{@inheritdoc}
protected AccessResult
blockAccess(AccountInterface $account)
Indicates whether the block should be shown.
Blocks with specific access checking should override this method rather than access(), in order to avoid repeating the handling of the $return_as_object argument.
buildConfigurationForm(array $form, FormStateInterface $form_state)
{@inheritdoc}
Creates a generic configuration form for all block types. Individual block plugins can add elements to this form by overriding BlockBase::blockForm(). Most block plugins should not override this method unless they need to alter the generic form elements.
blockForm($form, FormStateInterface $form_state)
{@inheritdoc}
validateConfigurationForm(array $form, FormStateInterface $form_state)
{@inheritdoc}
Most block plugins should not override this method. To add validation for a specific block type, override BlockBase::blockValidate().
blockValidate($form, FormStateInterface $form_state)
{@inheritdoc}
submitConfigurationForm(array $form, FormStateInterface $form_state)

Most block plugins should not override this method. To add submission handling for a specific block type, override BlockBase::blockSubmit().

array
build()
Builds and returns the renderable array for this block plugin.
If a block should not be rendered because it has no content, then this method must also ensure to return no content: it must then only return an empty array, or an empty array with #cache set (with cacheability metadata indicating the circumstances for it being empty).
