I am getting above error messages while integrating angular-calender into my angular project.
please help. Thank you in advance.
I ran into similar problems when I was looking to get it figured out. I got it working by using the kitchen sink demo on this page: https://mattlewis92.github.io/angular-calendar/#/kitchen-sink
To make sure you have everything good to go, look at the "module.ts" tab of the kitchen sink demo. There you can see all the module imports. Make sure those imports are properly configured on your app-module.ts file. If you're missing any of the dependencies (I was missing flatpickr and ng-bootstrap) just npm install them
@callen1994 is right, you need to add the angularx-flatpickr package (or just delete the event editor code if your app doesn't need it, it's just for the demo)
npm install --save flatpickr angularx-flatpickr
This'll work.

i am not getting dates to select, can any one help me
@ramkumar-siriyala same thing happening here. Any workaround that you found?
@ramkumar-siriyala I found a work around
Just enable the date using range in the <input/> tag of template.html where the code resides for picking date
<input
class="form-control"
type="text"
mwlFlatpickr
[enable]="[{
from: '2020-04-01',
to: '2030-05-01'
}]"
[(ngModel)]="event.end"
(ngModelChange)="refresh.next()"
[altInput]="true"
[convertModelValue]="true"
[enableTime]="true"
dateFormat="Y-m-dTH:i"
altFormat="F j, Y H:i"
placeholder="Not set"
/>
