### Background

Flutter generates a `Package.swift` file that contains the plugins that
should be built using SwiftPM.

Since Flutter does not support Swift Package Manager in add-to-app
scenarios yet, Flutter uses CocoaPods to build plugins if you call
`flutter build ios-framework`. To ensure `pod install` is rerun, the
tool deleted the `Package.swift` file.

Unfortunately, deleting the `Package.swift` file causes the Xcode
project to no longer build if it has SwiftPM integration. This caused
the [`build_ios_framework_module_test` to fail when SwiftPM was turned
on by
default](https://ci.chromium.org/ui/p/flutter/builders/prod/Mac%20build_ios_framework_module_test/21807/overview).

### Fix

Instead of deleting the `Package.swift` file, we instead generate a
`Package.swift` file with no dependencies. This will invalidate the
fingerprint and cause `pod install` to rerun if the app had plugins that
were previously built using SwiftPM.
