How can I use a variable on my extended twig page (Symfony)?

I return data with my Controller.php to my twig template:

  return $this->render('list.html.twig', ['page' => $page]);

On my list.html.twig I can output my variable:

{{page.name}}

But I extend my base.html twig on my list.html.twig:

{% extends 'base.html.twig' %}

So when I want to output my variable on my base.html.twig:

{{page.name}}

Then I get the error message:

Uncaught PHP Exception Twig_Error_Runtime: "Variable "page" does not exist." at /Users/work/project/templates/base.html.twig line 70

On your base.html.twig add a block like 

{% block page %}{% endblock page %}

and on list.html.twig add {% block page %}{{page.name}}{% endblock page %}

So you could have a file like base.html.twig

<html>
    <body>
        <h1>{% block page %}{% endblock page %}
        <p>{% block content%}{% endblock content %}</p>
    </body>
</html>

and a list.html.twig like

{% extends 'base.html.twig' %}

{% block page %}{{ page.name }}{% endblock page %}
{% block content %}errything else for page here{% endblock content %}

and it'd be valid and would overwrite the page block for base.html.twig through inheritance.

Added a twigfiddle example https://twigfiddle.com/d1hmo9
