Flutter Run & Debug not showing simulator/device list

Deva_obeth · March 19, 2026, 6:10am

Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

I’m facing an issue in Cursor IDE where Flutter’s Run & Debug panel is not showing any available simulators or devices.

Environment:

OS: macOS (Intel)

Flutter version: (please fill: flutter --version)

Dart version: (please fill)

Cursor version: (please fill)

Xcode version: (if using iOS, please fill)

Issue Details:

When I open the Run & Debug panel, the device selector is empty.

No iOS simulator or Android emulator is listed.

The “Run” button is visible, but no target device is available.

Flutter project is correctly detected.

What I Tried:

Ran flutter doctor → no major issues

Restarted Cursor IDE

Restarted simulators/emulators

Verified Xcode & Android Studio setup

Ran flutter devices in terminal → devices are listed correctly

Reinstalled Flutter SDK (optional if you did)

Expected Behavior:
Cursor should detect and list available simulators/devices (same as VS Code does).

Actual Behavior:
No devices are shown in Run & Debug panel.

Does this stop you from using Cursor

Yes - Cursor is unusable

Hey, this is most likely a Flutter or Dart extension issue rather than Cursor itself. Device detection is handled entirely by that extension, and Cursor uses the standard VS Code debug infrastructure here.

A few checks to narrow it down:

Open View > Output, switch to the Flutter and Dart channels, and look for any errors there.
Verify dart.flutterSdkPath is set correctly in Settings with the full path to your Flutter SDK.
Try Cmd+Shift+P > Flutter: Select Device and see if devices show up there.
Try rolling back the Flutter and Dart extensions to earlier versions. Click the gear icon on each extension, then Install Another Version. A similar issue was resolved this way: Flutter debug always disconnect in version 0.40.4

Also, please share:

flutter doctor -v output
flutter devices output
adb devices output if you’re using an Android emulator
Installed Flutter and Dart extension versions in Cursor

One more thing. Your description says macOS Intel, but system info shows Darwin arm64. Can you confirm which one it actually is?

With those details, it should be straightforward to pinpoint the cause.

Run “flutter emulators” to list and start any available device
emulators.

If you expected another device to be detected, please run
“flutter doctor” to diagnose potential issues. You may also try
increasing the time to wait for connected devices with the
“–device-timeout” flag. Visit Install Flutter for
troubleshooting tips.

Flutter SDK and your devices are definitely fine, flutter doctor is clean, and all 4 devices show up. That confirms the issue is specifically with the Flutter or Dart extension inside Cursor.

A few things left from my last message:

What versions of the Flutter and Dart extensions are installed? Extensions panel > Flutter/Dart > the version next to the name
What do you see in Cmd+Shift+P > Flutter: Select Device, do you get a device list?
Any errors in View > Output > Flutter or Dart channels?

If Flutter: Select Device is also empty, try rolling back both extensions to older versions gear icon on the extension > Install Another Version. This fixed a similar issue for other users.
