get_it VS flutter_getx_timetracker

It's actually quite an old lib at its heart, it's the successor to get_it which is 5 yrs old and has 3500+ likes https://pub.dev/packages/get_it

Dependency injection: https://pub.dev/packages/get_it

No it is not, it had a release 3 weeks ago: https://github.com/fluttercommunity/get_it/tags so not sure what you are talking about...

Use a library like https://pub.dev/packages/get_it to save the list in a state object. When ever you get the list again, you get it from the state object. I don't know the library because I use riverpod, but it should be easy to use.

Setting up dependency injection using injectable and get_it

DI: get_it, injectable

I personally use get_it and injectable.

First thing first, I want to describe how it compares to the most popular get_it.

After some research, I found the get_it looked promising. I replaced MultiProvider with getIt singletons at the application start:

The best way to exercise is create your own simple applications which can be useful for you can be interested. For example: RSS Reader, Todo or Note app, Timetracker, some Already existing app or try create your own package and then you should also think more about your project structure and architecture ;-) When you will create all this so then you will have a good basic knowledge for another development :-)

If you want to see some code, you can look here where is my small project developed with GetX.

Here is a one simple example which I created during trying of GetX: https://github.com/mjablecnik/flutter_getx_timetracker So you can study it and judge for yourself.
