The example below may get you started. Visit the <a href="https://developer.wordpress.org/block-editor/developers/block-api/block-templates/" rel="nofollow ugc">WordpPress Block Editor Handbook</a> to learn more about supercharging your WordPress themes with blocks templates.
<pre><code><?php
if(in_array('advanced-bootstrap-blocks/advanced-bootstrap-blocks.php', apply_filters('active_plugins', get_option('active_plugins')))){ 
 // do stuff only if the Advanced Bootstrap Blocks plugin is active 
 add_action( 'init', 'advancedbootstrapblocks_register_page_template' );
 function advancedbootstrapblocks_register_page_template() {
 $post_type_object = get_post_type_object( 'page' );
 $isFluid = get_theme_mod( 'understrap_container_type' ) === 'container-fluid'; 
 $post_type_object->template = [
 [ 'advanced-bootstrap-blocks/container', 
 ['className'=>'py-5', 'isWrapped' => $isFluid, 'isFluid' => false ], 
 [
 [ 'advanced-bootstrap-blocks/row', 
 [],

Advanced Bootstrap Blocks

... and that's not saying much because the others were broken or terrible. Even still, this one is on the right track, and I'm happy to see that at least somebody is getting it right. Thanks for your hard work!

So far the best bootstrap block plugin

This is really well done, it does lack some features to become perfect, and has some issues with the editor (columns chaos if multiple classes are set) but it works perfectly. By far the fastest way to get Bootstrap into Gutenberg : THUMBS UP

Very usable !

Build responsive Bootstrap 4 layouts inside the Gutenberg editor.
