Ignore implicit_dynamic_parameter in generated code

[MisterJimson]

Done and looking for feedback on

• Resolved Generate code that supports implicit-dynamic: false #557 by ignoring specific warning in json_serializable generated code
• Updated example generated code
• Added implicit-dynamic: false to example to demo, let me know if this should be removed

Need advisement

• Updating tests. I have fixed 1 test out of ~40 that fail because the expected output is no longer correct. I'm happy to update them (see the one I updated), but I am wondering if we would prefer to do a contains check instead of an exact match check (which would make all these tests pass without having to update the expected outputs). Or if the inner test code should strip out the warning before comparing. May want to consider future lints we need to disable (NNDB as one example, other Strong Mode stuff, etc)

I want to approve this, but we are really blocked on dart-lang/source_gen#370

This would also handle having to add all of the bits to each generator

Please 👍 dart-lang/source_gen#370

Put this in json_serializable_generator and make it private!

Done

I don’t see it as a blocker. The ignore comment only gets added once in the file no matter how many classes you annotate in the file.

That issue would improve the implementation, but tons of libraries add ignore_for_file to generated output as is.
