        $this->options = new BarChartOptions();
        $this->options->setBars('horizontal');

The method setBars() does not exist on CMEN\GoogleChartsBundle\GoogleCharts\Options\ChartOptionsInterface. It seems like you code against a sub-type of CMEN\GoogleChartsBundle\GoogleCharts\Options\ChartOptionsInterface such as CMEN\GoogleChartsBundle\GoogleCharts\Options\ColumnChart\Material\ColumnChartOptions or CMEN\GoogleChartsBundle\GoogleCharts\Options\BarChart\Material\BarChartOptions.

    }

    public function getPackage(): string
    {
        return 'bar';

    public function getLibrary(): string

    public function getType(): string
    {
        return 'Bar';
    }

    public function getOptions(): BarChartOptions
    {
        return $this->options;

The expression return $this->options returns the type CMEN\GoogleChartsBundle\GoogleCharts\Options\ChartOptionsInterface which includes types incompatible with the type-hinted return CMEN\GoogleChartsBundle\GoogleCharts\Options\BarChart\Material\BarChartOptions.
