Just a small update, the acf-block-icon plugin is not actually working for me.
I did a little digging into the ACF code and it looks like a string starting with <svg is being detected, but only for the icon property and not if you’ve set the icon via icon['src']. I was setting my icon like this because I want to have a custom foreground color:
acf_register_block_type( array(
// ...
'icon' => array(
'foreground' => '#7bb12d',
'src' => '<svg xmlns="http://www.w3.org/2000/svg" width="24" height="24" viewBox="0 0 24 24"><path d="M0,0H24V24H0Z" fill="none"/><polygon points="20 18 4 18 4 20 20 20 20 18"/><path d="M22,3H2A1,1,0,0,0,1,4V15a1,1,0,0,0,1,1H22a1,1,0,0,0,1-1V4A1,1,0,0,0,22,3ZM21,5V9.92l-3.38-2.7a1,1,0,0,0-1.24,0L12,10.74,8.6,8.2a1,1,0,0,0-1.15,0L3,11.13V5ZM3,14v-.46l5-3.32L11.4,12.8a1,1,0,0,0,1.22,0L17,9.28l4,3.2V14Z"/></svg>',
),
I’m looking to see if I can add a filter via JS on blocks.registerBlockType to handle the icon with foreground color for the time being.
