Just a quick reminder that it is now possible to develop Flutter apps on Windows, too. The setup consists of a couple of easy steps and is well documented here. If you have already installed Android Studio, it boils down to:
Cloning the Flutter repo
Setting the PATH environment variable
Running flutter doctor
Picking your favorite editor and installing a Flutter plugin
I prefer IntelliJ, which offers a seamless integration of Flutter. Below is the screenshot of my sample Flutter app called Temperature Converter.
Please keep in mind, that you cannot build iOS apps on a Windows machine.
