title: how to make a circular indicator widget as dots as a widget in my flutter app?
body: <p>I am looking to create an indicator widget for my pageview app, that means that It will be inside my widget tree.</p>
  <p>What I have remarked is that When I use
  PageViewIndicator class, it's automatically placed either in bottom or centre but when I place it in the center, for example, it hides my fields thing that I don't want, so what do you think?</p>
  <p>I have used This</p>
  <pre class="lang-dart prettyprint-override"><code>PageIndicatorContainer(
    pageView: PageView(
      children: customWidgetLists,
      controller: controller,
    ),
    align: IndicatorAlign.Center,
    length: 4,
    indicatorSpace: 20.0,
    padding: const EdgeInsets.all(10),
    indicatorColor: Colors.white,
    indicatorSelectorColor: Colors.blue,
    shape: IndicatorShape.circle(size: 12),
    // shape: IndicatorShape.roundRectangleShape(size: Size.square(12),cornerSize: Size.square(3)),
    // shape: IndicatorShape.oval(size: Size(12, 8)),
  }
  </code></pre>
  <p>Everything works fine, just I want the dots to be in the centre of the screen and not cover the other widgets because it did.</p>
