Describe the bug
When starting a Flutter app for the web (either with Chrome or Edge), Dart-Code continuously displays "Compiling lib\main.dart for the Web..." and this message doesn't go away even after a few minutes after the app is running in Chrome/Edge.
Also, and this is probably related, I can not start the Dart DevTools because when I click the corresponding button in the status bar, I get this message instead: "This debug session is not ready yet."
Expected behavior
"Compiling lib\main.dart for the Web..." message disappears when the app finished compiling and is launched.
And be able to start DevTools.
