The type Magento\Framework\View\Element\UiComponent\Control\ButtonProviderInterface was not found. Maybe you did not declare it correctly or list all dependencies?

The expression $this->getModelId() of type integer|null is loosely compared to true; this is ambiguous if the integer can be 0. You might want to explicitly use !== null instead.
