Summary of Issue

Simply adding cloud_firestore to pubspec.yaml results in a huge increase in Flutter macOS XCode build times. The issue can be recreate with nothing more than a simple flutter create application and minor changes to pubspec.yaml.

@TahaTesser Thank you for testing! 😍 I added the result to the ticket description 👍

More than a year and still waiting for some solution. It's very frustrating when you see they give a s* about this issue.

[nilsreichardt]

@cbalmeida Luckily they found a workaround for iOS after more than half a year. Maybe we will have a workaround in 2021 ;)

Some context as to why this doesn't work for macOS: invertase/firestore-ios-sdk-frameworks#11 (comment)

[Salakar]

https://github.com/invertase/firestore-ios-sdk-frameworks is now supported on macOS since Firebase iOS SDK v7.4.0, see #4698 for a detailed example of integrating.

Please try it out and let me know how much it helps, thanks

As Mike has mentioned, you may now use the precompiled iOS version. For (if) any further updates regarding macOs build times, I'd follow #4698.
