Displays a dialog above the current contents of the app.
This function typically receives a Dialog widget as its child argument. Content below the dialog is dimmed with a ModalBarrier.
Returns a Future that resolves to the value (if any) that was passed to
Navigator.pop when the dialog was closed.
See also:
- SimpleDialog, which handles the scrolling of the contents but has no
actions. - AlertDialog, for dialogs that have a row of buttons below the body.
- Dialog, on which SimpleDialog and AlertDialog are based.
