Topic: Toast stuck in transparent state

dxl pro asked 4 years ago

When I show a toast, it's stuck in a transparent estate with 0.5 opacity. It never transitions to full opacity, making the contents unreadable.

Hi Damian,

Sorry, I cant provide a screenshot to show a flicker as it is an animation.

To reproduce simply create a blank project with mdbpro v 7.5.2 an include the following as AppComponent

export class AppComponent {
 title = 'ng-uikit-pro-standard-compile-app';

 constructor(private toastrService: ToastService) {}
 showSuccess() {
    const options = { closeButton: true, toastClass: 'opacity' };
   this.toastrService.success('Info message', 'Success!', options);

And then the following in styles.scss:

.opacity {
 opacity: 1 !important;
#toast-container > mdb-toast-component.opacity,
#toast-container > mdb-toast-component.opacity > div {
opacity: 1 !important;

The flickering most commonly happens on the first call to the .success method on both the toast message fading in, and fading out.

We are already aware of that problem and it should be fixed in next version.

Which browser/version do you use?

Hi,I have found that changing the opacity as in the docs results in a flickering effect in the toast.How can I make the toast behave exactly as it does in the link you provided above?Thanks,John
