angularjs - Dynamically loading a material theme in angular

Question

I'm building an Angular application using Angular Material. One of the first steps in the application is that the user logs in. Next, the system loads from the backend the theme made by that user's company.

However, when the backend responds with the Theme information, I am not able to get it into the system. The $mdThemingProvider, which allows you to set themes, does not seem to be available from inside a Controller and the $mdTheming service itself does not have options for modifying the themes in the system.

Is there any way to dynamically load new themes into an Angular Material application?

Answer 1

As of version 1.0.5 of angular-material:

1. Add

   reload: generateTheme 
   

   in themingProvider function (angular-material.js line 4840 - the generateTheme function is already present in angular-material.js, we just need a way to call it)

2. In config function:

   angular.module('my-module').config(function ($provide, $mdThemingProvider) {
    $mdThemingProvider.generateThemesOnDemand(true);
    $provide.value('themeProvider', $mdThemingProvider);});
   

3. In your controller, inject themeProvider and now you can do something like:

   //create new theme
   themeProvider.theme('custom')
     .primaryPalette('pink')
     .accentPalette('orange')
     .backgroundPalette('yellow');
   
   //reload the theme
   themeProvider.reload('custom');
   
   //optional - set the default to this new theme
   themeProvider.setDefaultTheme('custom');
