result from Await DisplayAlert Xamarin.Forms

Xamarin has awaitable DisplayAlert method which returns Task<bool>.

I have static class Helpers where i want to write code like this:

public static bool DisplayAlert(string title, string message, string accept, string cancel){
    //return answer from Page.DisplayAlert(title, message, accept, cancel);
}

This method will be called from other parts of the app like:

public ... SomeMethod(){
    // some code
    bool result = DisplayAlert(...);
    // some code
}

I want to avoid async/await in SomeMethod. (How you can wait a response from a user asynchronously?!!!!!!)

I tried await Page.DisplayAlert(...), task.Wait() and another. But Task was executed asynchronously with no return value. Or application freezes forever without displaying DisplayAlert.

How to do it? What's the best practice?

If you want SomeMethod to remain Synchronous, this is one option:

public async static Task<bool> DisplayAlert(string title, string message, string accept, 
string cancel){
 return await Page.DisplayAlert(title, message, accept, cancel);
}

// SomeMethod will run Synchronously
public boolean SomeMethod(){
  bool result = StaticClass.DisplayAlert(..).Result;
  return result;
}

EDIT: Fixed some syntax
