Did I miss anything? (I'm looking to develop a desktop app so not android emulator / ios emulator)
Whatever instructions you are following are out of date; ENABLE_FLUTTER_DESKTOP hasn't been the supported or documented way to enable experimental desktop support for several months (and the legacy code for it was recently removed). You need to enable it with flutter config as documented in the official instructions
Just Enable flutter desktop
flutter config --enable-macos-desktop

If this issue occurs both on Simulator and physical device, it's possible that timeouts in the Observatory port as mentioned on this thread. Try upgrading the Flutter version that you're using and see if it solves the issue. If it persists, run flutter run --profile --verbose to see more details on what's causing the issue.
I installed everything but when I run flutter doctor then this error occurs.

you can ignore those errors if you are going to use vscode as your IDE.
The answer to this error is:
flutter channel dev
flutter upgrade
flutter config --android-studio-dir="C:\Program Files\Android\Android Studio"
flutter doctor -v
when I run these 4 commands then this error will automatically solve.
flutter run -d all will start the application on android and iOS Simulators but won't start chrome.
Any Ideas?
Here is my flutter doctor output if that matters:

I think this is intended behavior, the same way that if you type flutter run -d all when no other device than Chrome and the web server are available, it outputs No devices found. I guess it's because the web support is still experimental. The only way is flutter run -d chrome.
My Flutter App is not compiling because of this error:
Couldn't read file Instance of 'ErrorHandlingFile' even though it
exists. Please verify that this file has read permission and try again
I tired switching channels and changing versions but nothing has worked yet.

Had the same problem after upgrade to beta channel.
Found that this error message just a top of an iceberg, real problem is in one of your plugins.
Read the discussion in this issue to manually debug your application or wait for fix which will result in an appropriate error message.
If you are lucky - simple flutter pub upgrade will solve the issue for your project.
If not, as a hot-fix you can downgrade your flutter version.
I am trying to create a Flutter Plugin following this: https://flutter.io/developing-packages/#step-1-create-the-package

Update: I have added the plugins Dart and Flutter to Android Studio(now Flutter doctor is all checkmarks), but still no run button. Note that this is a plugin generated. I am able to create a new Flutter project, but for this I dont know how to run the example apps?
I can run the example code with flutter run but opening the project in Android Studio do not show any run button?
