Gutenberg is a great block editor but it does not come with a todo block.
You can now create to-do lists in WordPress Gutenberg editor. 
Your todo checkboxes will appear both on the frontend and backend. It will even keep the current state of the checkbox when shown on the frontend.
Logged-in users can save their checkbox selections (if enabled per checklist).
You can use this block to:
<ul>
<li>Add tasks to your posts and pages</li>
<li>Create a checklist of items</li>
<li>Let logged-in users save their selections</li>
<li>Set goals and track progress</li>
</ul>

Todo Block


Things I Wish:




I could use markdown to insert a checkbox, I should be able to type [] followed by a spacebar for example to insert or maybe [ ] followed by a spacebar



I could double tap enter to exit the block (instead of just keep creating new checkboxes)




Things I Like:




Read only option



No lag



Light in plugin size



It works and it's crisp... but needs some extra love.

Adds ToDo list block that shows checkboxes on frontend and backend of your site.
