-//# Desktop Flutter Example
-//
-//This is the standard Flutter template application, modified to run on desktop.
-//
-//The `linux` and `windows` directories serve as early prototypes of
-//what will eventually become the `flutter create` templates for desktop, and will
-//be evolving over time to better reflect that goal. The `macos` directory has
-//now become a `flutter create` template, so is largely identical to what that
-//command creates.
-//
-//## Building and Running
-//
-//See [the main project README](../README.md).
-//
-//To build without running, use `flutter build macos`/`windows`/`linux` rather than `flutter run`, as with
-//a standard Flutter project.
-//
-//## Dart Differences from Flutter Template
-//
-//The `main.dart` and `pubspec.yaml` have minor changes to support desktop:
-//* `debugDefaultTargetPlatformOverride` is set to avoid 'Unknown platform'
-//exceptions.
-//* The font is explicitly set to Roboto, and Roboto is bundled via
-//`pubspec.yaml`, to ensure that text displays on all platforms.
-//
-//See the [Flutter Application Requirements section of the Flutter page on
-//desktop support](https://github.com/flutter/flutter/wiki/Desktop-shells#flutter-application-requirements)
-//for more information.
-//
-//## Adapting for Another Project
-//
-//Since `flutter create` is not yet supported for Windows and Linux, the easiest
-//way to try out desktop support with an existing Flutter application on those
-//platforms is to copy the platform directories from this example; see below for
-//details. For macOS, just run `flutter create --macos .` in your project.
-//
-//Be sure to read the [Flutter page on desktop
-//support](https://github.com/flutter/flutter/wiki/Desktop-shells) before trying to
-//run an existing project on desktop, especially the [Flutter Application Requirements
-//section](https://github.com/flutter/flutter/wiki/Desktop-shells#flutter-application-requirements).
-//
-//### Coping the Desktop Runners
-//
-//The 'linux' and 'windows' directories are self-contained, and can be copied to
-//an existing Flutter project, enabling `flutter run` for those platforms.
-//
-//**Be aware that neither the API surface of the Flutter desktop libraries nor the
-//interaction between the `flutter` tool and the platform directories is stable,
-//and no attempt will be made to provide supported migration paths as things
-//change.** You should expect that every time you update Flutter you may have
-//to delete your copies of the platform directories and re-copy them from an
-//updated version of flutter-desktop-embedding.
-//
-//### Customizing the Runners
-//
-//See [Application Customization](App-Customization.md) for premilinary
-//documenation on modifying basic application information like name and icon.
-//
-//If you are building for macOS, you should also read about [managing macOS
-//security configurations](../macOS-Security.md).
