    This setup is only for MacOS. I don't have a windows/linux machine to test.
Clone FDE repo
cd ~
git clone https://github.com/google/flutter-desktop-embedding
Switch to flutter master
flutter channel master
Pull all latest changes
Because current master is not pointing to latest commit
cd ~/flutter
git pull origin master
Set env variable to enable desktop builds
This enables experimental features. Add it to your .profile or rc file if you don't want to run this for every terminal session.
export ENABLE_FLUTTER_DESKTOP=true
Finish setup
flutter doctor
It shoulds say there is one connected device
Create new project
This doesn't have to be inside FDE folder
flutter create hello_world
cp -R ~/flutter-desktop-embedding/example/macos hello_world/macos
[obsolete] Change FDE path
Note: This step is not required anymore because FDE_ROOT has been eliminated from flutter-desktop-embedding project. Thanks @stuartmorgan for the heads up!
Open hello_world/macos/Runner.xcodeproj/project.pbxproj in a code editor. You can do this from Xcode as well.
Replace this
FDE_ROOT = $PROJECT_DIR/../..;

with this
FDE_ROOT = $HOME/flutter-desktop-embedding;

There will be two instances to replace.
Override platform
Flutter framework code doesn't cover macos/linux/windows platforms yet.
So we have to override platform with an existing one like this:
import 'package:flutter/material.dart';
import 'package:flutter/foundation.dart'
    show debugDefaultTargetPlatformOverride;

void main() {
  debugDefaultTargetPlatformOverride = TargetPlatform.fuchsia;

  runApp(MyApp());
}
Run or build
export ENABLE_FLUTTER_DESKTOP=true

flutter run -d macos

flutter build macos
cd build/macos/Build/Products/Release/
IDE support
export ENABLE_FLUTTER_DESKTOP=true

open -a Android\ Studio

open -a Visual\ Studio\ Code
