<p dir="auto">Why this framework using Dart ? not using more stable and robust like TypeScript or ES6 Javascript ?<br>
Look at Angular and other TypeScript based framework, it stable and easy to understand for large team and beginner.</p>
<p dir="auto">So any plan to leave Dart and using TypeScript language ?</p>
<p dir="auto">Hi, I don't know to ask for help for implementation so I fire an issue. If you find this not appropriate, please delete. Thanks.</p>
<p dir="auto">In iOS, we have a <code class="notranslate">UITabBarController</code> which stays permanently at the bottom of the screen when we push to a new ViewController.</p>
<p dir="auto">In iOS, we have a UITabBarController which stays permanently at the bottom of the screen when we push to a new ViewController.</p>
<p dir="auto">In Flutter, we have a <code class="notranslate">bottomNavigationBar</code> of a <code class="notranslate">Scaffold</code>. However, unlike iOS, when we <code class="notranslate">Navigator.push</code> to a new screen, this <code class="notranslate">bottomNavigationBar</code> disappears.</p>
<p dir="auto">In my app, I want to fulfil this requirement: Home screen has a <code class="notranslate">bottomNavigationBar</code> with 2 items (<em>a</em> &amp; <em>b</em>) presenting screen <em>A</em> &amp; <em>B</em>. By default, screen <em>A</em> is displayed. Inside screen <em>A</em>, there is a button. Tap that button,  <code class="notranslate">Navigator.push</code> to screen <em>C</em>. Now in screen <em>C</em>, we can still see the <code class="notranslate">bottomNavigationBar</code>. Tap item <em>b</em>, I go to screen <em>B</em>. Now in screen <em>B</em>, tap item <em>a</em> in the <code class="notranslate">bottomNavigationBar</code>, I go back to screen <em>C</em> (not <em>A</em>, <em>A</em> is currently below <em>C</em> in the navigation hierarchy).</p>
<p dir="auto">How can I do this? Thanks, guys.</p>
<p dir="auto">I'm including some pictures for demonstration:</p>
