emmm... I think I solve it.

• 1.close your project
• 2.delete .idea folder and *.iml files in root path
• 3.open your project

and then i found the *.iml not generated again.

[StarJiao]

@aolose have you solved this problem? I do that as you describe , just can not open my project as a normal flutter project.

[baoxiehao]

emmm... I think I solve it.

• 1.close your project
• 2.delete .idea folder and *.iml files in root path
• 3.open your project

and then i found the *.iml not generated again.

It's not working for me. And the strange thing is other flutter projects are unaffected for now.

[Diaglyonok]

not solved issue, reopen please

[devoncarew]

For people seeing this issue, I would:

• ensure that a flutter sdk is configured in the settings, Language & Frameworks > Flutter page
• try the File > Invalidate caches menu item

@Diaglyonok: does @devoncarew's suggestion work for you?

[Diaglyonok]

@Diaglyonok: does @devoncarew's suggestion work for you?

No, this is not helps, I found only one solution - recreating the project, but after adding some dependency to pubspec.yaml it repeats again.

[Diaglyonok]

Seems that one of the following actions (or their combination) solves the problem:
1) having a good git ignore call git clean -xffd
My gitignore: https://gist.github.com/Diaglyonok/64adccaf923dc6c7522cab1e89a2fe15
2) switching flutter channel to any other and back.
Commands example (if current channel is stable):
flutter channel dev
flutter pub get
flutter channel stable

after any of these actions:
flutter pub get
flutter clean
flutter run ...

Since this problem does not always appear, at the moment I cannot test these solutions again, if you have such a problem, try this solution and report the result, please.

[Diaglyonok]

solution, that i suggested above (first) just tested and it worked for me again.

[evalsxonted]

stopping Onedrive autosync solved the problem for me , i dont know why, how, or what's going on

[vanlooverenkoen]

I am still having this problem with 1.17.4

[hacker1024]

I had this issue, but removing the root project .iml fixed it.

Delete .dart_tool folder from your project root directory.
