The method setTitle() does not exist on Firegento\DevDashboard\Block\Adminhtml\Dashboard\Configuration. Since you implemented __call, consider adding a @method annotation.

        $this->_resetRequestParams();
    }

    public function _prepareRequestParams()
    {
        $this->originalParams = $this->getRequest()->getParam('section');
        $this->getRequest()->setParam('section', 'dev');

The method setParam() does not exist on Magento\Framework\App\RequestInterface. Did you maybe mean setParams()?
