Flutter-intellij: Android Studio stuck when creating new Flutter project（macOS）

[HLQ-Struggle]

When I use Android Studio on macOS to create a Flutter project, I have been stuck in the prompt box to create a Flutter project here.

The basic information about Flutter on the personal computer is attached below.

When I execute the flutter doctor -v command, it tells me that my local Flutter environment is fine.

But I do n’t know why, creating Flutter using Android Studio will always be stuck creating the Flutter project here.

Could you please tell me how to solve this problem, thank you.

I personally tried to use Google search, but I have not found an effective solution. Looking forward to your reply, thank you.

[HLQ-Struggle]

The following is what I just tested to create a Flutter project through Android Studio. As shown in the figure, I have been stuck in creating a Flutter project.

OMG, why can't the pictures I upload show? How can I provide you with effective content so that you can view the problem intuitively?

[HLQ-Struggle]

Over the wall, global agent.

It may be a way, but I have already configured the domestic when downloading and configuring Flutter. It should be reasonable that it should not be pulled from domestic sources?

Hi @HLQ-Struggle
This is probably due to insufficient disk permission
Can you please make sure you've Full Disk Access for Android Studio enabled in Security & Privacy?
Can you try a creating project using terminal with flutter create demo and let us know if it works?
Thank you

[HLQ-Struggle]

Hello, thanks for your reply, here I explain the operation.

First of all, I was confirming that the local Flutter environment is normal, and also updated to the official version of Flutter, and then created the Flutter project through Android Studio, but found that I have been stuck in Create Flutter Project ... here. By looking at the macOS process, there are multiple darts.

Then began to try to create the Flutter project through the flutter create command, and found that it can be created normally.

I want to ask, what factors might affect Android Studio to create Flutter? I confirm that my operating environment is consistent several times.

Finally, I confirm that macOS has been given the highest permissions for Android Studio, because I am an Android developer.

Thank you for your reply ~

Hi @HLQ-Struggle
Did you setup Configuring Flutter china to use a mirror site](https://flutter.dev/community/china#configuring-flutter-to-use-a-mirror-site) ?
Can you please try reinstall flutter intellij plugin?
Thank you

[HLQ-Struggle]

Hi @TahaTesser ,Thank you very much for your reply.

I confirm that I have installed the official website for configuration and also configured the mirror address in China. The following is the configuration Flutter content address I recorded:

https://juejin.im/post/5eb435e46fb9a0435210a377

Attached here is my local configuration content:

# Flutter
# 配置国内镜像
export PUB_HOSTED_URL=https://pub.flutter-io.cn
export FLUTTER_STORAGE_BASE_URL=https://storage.flutter-io.cn
# 配置本地 Flutter SDK 地址 这里记得修改为本地目录地址
export FLUTTER_HOME=/Users/HLQ/flutter/bin 
export PATH=$PATH:${FLUTTER_HOME}

I tried two computers here, one named HLQ and one named heliquan, with the same content.

[VladyslavBondarenko]

@HLQ-Struggle
is project created when you close Android Studio?
is project created when using cmd flutter create project_name? if no, could you provide flutter create project_name -v?

[HLQ-Struggle]

@VladyslavBondarenko The Flutter project can be created normally through the command line.

[stevemessick]

We're sorry you're having this difficulty.

We've seen problems due to not having configured an http proxy. Could that be it?
https://www.jetbrains.com/help/idea/settings-http-proxy.html

Can you create a project if you set the checkbox labeled "Create project offline"?

The log file might have some clues. The menu Help > Show log in Finder will get you to it. Scan that after trying to create a project and see if the latest entries can help. If you're not sure, append the latest (not the whole big thing) here.

Having multiple Dart processes is not unusual. However, rebooting to clean up everything probably wouldn't hurt.

[HLQ-Struggle]

Hi @stevemessick ,Thank you very much, just try a wave.

I also stuck, and I get a log:

Hi, plz try a VPN, cause when creating a flutter Project, you need to get some kinds of connections to Google Co which were banned by Chinese Gov
Make sure that your VPN is in GLOBAL MODE, not only permit websites or connections in WHITELIST
