Flutter IntelliJ Plugin M40 Release
After following the instructions to add a Flutter module to an Android app you can open the app in Android Studio and the Flutter code will be linked in for full-featured editing. Please be patient when opening the app for the first time; Gradle has to do its thing and then do it again to make everything work right.
This shows an Android app called ModTest that has a Flutter module named sample. The editors show syntax highlighting of both Kotlin and Dart code.
The Build menu has Flutter-specific build actions available when the selected project item is a Flutter item.
The change log has a list of bugs that were fixed in this release.
