fatalError

Swift Package Manager is currently an experimental feature, please file a bug at
https://github.com/flutter/flutter/issues/new?template=01_activation.yml
Consider including a copy of the following files in your bug report:
ios/Runner.xcodeproj/project.pbxproj
ios/Runner.xcodeproj/xcshareddata/xcschemes/Runner.xcscheme (or the scheme for the flavor used)

To add Swift Package Manager integration manually, please use the following instructions:
https://docs.flutter.dev/to/add-swift-package-manager-manually

Alternatively, to avoid this failure, disable Flutter Swift Package Manager integration for the project
by adding the following in the project's pubspec.yaml under the "flutter" section:
config:
enable-swift-package-manager: false
Or disable Flutter Swift Package Manager integration globally with the
following command:
"flutter config --no-enable-swift-package-manager"
