The 2021.3 is now the current stable version

christopherfujino · 2021-11-30T22:55:59Z

This appears to be a failure while decoding a zipped file inside dart.jar. action item for myself: we should catch FormatException and then fail the validator, hinting that their editor installation is likely corrupted (or maybe just their extension)

woprandi · 2021-12-02T20:45:14Z

It's strange since the extension seems to work as usual

christopherfujino · 2021-12-02T22:27:29Z

@stevemessick do you have any insight in to why we're failing to decode a zip within dart.jar?

stevemessick · 2021-12-02T22:52:28Z

I don't have any direct knowledge. I'd assume it (the Dart code) needs to unpack the META-INF/plugin.xml file from Dart.jar and look at the tag. Perhaps the file encoding changed in 2021.3? If the Dart plugin works (and it must if Flutter does) then the Dart.jar file itself is probably fine.

@christopherfujino @stevemessick

I just tried to read the same jar files from IntelliJ IDEA 2021.3 stable
Looks like dart.jar cannot be read, while flutter-intellij-63.1.4.jar reads just fine using archive, which is used in intellij.dart.

https://github.com/flutter/flutter/blob/master/packages/flutter_tools/lib/src/intellij/intellij.dart#L5

As you can see archive sample code. just reading Dart.jar throws the error.

Code sample

import 'dart:io';
import 'package:archive/archive.dart';
import 'package:archive/archive_io.dart';

void main() {
  // final Archive archive = ZipDecoder().decodeBytes(File('assets/flutter-intellij-63.1.4.jar').readAsBytesSync());
  final Archive archive = ZipDecoder().decodeBytes(File('assets/Dart.jar').readAsBytesSync());

  // print('intellij plugin: ${archive.files}');
  print('dart plugin: ${archive.files}');
}

  assets:
    - assets/Dart.jar
    - assets/flutter-intellij-63.1.4.jar

@noordawod, you can do as instructed to purge local changes.
Otherwise, "cd" to FLUTTER_HOME and execute "git reset --hard; git clean -fd". Then "flutter doctor -v" will build the flutter tools once again, but will produce the initial error as well.
At this point you are free to do "flutter upgrade", if the error persists, then simply repeat the above "patch".

noordawod · 2022-01-10T08:20:28Z

Well, I know how to "forget" the patch. I was interested more to know how to "keep the patch" while still being able to upgrade Flutter without the need to re-patch.

TahaTesser · 2022-01-10T09:06:51Z

Hi everyone
I can confirm updating archive in tools does solve the issue (thanks @brendan-duncan for fixing the archive issue, details in #96018)
This change should be landed by #96325, thanks for the patience

[✓] IntelliJ IDEA Community Edition (version 2021.3.1)
    • IntelliJ at /Applications/IntelliJ IDEA CE.app
    • Flutter plugin version 63.2.4
    • Dart plugin version 213.5744.122

jmagman · 2022-01-11T02:05:51Z

Fixed by #96325.

danagbemava-nc · 2022-01-17T12:29:08Z

To anyone else who experiences this issue on stable 2.8.1, the fix for this is on the master channel and it should roll out to stable sometime in the future.

Please be patient.

Thank you

johnaaronrose · 2022-01-21T13:53:25Z

I do not understand how to fix this bug. I've tried running 'flutter update-packages --force-upgrade' as sort-of-instructed in #96018. That completes Ok but 'flutter doctor' still gives the same problem. Could someone please put simple instructions on this thread detailing how to fix this bug?

omidshojaee · 2022-01-21T14:01:44Z

Currently the only workaround is to switch to Master channel. I don't recommend that because the code in that channel is not tested. But if you have no choice then run 'flutter channel master' and then run doctor again.

Thanks, omidshojaee. I don't have any choice if I want to install flutter. Do you know when the fix will be deployed on stable? Presumably, I can switch back to stable by running "flutter channel stable" when the fix is deployed to stable: is that correct?

danagbemava-nc · 2022-01-21T14:32:26Z

Hi @johnaaronrose, you should be able to install and use flutter just fine in spite of that error. Is there anything you're running into that is preventing you from installing/using flutter?

omidshojaee · 2022-01-21T14:40:35Z

Roughly every quarter from Beta to Stable, and every month from Master to Beta, according to wiki <https://github.com/flutter/flutter/wiki/Flutter-build-release-channels>. And yes you can switch back to stable whenever you want. Once again, I'm not recommending the master channel. Try VSCode or Android Studio.

I want to use flutter & dart and the instructions (at https://docs.flutter.dev/get-started/install/linux) say to use IntelliJ Idea as well as having Android Studio installed. The flutter installation instructions (at https://docs.flutter.dev/get-started/install/linux) say "fix this problem and then rerun flutter doctor":
[☠] IntelliJ IDEA Community Edition (the doctor check crashed)
✗ Due to an error, the doctor check did not complete. If the error message below is not helpful, please let us
know about this issue at https://github.com/flutter/flutter/issues.
✗ FormatException: Unexpected extension byte (at offset 5)

Also, when I try "flutter channel master", I get a lot of output including:
git: error: Your local changes to the following files would be overwritten by checkout:
git: Please commit your changes or stash them before you switch branches.
git: Aborting
Switching channels failed with error code 1.

I have NO experience of git, so I don't know what to do. Please advise.

jmagman · 2022-01-21T19:34:57Z

As @danagbemava-nc politely said, #96325 is available on the master channel. Which means at some point in the future it will be available in a future beta and stable release. You can follow along with that commit to see what tags are added, which will tell you which release it will be in https://github.com/flutter/flutter/wiki/Where's-my-Commit%3F#finding-the-versions-that-contain-framework-commit-x

See our documentation at https://docs.flutter.dev/development/tools/sdk/upgrading#switching-flutter-channels for how to change to the master channel, if you would like the fix before it reaches stable. update-packages --force-upgrade has absolutely nothing to do with changing channels.

If you continue to see this issue, or are seeing an unrelated issue with changing channels, please file a new GitHub issue.

Locking.

Seeing quite a few instances of this; is it something that we might be able to cherry-pick, @jmagman? If not, then LMK and we can add a temporary note to the install instructions that this version is incompatible.

Let me look into the feasibility of cherry-picking this (pub package cherrypicks are tricky)

Let me look into the feasibility of cherry-picking this (pub package cherrypicks are tricky)

I tried to just update package archive on the stable branch, but I was not able to version solve without pulling in several other transitive updates that also depend on package:archive (source_span, win32, path_provider_*, xdg_directories, possibly others). Thus I would classify this as a high risk cherrypick and would recommend against doing so.
