Hi,
I hope i am writing this on the right place 
I want to create a block with ACF, and so far it’s working in the backend, it gets renderd and i see the value. But if i want to communicate this to the front-end i get null.
as example, a simple title. Let me explain what i did so far: See code.
What is also strange and i dont get, when i var_dump $block or $title i get notting in return (front-end). In the back-end i see the information?! Does it has something to do with the render_callback and template?! I hope some one can explain this in dummy style, so i know what i did wrong 
functions.php
add_action('acf/init', 'my_acf_register_blocks');
function my_acf_register_blocks() {
// Check if ACF is active
if (function_exists('acf_register_block_type')) {
// Register a custom block
acf_register_block_type(array(
'name' => 'plainheader',
'title' => __('Plain Header'),
'description' => __('Plain Header'),
'render_callback' => 'render_plainheader_block',
'render_template' => get_template_directory() . '/resources/views/blocks/plainheader/plainheader.blade.php',
'enqueue_style' => get_template_directory_uri() . '/resources/styles/app.css',
'category' => 'media',
'icon' => 'images-alt2',
));
}
}
function render_plainheader_block($block) {
$fields = get_fields(); // Get all ACF fields
echo \Roots\view('blocks.plainheader.plainheader', [
'block' => $block,
'fields' => $fields,
]);
}
plainheader.blade.php( i cropped the code to only the title btw)
@php
/**
* Plainheader Block Template.
*
* @param array $block The block settings and attributes.
* @param string $content The block inner HTML (empty).
* @param bool $is_preview True during AJAX preview.
* @param (int|string) $post_id The post ID this block is saved to.
*/
$id = $block['id'] ?? 'plainheader';
if (!empty($block['anchor'])) {
$id = $block['anchor'];
}
$className = 'plainheader';
if (!empty($block['className'])) {
$className .= ' ' . $block['className'];
}
if (!empty($block['align'])) {
$className .= ' align' . $block['align'];
}
$title = get_field('title');
@endphp
<section id="{{ $id }}" class="{{ $className }}">
<div class="container">
<div class="lg:grid grid-cols-2 block relative">
<div class="header_title">
{{ $title }}
</div>
</div>
