flutter-intellij: Exception while activating newly installed flutter plugin.

IntelliJ seems to indicate that we are accessing UI components from a background thread.

Steps to reproduce: I was following installation instructions:

Flutter plugin installation

During alpha development, the Flutter plugin is hosted in its own plugin repository. Before it can be installed, the repository needs to be added to the IDE.

Open plugin preferences (Preferences>Plugins on macOS, File>Settings>Plugins on Linux) Select “Browse repositories…” In the Browse Repositories dialog, click “Manage repositories…” In the resulting Custom Plugin Repositories pop-up, click the + button and paste https://flutter.github.io/flutter-intellij/alpha/updatePlugins.xml into the Repository URL: field and click OK In the Browse Repositories dialog, select flutter-intellij from the list of plugins (be sure it is not being filtered out of your results view by specifying Category: All or limiting it to the Flutter repository in the pull-down by the search box) and click the green Install button Once downloaded, click the Restart IntelliJ IDEA button Flutter plugin configuration

Open preferences (Preferences on macOS, File>Settings on Linux) Select Languages & Frameworks>Flutter Set the path to the root of your flutter repo Click OK

Exception occurred after the final OK click. Happens again after restart of IntelliJ and repetition of the last four steps above.
