title: Flutter creating new line doesn't work when i read text from asset
body: <p>In our application we have some data as text which them stored into <code>assets</code> folder inside <code>lib</code> directory, as we know <code>\n</code> can create new line between text and we can ever use into <code>Text</code> widget, for example</p>
  <pre class="lang-dart prettyprint-override"><code>Text('Hello \n World),
  </code></pre>
  <p>result:</p>
  <pre><code>Hello
  World
  </code></pre>
  <p>whats my issue?</p>
  <p>as i said we stored texts into files and when i try to read them line by line with this code:</p>
  <pre class="lang-dart prettyprint-override"><code>  Future&lt;Sampletext&gt; _resolveTexts() async {
      final List&lt;String&gt; lines= [];
  
      await rootBundle
          .loadString('assets/sample.txt')
          .asStream()
          .transform(const LineSplitter())
          .forEach((element) {
        lines.add(element);
      });
  
      /*...*/
    }
  </code></pre>
  <p><code>\n</code> couldn't create new line and its also is into texts, for example:</p>
  <pre class="lang-dart prettyprint-override"><code>Text(lines[0]),
  </code></pre>
  <p>result:</p>
  <pre><code>Hello \n World
  </code></pre>
