Flutter plugin 0.5.2 fails to start SonarQube DCE 2025.1

[patrickpeck]

Dear team,

I am currently working on an upgrade of our SonarQube DCE instance from version 9.9 LTA to 2025.1 LTA.
We are using the flutter plugin 0.5.2. In SonarQube DCE 9.9 LTA the plugins works fine, but it prevents SonarQube 2025.1 from starting up, with the following error message:

Same problem here.

As of SonarQube 10.9 LTS (or in other words - 2025.01 LTA), there is supports by default for Dart/Flutter.
Source:
https://docs.sonarsource.com/sonarqube-server/latest/server-upgrade-and-maintenance/release-notes-and-notices/lta-to-lta-release-notes/#languages

Dart/Flutter (10.6 - 10.8)

Analysis of [Dart/Flutter](https://docs.sonarsource.com/sonarqube-server/latest/analyzing-source-code/languages/dart/) apps is now available. 115 Dart rules were introduced.

EDIT: This is only valid for non-community editions.
Community edition (also now known as Community Build) does NOT support Dart/Flutter. Only from Developer onwards:

Meaning, we would still need this plugin maintained.

Hi team!
Thank you for your work so far, it's very valuable!

We're using SonarQube 10.5.1 Community Edition at the moment and the plugin is working fine, but my users are complaining because of the message appearing on the top of the page : "You’re running a version of SonarQube that is no longer active. Please upgrade to an active version immediately.".

We planned to update to v2025 LTA but this issue prevent us to do so.

Please help! @zippy1978

This issue is stale because it has been open for 90 days with no activity.

We had the same issue, I've created a pull request to make the plugin compatible with Sonar Community 25.3: #254

If you need the updated plugin, I've released it on my fork: https://github.com/AdrienAudouard/sonar-flutter/releases/tag/v0.5.3
