Connecting to an external flutter app

[FlafyDev]

When running a debug/profile flutter app executable, you get flutter: The Dart VM service is listening on http://127.0.0.1:12345/. You can connect to it in vscode or by typing flutter attach --debug-uri=http://127.0.0.1:12345/. This will allow you to open devtools and control the app(like doing hot reloads). It will be nice if this plugin will be able to attach to a debug uri.

I need this feature for debugging a flutter app. The app uses flutter's embedder API, so it cannot be opened directly from flutter run.
