Adding it as shared service in the frontcontroller.
$di->setShared('flashmessage', function() { $flashmessage = new \frjf14\FlashMessage\CFlashMessage(); return $flashmessage; });
From the package Copy the css file: frjf14/cflashmessage/src/css/flashmessage.css to the webroot css folder: webroot/css/ then add the css to the frontcontroller $app->theme->addStylesheet('css/flashmessage.css'); or just link directly to the CSS file within the package $app->theme->addStylesheet('../vendor/frjf14/cflashmessage/src/css/flashmessage.css');
Now you can add flash messages as an example error message: $app->flashmessage->addError('An error message.'); and to display the message use $app->flashmessage->getFlashMessages(); to retrive the message(s) as html.
