ng-flow upload file - how to add to TOP of ng-repeat list

I'm using the angular ng-flow component for file upload and it's working great besides a few nuances. I'd love to be able to have the new files that I try to upload put on the top of the list rather than on the bottom of the list so it's clear for users the latest one that has been uploaded. I tried using the angular order by command but that doesn't seem to work unless it's an existing list compared to adding a new file to the list.

Basically I create a new row for each file once it's complete and print out the file details:

<tr ng-repeat="file in $flow.files | orderBy:'file.name'" ng-hide="file.isComplete()">

the list looks like this before upload:

old1
old2
old3

then I add a new file and I see:

old1
old2
old3
new1

when I'd like:

new1
old1
old2
old3

This is probably more of a question about using Angular's ng-repeat functionality for new items added to the list.

Solution

To use orderBy filter, you need just let the property in filter, as the following:

<tr ng-repeat="file in $flow.files | orderBy: 'name'" ng-hide="file.isComplete()">

EDIT

Since you want to sort your items by chronological order, it should give you the expected result:

<tr ng-repeat="file in files | orderBy: '$index': true">

Here's is a snippet working:

var app = angular.module('app', []);

app.controller('mainCtrl', function($scope) {
  $scope.files = [  
     {  
        "id":1,
        "name":"Old1"
     },
     {  
        "id":2,
        "name":"Old2"
     },
     {  
        "id":3,
        "name":"Old3"
     }
  ];

  var increment = 1;
  $scope.push = function (name) {
    $scope.files.push({ "id": increment + 3, "name": name + increment++ })
  }
});
