you have to include at a minimum these to your _Host.cshtml
<link href="_content/FlatpickrBlazor/flatpickr.min.css" rel="stylesheet" />
<script src="_content/FlatpickrBlazor/flatpickr.min.js"></script>
<script src="_content/FlatpickrBlazor/flatpickr.blazor.js"></script>
to add a locale (specify in your FlatpickrOptions variable) add the following script:
<script src="_content/FlatpickrBlazor/l10n/de.js"></script>
and change the "de.js" with your choosed language
to add the plugins, you have to include the script and style files. e.g. for the month select plugin:
<link href="_content/FlatpickrBlazor/plugins/monthSelect/style.css" rel="stylesheet" />
<script src="_content/FlatpickrBlazor/plugins/monthSelect/index.js"></script>
