proposal: `avoid_unused_private_function_parameters`

[stephane-archer]

does it make any sense to have unused function parameters when the function is private in a class?

class foo {
void _bar(int I) {
print("hello word");
}
}

Maybe.

If you override the method in subclasses inside the same library, and the other methods use the parameter.

If you tear off the method and pass it to something expecting a parameter.

Can an optional lint, in that case, could make sense? Not everyone needs to do this and an unused parameters can be hard to spot in your codebase.
