Flutter Connected device (the doctor check crashed)

Question

I have installed flutter without android studio. I run it on windows 8.1. All runs well but I had one type of error that keeps saying Connected device (the doctor check crashed). After that, I can't launch the emulator too.

Here is the error I got when run flutter doctor. Anyway, I also tried to enable and disable the hyper-v, too, but it still didn't work and there is no windows hypervisor platform.

How can I solve this issue?

Although compiled Flutter apps run from Windows 7 and above the minimum system requirements for the development environment is Windows 10 or later. Developing on a machine without the minimum system requirements met could give you some undesired behaviors.

Anyway, the problem is that Android Studio is not installed. You need to install it and also the Android SDK Command-line Tools from Android Studios' preferences. Just go Preferences -> Appearance & Behavior -> System Settings -> Android SDK -> SDK Tools tab and select the Android SDK Command-line Tools to be installed like the screenshot below.
