IntelliJ IDEA 2025.2 (Ultimate Edition) is not supporting all flutter related plugins like dart, android, flutter etc

It appears that IntelliJ IDEA 2025.2 Ultimate currently does not officially support Flutter‑related plugins like Flutter, Dart, and Android plugins via the JetBrains Marketplace. This is a compatibility problem tied to the new 2025.2 release cycle, not a bug in your configuration.

🔍 What's going on?

• Flutter and Dart plugins declare compatibility ranges (until-build) that exclude newer versions such as 2025.2. Even though they may work fine, IntelliJ blocks installation because the plugin metadata marks them as incompatible (GitHub, JetBrains Platform).
• This exact issue occurred for IntelliJ 2023.3, wherein users had to manually hack the plugin ZIP to bypass the until-build constraint. It worked—but at their own risk because APIs may have changed (GitHub).
• Forum threads on IntelliJ 2025.2 EAP revealed plugin verification failures (“could not extract plugin archive”) due to internal changes in the plugin verifier. The infrastructure has since been fixed but may still cause compatibility noise (JetBrains Platform).

✅ What you can do

Option A: Install manually by editing plugin ZIP

1. Download the Flutter and Dart plugin ZIP files from the JetBrains plugin repository.
2. Open the .zip, go inside META-INF/plugin.xml and remove the until-build attribute or bump it to include 2025.2.
3. Repackage and install via File → Settings → Plugins → Install from Disk….

⚠️ Warning: This may not work with all functionality. Behaviors might break due to changed internal APIs.

Option B: Downgrade IntelliJ to 2025.1 (or lower)

• Use JetBrains Toolbox to revert to 2025.1, which is supported by the official Flutter/Dart versions.
• Plugins should install and function as expected.

Option C: Switch to Android Studio or IntelliJ IDEA Community 2025.2

• Android Studio tends to maintain Flutter support faster than IntelliJ Ultimate.
• Alternatively, note the unified distribution policy: LSP APIs and IntelliJ Ultimate features are now available even without a paid license, but the plugin compatibility issue still applies unless the official plugin metadata is updated (Stack Overflow, JetBrains Platform).

🛠 Tips to get back up and running

• Make sure Flutter SDK, Dart SDK, and Android SDK are correctly installed and their paths configured (flutter config --android-sdk-dir=..., etc.)—they must all be accessible (Reddit).
• If you switch back to Android Studio, run flutter doctor -v to ensure no old installations are referenced accidentally (especially on Windows) (Reddit).
