Getting error " No provider for AlertIconAndTypesService!"

I am using clarity module with my angular 4 code. When using their alert box example, I am getting the above error

Example Code

<div class="alert alert-info">
    <div class="alert-items">
        <div class="alert-item">
            <div class="alert-icon-wrapper">
                <clr-icon class="alert-icon" shape="info-circle"></clr-icon>
            </div>
            <span class="alert-text">...</span>
            <div class="alert-actions">
                <a href="..." class="alert-action">Acknowledge</a>
                <a href="..." class="alert-action">Reset to green</a>
            </div>
        </div>
    </div>
    <button type="button" class="close" aria-label="Close">
        <clr-icon aria-hidden="true" shape="close"></clr-icon>
    </button>
</div>

As the error suggests, import the AlertIconAndTypesService service in your module

So in your app.module.ts file

import { AlertIconAndTypesService } from "clarity-angular/emphasis/alert/providers/icon-and-types-service";

....
@NgModule({
...
providers:['AlertIconAndTypesService']
...
})
