Thanks for your hint how to change the template. I also find it boring to delete all these comment lines.
Just now I wanted to switch to channel master to try an example of flutter for desktop. This didn’t work because of the changed template:
git: error: Your local changes to the following files would be overwritten by checkout:

```

git: error: Your local changes to the following files would be overwritten by checkout:
git: packages/flutter_tools/templates/app/lib/main.dart.tmpl
git: Please commit your changes or stash them before you switch branches.

```
It’s no problem. I stash now the changed template. So I can get it back easy after switching channels.
