Flutter - 3rd application - digging deeper into the toolkit

For this flutter application, I decided to create a simple shopping app.

The last week I started digging deeper into flutter and dart and as always I tried to implement everything in this application.

In my previous post I was kind of disappointed with the ways that I had to use in order to pass data between the different widgets and screens, but this time, I found something magical. Something called provider.

As always I’m not going into technical talks and explanations, I will simply mention the things that I learned so far and my impressions as a flutter beginner.

New things that I learned how to use:

The provider package. As I already mentioned – this is something amazing that is giving you the flexibility to hook it up everywhere in our applications, listen for changes and rebuild the parts that are listening to them. I also learned how to work with multiple providers
I learned a lot about state and state management. I learned how to use local and application-wide states.
I heavily used the consumer class, as it allows us to create more flexible apps.
I learned how to use and tweak the dismissible class and how to build nice dialogs.
I also learned how to use, validate and submit forms.
I learned how to send HTTP requests from a flutter application.
I learned how to use futures and why they are so useful.
I learned how to invoke the various application/widget states.
I learned how to implement authentication mechanisms, maintain the auth tokens locally, auto-login, and auto-logout the users from the application.
