Onscreen virtual keyboard for Angular (https://angularjs.org/) using Material (https://material.angularjs.org/) and the Angular Virtual Keyboard by the-darc (https://github.com/the-darc/angular-virtual-keyboard) based on GreyWyvern VKI (http://www.greywyvern.com/code/javascript/keyboard).
Unfortunately the input
blur
listener is removed on state change, so the keyboard does not hide.
