Support log to VSCode debug console when using flutter attach #3195

For now, when using VSCode to attach an add-to-app flutter project, the console will be redirect to android studio log console. So every time I debug the project, I need to open android studio and VSCode the same time.

I notice that flutter devtools logging panel can capture the log of the project, and vscode debugger should be able to communicate with devtools. So, I think it should not be hard to implements log just to vscode debug panel?
