Android studio - flutter: No Connected Devices

Issue

I have just started with mobile development using flutter, and there is this error when trying to run the default flutter program.

No connected devices found; please connect a device, or see flutter.dev/setup for getting started instructions.

• This is a Windows 10 x64 machine.

• Installed Android Studio in - D:\Program Files\Android\Android Studio1

• Installed Android SDK from Android Studio in - D:\Android\android-sdk

• Set these system environment variables

  ANDROID_HOME - D:\Android\android-sdk;D:\Android\android-sdk\tools;D:\Android\android-sdk\build-tools;D:\Android\android-sdk\platform-tools

  ANDROID_SDK_ROOT - D:\Android\android-sdk;D:\Android\android-sdk\tools;D:\Android\android-sdk\build-tools;D:\Android\android-sdk\platform-tools

• Installed Nexus 6 API 28 device & set Emulated Performance Graphics to Hardware GLES-2.0

• Installed pie Android 9.0 x86 & pie Android 9.0 x86_64 as I was unsure which one to use. The AVD emulator launches fine with both the OS. (Which one to use?)

• Installed flutter in - D:\Flutter\flutter

When I run main.dart, it shows this error:

When I run flutter doctor in the Android Studio it shows 2 issues:

[X] Android toolchain - develop for Android devices
    X ANDROID_HOME = D:/Android/android-sdk
      but Android SDK not found at this location.
[!] Connected device
    ! No devices available

When I try to run a command in powershell from the flutter directory, it gives this error:

Solution

In environment variables > User Variables, add a new PATH, like: C:\src\flutter\bin

Then restart your machine.
