There was a problem hiding this comment.
We actually do need the file here as we perform some logic below to figure out the package to use.
There was a problem hiding this comment.
I think I had commented not about the passing of file, but the passing of it by reference so it can't be nullptr.

@thomasvl I updated all logic! Let me know if there is anything else for me to change or address! |

Hey @thomasvl in the previous PR we introduced the
default_objc_class_prefixobjc_opt.However, upon using it it had a major flaw. We have protos that we generate this prefix for for namespacing and it is not always the same. Upon using this, we realized that objc class prefix passed was also used when generating code for dependencies which was causing compilation issues. In other words, it was applied globally. This might be OK if anyone decides to use the same prefix for all protos so maybe we can keep that option as well?
I figured anyone can generate a map with the same prefix across all proto files if they desire to do so.
This is basically a different solution to #9469
