March 2026 monthly summary for flutter/flutter-intellij: - Delivered Flutter Project Open Robustness: Removed the FlutterProjectOpenProcessor to prevent silent failures when opening Flutter projects that lack an .idea directory in IntelliJ IDEA. Implemented post-open initialization in FlutterInitializer to configure Flutter-specific settings after the project is opened, enabling correct handling of Flutter modules. - Key commit: 4681015cd82dfc4b675f7e3471648853238855e3 (Fix IntelliJ IDEA project open hang; remove processor; add module-type fixing and Dart SDK enablement for unconfigured modules). The change includes removal of the projectOpenProcessor, updates to plugin initialization flow, and a changelog entry. - Validation across environments: Verified opening a Flutter project without .idea works in IntelliJ IDEA, while existing projects with .idea continue to open correctly; Android Studio remains unaffected. Flutter 3.8.1 / Dart 3.8.1 compatibility confirmed on macOS. - Collaboration and coverage: Co-authored by Georgii Kostenko; issues addressed include #8845 and #8846; changelog updated to reflect behavior improvements. Overall impact: Significantly reduces project-open failures, improving first-run reliability for Flutter developers and streamlining onboarding across IDEs. Technical achievement demonstrates deep IntelliJ Platform knowledge and Flutter integration, aligning with Android Studio fixes for parity across JetBrains toolchains.
