title: Flutter listview headers
body: <p>I want to make a listview with headers per day, like the google calendar and the google contacts. I couldn't find an example how to make something like this in a flutter view.
  So I want to have a header stick on the left side such as the date for the first item with that date till the next day gets on top and then the previous day has to continue to scroll. Should I work with a MultiChildLayoutDelegate like the animation example in the gallery or can I do this with the listview in some way?</p>
  
  <p>Edit: Made a package myself: <a href="https://pub.dartlang.org/packages/side_header_list_view" rel="nofollow noreferrer">https://pub.dartlang.org/packages/side_header_list_view</a></p>
