How to position elements to the right in md-toolbar?

Question

I am using FAB speed dial within a toolbar. However I am unable to have it floating to the right of the toolbar. I've tried float: right with no luck. Also, tried flex offset="55", but this doesn't work when the window is resized. Essentially, regardless of the window size, I would like the button sitting on the far right within the blue toolbar container.

See photo and code below:

<md-toolbar layout-fill layout-padding layout="row" style="background-color: #3F51B5;color:white;text-align:text-center;">
    <div layout="row">
        <i class="fa fa-users fa-2x" flex></i>
        <h1 class="md-title" style="color:white">Org Chart</h1>                                 
    </div>  
    <div class="lock-size" flex offset="55">
        <md-fab-speed-dial md-direction="left" ng-class="md-fling">
            <md-fab-trigger>
                <md-button aria-label="menu" class="md-fab md-accent">
                    <md-tooltip>
                      Actions
                    </md-tooltip>
                    <md-icon md-svg-src="img/icons/ic_view_module_48px.svg"></md-icon>
                </md-button>
            </md-fab-trigger>
            <md-fab-actions>
                <md-button aria-label="view" class="md-fab md-raised md-mini" >
                    <md-tooltip>
                      View Chart
                    </md-tooltip>                               
                    <md-icon md-svg-src="" style="color:black" ng-show="cDP.read" ng-click="paneShowFn('read')"></md-icon>
                </md-button>
                <md-button aria-label="add" class="md-fab md-raised md-mini" >
                    <md-tooltip>
                      Add Chart
                    </md-tooltip>                               
                    <md-icon md-svg-src="img/icons/ic_add_48px.svg" style="color:black" ng-show="cDP.insert" ng-click="paneShowFn('insert')"></md-icon>
                </md-button>
                <md-button aria-label="Settings" class="md-fab md-raised md-mini" >
                    <md-tooltip>
                      Security Access
                    </md-tooltip>                               
                    <md-icon md-svg-src="img/icons/ic_add_48px.svg" style="color:black" ng-show="cDP.permission" ng-click="paneShowFn('permission')"></md-icon>
                </md-button>                                
                <md-button aria-label="edit" class="md-fab md-raised md-mini" style="color:black" ng-show="cDP.update" ng-click="paneShowFn('update')">
                    <md-tooltip>
                      Edit Chart
                    </md-tooltip>                               
                    <md-icon md-svg-src="img/icons/ic_edit_48px.svg" style="color:black"></md-icon>
                </md-button>                                
            </md-fab-actions>
        </md-fab-speed-dial>
    </div>  
</md-toolbar>

Answer 1

Or you can use a class for that:

.fill-space {
  // This fills the remaining space, by using flexbox.
  // Every toolbar row uses a flexbox row layout.
  flex: 1 1 auto;
}

<md-toolbar color="primary">
  <span>Application Title</span>

  <!-- This fills the remaining space of the current row -->
  <span class="fill-space"></span>

  <span>Right Aligned Text</span>
</md-toolbar>

This solution is also taken from a spec.
