Module development and code questions

Here's my code.

I'm trying to populate a custom text field that has a default value with a new value thus:

function mytheme_views_pre_render(Drupal\views\ViewExecutable $view) {
if ($view->id() == "contacts" && $view->current_display == 'block_7') {
foreach ($view->result as $row) {
$cid = $row->_entity->id->value;
$cs = lgf_checksum_get($cid);
if ($cs) {
$row->_entity->nothing->setValue($cs);
}
}
}
}

It's throwing this error 

Hello,

I am trying to add the exact version of AnimateCSS module for a new module in the .info.yml dependencies.

My code is as follows:

I am  using "String overrides:" as indicated in settings.php file

example:

609 # $settings['locale_custom_strings_en'][''] = [
610 #   'forum'      => 'Discussion board',
611 #   '@count min' => '@count minutes',
612 # ];

These are working from php code; however when I use Drupal.t(....) in javascript code, the translations are not picked up.

I see that drupal.js has the code where it reads window.drupalTranslations (which is prepared by locale module)

I tried to look into this in browser console by calling
