Got a 'NullPointerException' from the IDE when running a main.dart file in a new flutter project #7723

Closed JohnH07 closed 1 week ago

JohnH07 commented 1 month ago

What happened

I ran a main.dart file on my Android Emulator and I got an IDE error pop up saying an error has occurred and prompted me to make a new issue with the bug report. This has happened before and seems to happen when I run a main.dart file for the first time in a new flutter project. After closing out of the pop up everything seems to work fine.

Batch close for the com.intellij.openapi.wm.ToolWindow.setAvailable(boolean) exception out of the Flutter IJ plugin, this is a duplicate of https://github.com/flutter/flutter-intellij/issues/7691 and is resolved in the release of the Flutter plugin, 82.1.
