[SPM] Identity mismatch error when plugin root directory name differs from Dart package name

Steps to reproduce

Have a Flutter plugin whose repository/folder name differs from its Dart package name — e.g., repo dir is NUXXXXX_DEVICE_PLUGIN_Lib, Dart package name is device_plugin.
Set up SPM support per the guide (Package.swift with name: "device_plugin")).
In the example app's pubspec.yaml, reference the plugin as a local path dependency:
Enable SPM and run the example app:

flutter config --enable-swift-package-manager
flutter run

Actual results

Expected behavior

SPM resolves the plugin package successfully and the app builds.

Actual results

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

You can also disable Swift Package Manager for the project by following these
instructions:
