Android Studio stuck when creating new Flutter pro

Question

I have installed Flutter on Windows and checked all is ok using flutter doctor. I imported the Flutter plugin.

Now, when I try to create a new Flutter app via Anroid Studio it never ends. I get "Creating Flutter Project" and that's it.

The message area contains ""C:\Program Files\Flutter\flutter\bin\flutter.bat" --no-color create --template app --description "A new Flutter application." --org anykey.co.il flutter_app4" It seems to be stuck on "Building symbols...".

I even left it on overnight hoping it would finish.

In the end I have to kill it.

Edit: It seems that my flutter.bat file is looping. I tried flutter doctor (who echo set to on) and this is what I get. The last part loops forever.

Answer 1

I was struck with the same problem a while back. After a lot of stumbling I got it right. First of all delete your previous cloned flutter files and install git in your user folder. Like C:\users\username\

Clone flutter in your git directory,set the path C:\users\username\git\flutter\bin

Now use the command flutter doctor If you have android studio and intellij IDE, install flutter plugins in both of them and now create a new project.

You are all set to go

Answer 2

I have disabled the Antivirus(Quick Heal), and run the CMD as administrator and run "flutter" command. It's working. Then checked the "flutter doctor" command, It's also working fine.

Then started the AS as administrator mode and create the flutter app and it's started working now.

Answer 3

This is likely because you've put Flutter in Program Files which requires admin permissions to be able to write its cache files.

I've got a PR Open that should result in a more friendly error, but I'd recommend moving Flutter away to a folder that non-Admin users can write to.

Answer 4

For windows 10 there is couple of solution here, I am sharing with here which is working for me.

1. Set Flutter SDK path is present in AS Settings . Settings > Languages & Settings > Flutter > Flutter SDK Path

2. Run Android Studio/IntelliJ in administrator mode

3. Your project location path folder name is valid Dart package name.

Answer 5

I had the same issue on MacOS 10.13.4, when creating a new Flutter project on the Android Studio (3.1), the IDE got stuck, showing the phrase "building symbols" on the bottom of the window.

When running the command flutter run on the cli, the message was: startup lock.

then I removed the lock from the flutter sdk cache: rm ./bin/cache/lockfile

this is an issue reported on https://github.com/flutter/flutter/issues/7768

Answer 6

Had the same issue.

Just run Android Studio/IntelliJ in administrator mode. It works.
