title: the Dart compiler exited unexpectedly
body: <p>I was debugging my project. After some execution, it started showing an error saying that the Dart compiler exited unexpectedly (see screenshot below). I also updated my dart SDK, but nothing happened. I did search on Google, but found nothing that helped.</p>
