No connected devices found; please connect a device

问题

I just open my flutter project in android studio but android studio cannot detect any device. I already installed two emulator from AVD manager but still I face with this error

Mostly this happens when your Android SDK path is not configured. To do this you can do it as follow:

1. First of all make sure make sure you followed the installation process

2. Go to File -> Project Structure select Project from left tab and select <No SDK>

3. Then from the devices list click on one of the AVDs to run
4. Make sure your build gradle correctly done
5. Run flutter doctor to check if devices are connected
6. Run your project
