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.

Here's my output from the doctor.... Did a consistent solution ever appear? Thank you!

[evalsxonted]

same problem for me, any new solution?

[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.

[elias8]

Delete .dart_tool folder from your project root directory.

[efraespada]

Same issue here when updating to Flutter 2

[efraespada]

I noticed my problem was a local dependency added to my project:

dependencies:
  random_name:
    path: ../random_name

Using the git integration solved my problem.

dependencies:
  random_name:
    git:
      url: https://github.com/efraespada/random_name.git

But it is crazy how a simple dependency can block/break your project indexation.

[AurelienDud]

New day, new flutter bug
Just bumped into this, seemingly caused by a specific widget tree

Not a Flutter bug. I'm also looking for a fix of this problem... but i'm using React-Native (Android files in Java). 😏

[MikePendo]

Same issue Channel stable, 3.3.3 (Android) Android Studio (version 4.1)

[chloeeee72]

Same issue Channel stable，3.3.8

[chloeeee72]

flutter pub get

it works for me!!!! thanks

[AhhhhDong]

the useless 'required' will make bug...

[fuadreza]

I have similar bug. For me it is because i use Records. Strangely bug only appear on the line after the Records line.

But after I change the record into single type, I able to go to any declaration.

Hope this info helps.

[bernaferrari]

Same problem. It gets worse with Records.

[bernaferrari]

This is enough to trigger the problem:

Make a file named bug.dart:

import 'package:flutter/widgets.dart';

Widget totalBuilder(List<(String, String)> none) {
  return Container();
}

Reproducible project:
bug.zip

[HieuNghiemViet]

Does anyone have a solution?

[Arhidev]

same problem for me, I moved my project to another folder, a folder with a nomenclature without an accent
