I have a problem with an icon svg in angular-material , when I load my page the icon loads correctly with the following code: <md-icon md-svg-icon="{{ aaa.stat }}" aria-label="Icons Status"></md-icon> I am making use of the image by means of an object:
$scope.aaa = {
stat: "images/en-espera.svg"
}
As you can see in the image the icon is shown correctly, but when I go to the home and return to this view the icon seems to be placed a transparent background ...
