Answer 1

You did ask about using the simple toast call. Would you mind trying a custom toast show like the demo and add classes to the template?

JS

$mdToast.show(
  controller: 'ToastCtrl',
  templateUrl: 'views/shared/toast.html',
  hideDelay: 6000,
  position: $scope.getToastPosition()
)

TEMPLATE

<md-toast class="flash">
  <span flex>Custom toast!</span>
  <md-button ng-click="closeToast()">
   Close
  </md-button>
</md-toast>

CSS

md-toast.flash {
  background-color: red;
  color: white;
}

CONTROLLER (COFFEE)

'use strict'

###*
 # @ngdoc function
 # @name angularApp.controller:ToastCtrl
 # @description
 # # ToastCtrl
 # Controller of the angularApp
###
angular.module('angularApp')
  .controller 'ToastCtrl', ($scope) ->
    $scope.closeToast = ()->
      $mdToast.hide()

For a correct implementation, please use rlay3s solution below :)!

OUTDATED:
I had problems displaying custom text with jhblacklocks solution, so I decided to do it like this using 'template':

var displayToast = function(type, msg) {

    $mdToast.show({
        template: '<md-toast class="md-toast ' + type +'">' + msg + '</md-toast>',
        hideDelay: 6000,
        position: 'bottom right'
    });
};

I also added the different types in my .css file:

.md-toast.error {
    background-color: red;
}

.md-toast.success {
    background-color: green;
}

Don't know if this is the most beautiful approach, but I don't need a template files for each dialog type and displaying custom text is really easy.

I first favoured the solution but I don't like setting up a theme in the theme provider just for a toast. So how about this solution:

JS (Coffee)

   if error
      message = ''

      if error.reason is 'Incorrect password'
        message = 'Email and password combination is incorrect'
      if error.reason is 'User not found'
        message = 'No account found with this email address'

      $mdToast.show(
        templateUrl:  'client/modules/toasts/toastError.html'
        hideDelay:    3000
        controller: ( $scope ) ->
          $scope.message    =  message
          $scope.class      = 'error'
          $scope.buttonLabel = 'close'
          $scope.closeToast = ->
            $mdToast.hide()
      ).then( ( result ) ->
        if result is 'ok'
          console.log('do action')
      )

and then HTML (JADE)

md-toast(ng-class="class")
  span(flex) {{message}}
  md-button.md-action(ng-click="closeToast()") {{buttonLabel}}

I tried to use the locals option to pass variables to the controller, but for some reason they are not injected.(https://material.angularjs.org/latest/#/api/material.components.toast/service/$mdToast check list of options under show function)

Then last the CSS (STYLUS)

md-toast.success
  background-color    green

md-toast.error
  background-color    red

Summary: there is on template in this case which you can give custom placeholders which you prefill in your controller. This solution works for me.
