Android studio: freezing color scheme and main editor functions when updating lib files

[ArZargaryan]

Steps to Reproduce

just updating project lib file.
Here is the link to the video where you can see the problem.
When it happens, autocomplete doesn't work either.

About problem

In recent times android studio main functions doesn't work for a few seconds very often when updating any project file.
This is very annoying because you have to wait a few seconds(about 5) for the autocomplete to work, or to go to the resource.
This happens when i edit and save any lib file.
I thought my PC is weak and the problem is my PC, so i decided to build a new PC, but it turned out that this was not the problem.

My PC specs:
CPU- AMD Ryzen 7 5800x 8-cores 16-threads 3.8Ghz
GPU - Nvidia Geforce GTX 1650 DDR6 128bit 4gb
RAM - HyperX DDR4 3200Ghz 16gb * 2
Storage - Netac nv7000 (nvme 7gb/s) 1TB

I built this PC 2 weeks ago(all components are new).
I attached a screenshot where you can see that the color scheme is incorrect and when it looks like this, the most important functions that can be performed with the assistance of the editor become non-working

I want to note that the webstorm always works without such friezes.
Intellij IDEA freezes as well.
So i'm sure the problem is in the flutter plugin.
I also contacted android studio support, but they said that similar problems are related to the flutter plugin.

I have the same problem

[ArZargaryan]

I have the same problem

It's so annoying.
Did you fix that?

[stevemessick]

Does this problem occur when the Flutter app is not running?

Would it be possible for you to try older versions of the Flutter SDK to see if this problem was introduced recently? I'm asking about the Flutter SDK, not the plugin, because I suspect this is a performance issue in the Dart analyzer.

[stevemessick]

More specifically, does this problem occur with Flutter SDK 3.3.2 or 3.3.1? Those have earlier versions of the Dart SDK.

As you said i tried flutter 3.3.1 but it still freezes.
I used to have version 3.0.x and 2.8.x but this problem was also then (although on the last PC)

[stevemessick]

Thanks for the info.

[stevemessick]

This is a performance issue in the Dart analyzer. Please create a new issue here: https://github.com/dart-lang/sdk/issues

If you add a link to the issue you create then I'll add the proper labels to bring it to the attention of the analyzer team.

Thank you for creating an issue in dart-lang repo.
I guess I don't need to create an issue anymore?.

[stevemessick]

No, but you could up-vote the one I made.

[srawlins]

@ArZargaryan thanks for filing an issue! Can you indicate whether you have any analyzer plugins in play? These would likely be in analysis_options.yaml for one or more packages in your project. Examples include "Flutter Enhancement Suite plugin" and "Dart Code Metrics".

# check for errors, warnings, and lints.

# The issues identified by the analyzer are surfaced in the UI of Dart-enabled
# IDEs (https://dart.dev/tools#ides-and-editors). The analyzer can also be
# invoked from the command line by running `flutter analyze`.

# The following line activates a set of recommended lints for Flutter apps,
# packages, and plugins designed to encourage good coding practices.
include: package:flutter_lints/flutter.yaml

linter:
  # The lint rules applied to this project can be customized in the
  # section below to disable rules from the `package:flutter_lints/flutter.yaml`
  # included above or to enable additional rules. A list of all available lints
  # and their documentation is published at
  # https://dart-lang.github.io/linter/lints/index.html.
  #
  # Instead of disabling a lint rule for the entire project in the
  # section below, it can also be suppressed for a single line of code
  # or a specific dart file by using the `// ignore: name_of_lint` and
  # `// ignore_for_file: name_of_lint` syntax on the line or in the file
  # producing the lint.
  rules:
    # avoid_print: false  # Uncomment to disable the `avoid_print` rule
    # prefer_single_quotes: true  # Uncomment to enable the `prefer_single_quotes` rule

I consider these are related issues.

No, it`s not a perfomance issue in the Dart analyzer. It's some kind of internal lock in the IDE.

It's still happenning on my side and everthing is updated

The same here

[srawlins]

Please see #3255 (comment). This syntax highlighting issue should be tracked at https://youtrack.jetbrains.com/issue/WEB-56916 and may be fixed by changing line ending encoding.

[mariusvn]

for anyone having the problem, change your line ending from CRLF to LF (unix style).
