I think you can use the VarDumper from Symfony instead.

Usage example I use in a future package:

private function formatValue(mixed $value): string
{
    if (is_string($value) && str_ends_with($value, '::class')) {
        $stringValue = $value;
    } else {
        $stringValue = VarExporter::export($value);
    }

    $indentedValue = preg_replace(
        '/^/m',
        str_repeat('    ', $this->indentLevel), // 4 spaces per indent level
        $stringValue,
    );

    return ltrim($indentedValue);
}
