Is there any way to share the boilerplate across our flutter samples?

What files need review - it's just the lib/ directory right? I wonder if we can find the right config to mark more of these as generated - are there any directories which we know are fully generated and won't be edited by hand?

I started on this in #154

I tried to be conservative in the patterns - these are the ones I'm pretty confident will never be hand edited. Are there any others that we can know ahead of time will never be hand edited or need human review?

This has been landed in flutter/samples:

Should be safe to close this PR now. (I don't have the access level to do so personally.)
