Answer 2

As I found out Deep link support in flutter windows app is complicated. you should make custom Registry entries to associate your URI scheme with your app. you need add this library to windows app. this instruction helps you with it. and for handling it in your flutter app you should write some c++ code to port data you need to flutter.
this package port this sdk to flutter for mobile and web: flutter-branch-sdk

handling deep link in Universal Windows Applications (UWP) is much easier but It is in flutter dev channel and is not stable and supported by the other 3rd party packages yet.
you can activate uwp by this instruction and create uwp in your existing project by run this command:

flutter create --platforms=winuwp

for adding deep link in "winuwp/runner_uwp/appxmanifest.in" make these changes:

<Packages 
 ...
 xmlns:uap2="http://schemas.microsoft.com/appx/manifest/uap/windows10/2"
 xmlns:uap3="http://schemas.microsoft.com/appx/manifest/uap/windows10/3"
 IgnorableNamespaces="uap uap2 uap3 mp">
<Application>
<Application Id="App" ...
<Extensions>
    <uap3:Extension Category="windows.appUriHandler">
      <uap3:AppUriHandler>
        <uap3:Host Name="flungoportfolio.com" />
      </uap3:AppUriHandler>
  </uap3:Extension>
  </Extensions>
</Application>
</Application>
