Dart-code: Error: Emulator didn't connect within 60 seconds

[MaisGurbanov]

When I am trying to launch an Android emulator through the VS Code, I am receiving the following error:

"Failed to launch flutter emulator: Error: Emulator didn't connect within 60 seconds".

Below is the output for "flutter doctor -v" command outside of the VS Code:

I can launch an emulator through the terminal by executing the "emulator -avd flutter_emulator" command and it launches successfully. Then VS Code also detects that emulator and displays it in the devices bar at the bottom part.

same here, but for iOS - don't really care for Android.

My error in VSCode Debug Console looks like:
Exception attempting to connect to the VM Service: SocketException: OS Error: Connection refused, errno = 61, address = 127.0.0.1, port = 58050

flutter doctor -v output (outside VSCode):

You may also want to add it to your PATH environment variable.

My emulator works - doesn't matter what device I use (saying this b/c someone mentioned using iPhone SE is relevant b/c it's not new enough?).

I've made sure to:

• [x] add Google-Service.plist by right-clicking Runner and Add Files... in the ios/Runner XCode workspace
• [x] uncommenting platform number 13.0 in Podfile
• [x] running pod repo update
• [x] losing my mind w/ a bunch of other attempts i'll try to remember everything i've tried...

@MaisGurbanov when you launch the emulator from VS Code and get this message, do you see the emulator launch and appear? If so, does it show up in flutter devices once it is loaded? (The output of flutter doctor you posted says no connected devices, but it's not clear if you ran it after launching the emulator). Could you try capturing a log using the Dart: Capture Logs command (you can untick Analysis Server, but leave everything else ticked).

@rasreee this seems like a different problem with a different message, could you file a separate issue and also include a log captured with the above command? Thanks!

You can try to wipe the data of the particular device.

Go to -> Android Studio -> Tools -> AVD Manager -> [Select the down triangle on your chosen device] -> Wipe data.

Now retry.

This one works well for me

It worked for me too, thank you.

This does works but it keeps happening often. Any permanent fix on this?
