I did an android studio update and updated flutter and now the IDE is stuck in an indexing loop. At the bottom center it keeps flashing 'Updating Indexes...' and my projects projectName.iml file keeps flashing between being a file icon and a folder with a green dot icon. Also each file error indicator flashes between the green check to the eye icon.

Not Indexing State Icon: Folder Icon
Indexing State Icon: File Icon

I've invalidated the caches and restarted several times and every flutter project is having this same issue. When the update completed I got a flutter notification that reads:

Flutter module type updated
Converted from 'WEB_MODULE' to 'JAVA_MODULE'

Flutter module type updated

I'm able to continue work on the project and launch the application in the emulator without any problems, it's just distracting having this constant flashing on the screen. Anyone else having this problem and found a solution?

Solution 1: Günter Zöchbauer

This is a known issue.


Plugin version 23 was supposed to fix that, but it seems it hasn't.

Solution 2: SeaFuzz

I was able to address this problem by adding

<option name="ALLOW_USER_CONFIGURATION" value="false" />

to my project_android.iml file. Once adding this line, the reindexing loop stopped and it has not even after several days of working and restarting Android Studio. Found the solution in a comment by stevemessick here https://github.com/flutter/flutter-intellij/issues/1735 as per Günter Zöchbauer link reference in the response above.

Solution 3: DDM

I found this comment in an android studio bug and it fixed it for me:

"File -> invalidating caches and restart"

Solution 4: Lestat

Neither invalidate cache nor downgrading Android Studio to 3.1 from 3.1.4 worked (and the "ALLOW_USER_CONFIGURATION" line was already on the IML). I fixed the error by deleting the project and re-cloning / reloading it again on Android Studio.

Solution 5: Iman

in my case, adding

<option name="ALLOW_USER_CONFIGURATION" value="false" />

didn't solve the problem, I also noticed this loop happens just with activities linked to a layout XML file!
