title: How can I add a break point in VSCode to a dart file from an imported package?
body: <p>When an exception is thrown from within a dart file from an imported package VSCode will automatically open that source file to show where the exception was thrown. Once this file is open and attached to the debugger I appear to be able to add break points anywhere inside. This makes me believe it should be possible to add other files manually. I would like to open and attach other dart files to the debugger that I know are being referenced and add break points.</p>
