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.

  • Does ’flutter create flutter_app4` in a shell work? Commented Mar 6, 2018 at 19:06
  • @GünterZöchbauer Trying it now. How long should it take? If less than a minute then it is not working. :( Commented Mar 6, 2018 at 19:19
  • Ok, so it's not related to the IDE, but only to your Flutter setup. What output does flutter doctor -v produce? Commented Mar 6, 2018 at 19:22
  • So, now flutter doctor is not finishing either. It seems to be in some sort of a loop. I added "echo on" to see. The output is in my update above. Commented Mar 6, 2018 at 20:02
  • I'm not able to make sense from this output. I'd try reinstalling Flutter (no a sophisticated answer, I know) Commented Mar 6, 2018 at 20:09

Had the same issue.

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

it works perfectly but may I know what are the possible reasons. Its not good running android studio each time as administrator
@muhammadobaid Sorry for the really late reply. I haven't been using flutter for a while. Regarding your question, I believe it was because flutter was installed into a restricted storage space (I guess its the C drive here)

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.

Right! As usual It's clear, if the Flutter SDK is located in C:\, Android Studio cannot run flutter, because it requires administrator's grants. So, open it with them and create your project.

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.

In my case this was the issue - I checked create project offline checkbox. Please sure that this checkbox is unchecked.

After selecting options and when "creating new Flutter project" appeared, end Android Studio process and re-run it then - instead of creating a project- choose Open Project and select the project folder that you created before .

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

For me this worked in Windows 10 :

  • Flutter SDK location : kept it under c:\Users<username>\AppData\Local
  • Project location : kept it under c:\Users<username>\AppData\Local
  • Start Android Studio in Administrator mode : this was not required it worked without Administrator privilege
  • While creating the new Flutter project : create project offline choose this option (another answer in this same post which has a screenshot says, do not select it, but for me it worked only after selecting this option)

How much time it took to create the project ? 2 minutes

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.

It might sometimes be as a result of the current version of Flutter and Dart plugins. Check the plugins and update if requested. File >> Settings >> Plugins

The solution which worked for me in windows.

I have placed flutter sdk folder in C:\Program Files.

When android studio try to access the folder, it wont work as admin rights is required for that folder.

  1. Run android studio as administrator and create a new project
  2. Else flutter sdk can be placed in User folder C:\users\username\flutter or other drives which does not require elevated rights.
