Please try this code.

/**

* #param array $settings Settings.
* #return array

function dimative_shipping_instance_form_add_extra_fields( $settings ) {
$settings['shipping_extra_field_title'] = array(
'title' => esc_html__( 'Shipping method title', 'zincheco' ),
'type' => 'text',
'placeholder' => esc_html__( 'Please add shipping method title', 'zincheco' ),
'description' => '',
);

Answer 2

In case if someone is looking how to get the value using #Өлзийбат-Нансалцог code example. I was able to retrieve it this way:
//Get Shipping rate object
//$method->id is the ID of the shipping method.
//In my case I used that in cart-shipping.php template
$WC_Shipping_Rate = new WC_Shipping_Rate($method->id);
// Returned value is flat_rate:1
$shipping_rate_id = $WC_Shipping_Rate->get_id();
//Replacing : with underscore to have the id in format of flat_rate_1
$shipping_rate_id = str_replace(':', '_', $shipping_rate_id);
//Get the description field value
//Since the value is stored inside options table use get_option() method
get_option('woocommerce_'.$shipping_rate_id.'_settings')['shipping_extra_field_description']

Here is the code for getting the value.
if ( ! function_exists( 'dimative_shipping_method_description' ) ) {
/**
* Function will print shipping method description.
*
* #param object $method Shipping method object.
* #param int $index Shipping method index.
* #return void
*/
function dimative_shipping_method_description( $method, $index ) {
$dimative_method_fields = get_option( 'woocommerce_' . $method->method_id . '_' . $method->instance_id . '_settings' );
$dimative_method_allowed_html = array(
'p' => array(
'class' => array(),
),
'strong' => array(),
'b' => array(),
'a' => array(
'href' => array(),
),
'span' => array(
'class' => array(),
),
);
// Shipping method custom description.
if ( $dimative_method_fields['shipping_extra_field_description'] ) {
?>
<div class="method-description"><?php echo wp_kses( $dimative_method_fields['shipping_extra_field_description'], $dimative_method_allowed_html ); ?></div>
<?php
}
}
add_action( 'woocommerce_after_shipping_rate', 'dimative_shipping_method_description', 1, 2 );
}
