Add a firebase plugin like firebase_analytics to a vanilla Flutter project and time how long it takes to download the dependencies from a clean environment.

1. flutter create my_app && cd my_app
2. flutter config --enable-swift-package-manager
3. flutter pub add firebase_analytics
4. rm -rf $HOME/Library/Caches/org.swift.swiftpm
5. rm -rf $HOME/Library/org.swift.swiftpm
6. rm -rf $HOME/Library/Developer/Xcode/DerivedData
7. cd ios
8. time xcodebuild -resolvePackageDependencies

The "real" time outputted is usually around 4 minutes

4 minutes to download 1 plugin and it's dependencies is pretty bad

I don't think it's related to my internet connection because I'm getting 120 Mbps down.
