This week in Flutter #8

Ever since I first watched this video from the Inkdrop developer Takuya Matsuyama, I wanted to try vim for Flutter. Robert Brunhage published a video on the topic, but I still have to find the right motivation (and time) to give it a try. If you have suggestions, comments, or even if you think I should not do it, please let me know.

Flutter Package Preview: shared_preferences

Carl Wills is back with another introductory article to well-known Flutter packages. This time its shared_preferences.


Flutter GetX Example – Category Selection

Bart van Wezel is also back in this newsletter with an article about how to get started with GetX. There are so many state management packages for Flutter, I suggest you pick one and use that in all your projects. But it is good to know what's available out there, in case you find a package that works better for you.

A new article by the raywenderlich.com team, about Dart, updated to the recent sound null safety feature.


Flutter Drag and Drop – State Management

Bart van Wezel is back (again) with an article about integrating drag and drop with Riverpod. There is a lot of code in this tutorial, and also a common questions section at the end.


Dependency Injection with Flutter

Dependency injection is a well-known technique to achieve separation of concerns, make your code reusable, and testable. In Dart/Flutter you can apply it by architecting your code around it from the start (my preferred way), or you can use catalyst for Dart and flutter_catalyst for Flutter. Julian Finkler, the developer behind those packages, created a new package to make the process of using them easier. From the repository of catalyst_builder:

Catalyst Builder is a dependency injection provider builder for both, Dart and Flutter. It's easy to use and dependency injection is almost done automatically. You only have to decorate your services with @Service and the build_runner will create a service provider for you.

Loading Cloud Storage Images in a Flutter Web App

Recently we adapted a Flutter mobile app we built for a client to the web. The app uses Firebase to host many images. In the mobile version, we cache the images in a folder on the device, using path_provider, but on the web, this is not possible. My colleague Toine Heuvelmans explains in this article how we used hive and CORS configurations to achieve image caching on the web.
