generates into the app.

SMF generates apps for Flutter 3.44 or newer and Dart 3.12 or newer. It is tested on macOS, Linux and Windows.
