Flutter-intellij: IntelliJ IDEA stuck on "Creating Flutter Project"

[tochanenko]

Steps to Reproduce

1. Open IntelliJ IDEA
2. Goto File->New Project and select Flutter (SDK path is correct)
3. Click on Next and Finish

Then it starts looping. It has been doing something for about one hour.

Can you check your IntelliJ log file to see if there are any exceptions (likely near the end)? Or, any suspicious entries?

You could also try enabling the 'verbose' option in the Flutter preference page (Preferences > Languages and Frameworks > Flutter), then re-run the project create step and again check the log.

Does project creation work on the cli? flutter create foo_bar

@devoncarew
That is quite interesting

Creating project foo_bar...
 Writing files
Wrote 66 files.

Running "flutter packages get" in foo_bar...
Failed to rename directory because access was denied.
This may be caused by a virus scanner or having a file
in the directory open in another application.
pub get failed (1)

So I tried disabling Kaspersky and that changed a lot

Creating project foo_bar_2...
// Writing files
Wrote 66 files.
Running "flutter packages get" in foo_bar_2...       14,2s

[√] Flutter is fully installed. (on Microsoft Windows [Version 10.0.16299.248], locale ru-RU, channel beta)
[√] Android toolchain - develop for Android devices is fully installed. (Android SDK 23.0.3)
[√] Android Studio is fully installed. (version 3.0)
[√] IntelliJ IDEA Community Edition is fully installed. (version 2017.3)
[!] Connected devices is partially installed; more components are available.

Run "flutter doctor" for information about installing additional components.

All done! In order to run your application, type:

  $ cd foo_bar_2
  $ flutter run

Your main program file is lib/main.dart in the foo_bar_2 directory.

But creating projects via IntelliJ IDEA is still endless. I looked into log and I found these lines quite strange:

[  17525]   INFO -       ScriptTemplatesProviders - [kts] loading script definitions [] using cp:  
[  17528]   INFO -       ScriptTemplatesProviders - Templates provider KotlinCompilerScriptTemplatesSettings is invalid:

And then it says:

UPD. I checked 'verbose' in Preferences and now it says "Flutter create command was unsuccessfull"
Then I run 'flutter doctor' and it says that everything is OK

I hope this information will be helpfull

I'm not a Windows user and this may be totally irrelevant. Having Flutter installed in

C:\Windows\System32\flutter

seems incorrect and could lead to problems.

See Get Started: Install on Windows.

Running "flutter packages get" in foo_bar...
Connection terminated during handshake
pub get failed (69)

I think firewall is restricting access to some paths.
Do you know for which urls this exception should be added at firewall?

[handstandsam]

I finally got around this. You can diagnose via creating a new project via the command line, and then running an update packages to diagnose proxy issues. NOTE: I had to set a system wide proxy to make this work.

1) Create a flutter project: flutter create foo_bar

2) Run get packages: flutter packages get -v

I found out here that my proxy information was bad. I added an the following to my ~/.bash_profile, closed the terminal and Android Studio, and then reopened both.
http_proxy="http://user:[email protected]:8080"

[madarinho]

Try to "Run as administrator" your IDE.
It worked for me on Android Studio.

I have the same issue when creating a new Flutter project while at work, where the network has a man-in-the-middle firewall. Something is being blocked, but instead of failing gracefully, IntelliJ is hanging indefinitely.

[MishraUdit]

I had the same issue also. When I connected my system to the internet, it completed the task in a few seconds...
I don't know what's the issue behind it, but I think it requires proper bandwidth while creating new projects.
Might be, it is downloading a few files or authenticating any file each time creating new projects.

[nabinbhandari]

I also had the same issue, In my case, I think, it was caused because the process 'dart' was already running in the background. In Linux terminal, I entered killall dart to kill the process and then I was able to create a new project.

[darylrue]

Using my work computer on my home network I'm now having the same issue. If I run
flutter create test_project
it hangs here:
Running "flutter packages get" in test_project...
If I go to an existing flutter project and run
flutter packages get -v
it hangs here:
[C:\Users\path_to_project\] c:\flutter\bin\cache\dart-sdk\bin\pub.bat --verbosity=warning --verbose get --no-precompile

i have the same problem. how did you solve?

[skyh24]

it's so wired. i can use flutter create command to generate new project. But i cannot create flutter project in android studio and it stuck

[DoktorDaveJoos]

This can happen while working behind a corporate proxy.

If you want to create a project with the flutter cli, configure a cntlm - it is necessary that flutter has access/permission to the internet.

If it works on the cli but NOT in android studio or intellij IDEA -> go to file -> settings -> system settings -> HTTP proxy. Configure the proxy manually and !IMPORTANT! check the box "remember" your credentials. After that restart intellij or android studio.

Cheers

Close the http proxy set on android studio solved my problem on mac.
Give myself a thumbup!
