Does this happen all the time when you create a new Flutter project?

Yes, this problem happens all the time when creating a new project on idx in the Flutter workspace, and in all projects, and I haven’t been able to solve this problem.

Just to help me debug, can you try in Chrome and let me know if the error still happens?


Even in Chrome, when creating a new Flutter project on idx, the web emulator works but the Android emulator does not. I tried creating other projects, but the same issue persists.

Let me ping our team to look into this in greater detail. Thanks for flagging this.

You’re welcome, and I hope you resolve this issue as soon as possible. Thank you.

We’re looking into why the onCreate hook is not running.

Can you run this command manually in the terminal please to see if the android preview shows up after?

cd /home/user/myapp/android && ./gradlew
–parallel

I had the same problem, Here is a solution that worked for me:

first check if your device is authorized : in the terminal : ‘adb devices’.
it should be authorized, if not, then try to deconnect and reconnect usb device in the settings (developer mode), when the device is authorized, do ‘adb reboot’, then do ‘flutter doctor --android-licenses’, then reboot, then connect to localhost:5555 or any port the output provide… (‘adb connect locahost:5555’)

it should be good, here is the output :
