Module doesn't support revision

Hello, mahipal46

Thank you for contributing the patch. I have checked and basic functionality working. But I can see compatibility issues with the content_moderation module.
Please check fixes in the attached patch.

Patch without _parent_ fields

Initial views support for widget_field_revision

Proper patch with revision support.

ContentModeration support in WidgetContentModerationHandler.php

Fix empty revision information for existing widgets

Third-party modules should not extend handlers implemented from Drupal core. They are considered internal, and they will be marked as final in future Drupal core versions. That is described in Drupal 8 and 9 backwards compatibility and internal API policy (backend).

Particular entity handlers should not be considered part of the public API. The interfaces which define those entity handlers though are part of the supported API.

Drupal\content_moderation\Entity\Handler\ModerationHandler is an entity handler class.

Thank you for feedback, kiamlaluno
Fixed.

Add /revisions tab. Add functional to revert and delete revisions.

Fixed patch:
- created should be revisionable
- type should not be revisionable
- status index

Fixed patch:
- error in a translated version

Fixes for failed tests.

Hi,

Would it be possible to make a reroll of the last patch for Drupal 8.9.x?

Here's my attempt of porting the patch for 8.x-1.4.
Works on Drupal 9.5

Hope that helps somebody.

Patch edit : add 'isModeratedEntity()' function in moderation handler
