Android Studio indexing every 2 seconds

In Android Studio 3.1 Beta 1 (and 3.2 Canary 1) indexing is triggered every 2 seconds, which makes e.g. code completion tooltips go away. Excerpt from the log (this continues forever):

2018-02-04 12:39:19,749 [e-1024-b01]   INFO - pl.ProjectRootManagerComponent - project roots have changed
2018-02-04 12:39:19,762 [ thread 11]   INFO - .diagnostic.PerformanceWatcher - Pushing properties took 1ms; general responsiveness: ok; EDT responsiveness: ok
2018-02-04 12:39:19,772 [ thread 11]   INFO - .diagnostic.PerformanceWatcher - Indexable file iteration took 10ms; general responsiveness: ok; EDT responsiveness: ok
2018-02-04 12:39:21,760 [e-1024-b01]   INFO - pl.ProjectRootManagerComponent - project roots have changed
2018-02-04 12:39:21,772 [ thread 12]   INFO - .diagnostic.PerformanceWatcher - Pushing properties took 0ms; general responsiveness: ok; EDT responsiveness: ok
2018-02-04 12:39:21,776 [ thread 12]   INFO - .diagnostic.PerformanceWatcher - Indexable file iteration took 4ms; general responsiveness: ok; EDT responsiveness: ok

This also happens when there’s no tab with Flutter/Dart code.

Steps to Reproduce

• Create new Flutter Project (in Android Studio 3.0, because of #1649);
• open main.dart file
• observe indexing

@acidjazz dude instead of waiting for someone else to fix - find a way. Download an older version of Android Studio, do some searching on StackOverflow, follow the instructions above. The longer you wait for someone else to solve your problems the more miserable you will become. Become your own hero.
