Most of you know me for my consistency, a golden arrow in my blog series. I've written 1000 articles in 1008 days! Almost an article a day, and my honeymoon was the only holiday I ever took. I'm super proud of this achievement; it has been a fantasti...

It's not the first time I'll be talking about community. I think it's an essential aspect of any successful tool. This shows in my previous explorations of Astro, Medusa, and now Vendure as well. All these products thrive in a super open, welcoming, ...

The cool part about Vendure is how easy it is to set up and how abstract each layer is. Basically, we get the following elements: External database Server Worker Admin UI Frontend While this is amazing, it also brings a bit of complexity when it co...

The previous article looked at customizing Vendure on a data and process level. In this article, we'll look at customizing emails, as they are often a big part of a webshop system. We'll be looking at two different layers of customization for customi...

Even though Vendure is a pretty significant project out of the box, in some cases, we might want to go in and modify some elements to work to our specific use case. In this article, I'll take a high-level look at some elements we can customize within...

Coming from Ionic, it's pretty straightforward to generate app icons for your app. While doing some research, I learned it's easy for Flutter as well!
Today we'll learn how to automatically generate App Icons for iOS and Android-based on one image source!
The idea is that apps need many different sizes of App Icons for all kinds of devices and resolutions. Yet, we don't want to make all these images ourselves.
Flutter is built in a way we can easily add plugins.
For this one, head over to your pubspec.yml file and add the following line to your dev_dependencies.
dev_dependencies:
flutter_launcher_icons: '^0.8.0'
Then we need to install this plugin by running:
flutter pub get
For our base icon to work, I would suggest having a logo that is 1024x1024px in size. Also, don't use alpha or transparency in this image (for iOS). For Android, you can use transparency.
However, for this demo, I'll use one generic image.
Place this image in a folder called images at the root of your directory.
I made this basic image for my app icon just to demo how it will look.

Head back over to the pubspec.yml file and add the following configuration.
flutter_icons:
android: true
ios: true
image_path: 'images/icon.png'
We could also specify a specific image for iOS or Android:
flutter_icons:
image_path_ios: 'images/icon-ios.png'
image_path_android: 'images/icon-android.png'
To generate the icons, we can run the following command.
flutter pub run flutter_launcher_icons:main
Now when we run the application on our simulator, we should see the app icon we defined. I also opened up the Xcode assets to showcase all the different sizes that have been created.
