How do I get the submitted moderation state of a custom block?

Question

I am a bit new for Drupal and currently working on Drupal8. I need to implement custom restrictions for workflow. Basically i want to get the submitted value of moderation_state filed in mymodule_form_alte

Here are the things that i have tried but all returns Null. The strange thing is that the below method works for node but do not work for block_content

 function mymodule_form_alter($form, &$form_state, $form_id) {
   $formSate = $form_state->getValue('moderation_state')[0]['valye'];
   var_dump($formState); // Output : Null

   $formSate = $form['moderation_state']['widget']['#default_value'];
   var_dump($formState); // Output : return the default value of dropdown not the one that i have selected
}

Here is the moderation_state field

Answer 1

all most there try the following

// Get the current  entity.
$entity = $form_state->getFormObject()->getEntity();
$moderation_state = $entity->get('moderation_state')->getString();
// Do the things.

or in a submit or validation thing try to

// use dump() as it is way better 
dump($form_state->getValues()) // <-- and find in the array
