flutter-intellij: Code Completion not working properly anymore after upgrading to 2021.3

Hi,

I am not quite sure whether this is a Flutter or an Android Studio issue. Hopefully somebody can help me here, when it is a

I upgraded my Android Studio from 4.x to 2021.3 at the same time I upgraded from Flutter 2.x to 3.3.9) a few weeks ago. From that point my auto completion has not been working properly anymore.

[CTRL] + [SPACE] still opens and display a suggestion list containing
- Flutter internal classes (I assume this is because of already imported flutter/material.dart package)
- Classes from current file
- Classes from explicitly imported files

Everything, which is not already explicitly imported into the current working file is ignored. So I am not able to use automatical imports, I need to find the correct file path by myself and have to include it manually before further writing.

What works:

I observed, an older version of my project works fine on the same setting. So I am wondering, whether a project may becomes too huge? (currently > 1000 files in the lib directory and > 40 external libs in pubspec.yaml) But why did the setup before the upgrade worked properly?
When I open the project on a pure IntelliJ (with installed Flutter/Dart plugins, of course), the code completion works as well

What I tried:

Cleared/Removed every possible cache directory I could find (Flutter, Pub, Android Studio, Gradle, …)
Completely upgraded, removed and reinstalled the entire setup
No PowerSafe mode
My mates have no problems with the project having similar setups

[analyzer] Speedup some completion queries When getting completions, some of the "contributers" basically do a walk of the AST and almost add everything they see, and the list is then later pruned ba... — committed to dart-lang/sdk by jensjoha a year ago

My status so far:

On a test query - asking for completion after the m in an added line print(Cryptm); in the main method in lib/main.dart - I experience the same as you.

I’ve modified the analyzer to have a much larger timeout and then I start getting the wanted results. On subsequent calls (it has to do some stuff the first time) it takes ~400 ms. Most of this time is spent sending log data to the plugin that seemingly does not use it. I’ve created https://github.com/flutter/flutter-intellij/issues/6574 to hopefully get that disabled. For my testing, disabling the flutter intellij plugin so that I only have the dart intellij plugin enabled (which doesn’t ask for the same log data) the query is now answered in ~150 ms instead.

The default timeout is 100 ms so this is still not fast enough, though I would argue for increasing the timeout. I’ve created https://github.com/dart-lang/sdk/issues/51065 for that.

I have another thread to pull to see if I can make it faster and we’ll see what happens.

I completely forgot to make an update on this. I landed https://github.com/dart-lang/sdk/commit/e4f08827095c1352ae35206a6a253b034a9b4b27 which at least on some queries helps quite a bit (taking the query I was primarily testing on from an average of ~155 ms to an average of ~65 ms on my machine — all tested with the dart plugin, not the flutter plugin, but I suppose it should be the same with the new version of the flutter plugin).

I don’t know when there will be a Dart release with it included though.

jensjoha on Feb 2, 2023

Thanks for checking. We have a new plugin ready for release Wed. (I’m doing som final testing today.) That should help with completions, but @jensjoha has already made some improvements to the analyzer that help even more. However, I don’t know when that will be available in Flutter. After version 72 is available, could you update and check again?

I tested it. The autocompletion never appears, not even after 10 tries atm.

S-Man42 on Jan 31, 2023

I gave it several tries, don’t know if it were 6, but surely several times. I can try next week.

I have a similar issue with compiler bugs: I use it as work around for the missing auto complete. To get the import, I use the “resolve issue” feature. It usually takes 3 or 4 tries until the “solve by import package…” point appears. I don’t know whether both issues have relate but maybe this information helps before next week
