How to programmatically access custom field in workflow transition

Please check workflow.api.php.
When you enable workflow_devel module, each of the hooks in workflow.apiphp is called.
The $transition object contains multiple gettes and setters, as per the WorkflowTransitionInterface.
E.g., $transition->getTargetEntity() gives the main entity. $transition->getToSid() and getToState contain the new Stae and StateID.

Or you can use the 'magic' functions:
- $value = $transition->{$field_name}->value;
- $value = $transition->{$field_name}->__get('foo');
- $transition->{$field_name} = $values[$field_name]; using form_state->values()

With apologies, I'm still stuck.

I understand how I can get to the transition object. I can also get the "To" State via $transition->getToState().
How do I get a value of the field defined on the workflow form from there? E.g. the field system name is "field_reassign_to".

$transition->getToState()->get("field_reassign_to") does not return anything, even though the transition is performed with this field populated in the workflow form.

Thank you!

Your field is not in the state, but on the transition.
(Indeed, the naming of the added field 'Workflow State' may be confusing)

So, try:

$field_name = 'field_reassign_to'
$transition->{$field_name}->value;
or
$transition->get{$field_name}->value;

Thisis like any entity with fields added via field UI.

Thank you, got it working!
