Flexi Plugins currently offers two type of blocks.
1) Flexi Forms
2) Flexi Gallery
and both of this blocks can be found on block list at editor.

Flexi Form
This block will help you to build the submission form for the visitors. You can toggle between the different ready form fields. But this only list the basic and most used form fields. If you want more complex form with full advance control use form shortcodes. You have to read documentation before using it.
For easiness of the user, the dynamic updated shortcode is generated just for reference to have idea over the background.

Flexi Gallery
This block will help you to quickly generate a gallery for you without any shortcode knowledge. Just toggle between the set of features available in the editor controls area usually available at the right side of the screen. Controls are activated only when mouse is focused at the block editor.
Since due to GUI option all the features are not implemented. So to have full controls over the gallery with advance features do use the gallery shortcode.
For easiness of the user, the dynamic updated shortcode is generated just for reference to have idea over the background.
