For the time being, we have to run pub run build_runner watch (or flutter packages pub run build_runner watch for Flutter) each time we are working on a project with code generation.

It would be great if this command could be launched automatically if there was a dev dependency to build_runner in the pubspec.yaml file.
This feature should be enabled with a setting, in order to let people decide if want to activate it or not.

What do you think about this?
