title: Font size multiplier via AccessibilityManager
body: <p>I need the value of the font size multiplier, which is set by the accessibility settings of the system (iOS).</p>
  
  <p>Currently I achieve this by calling a method of <strong>AccessibilityManager.m</strong> via:</p>
  
  <pre><code>const AccessibilityManager = NativeModules.AccessibilityManager;
  console.log(AccessibilityManager.getMultiplier((value) =&gt; {
      console.log(value)
  }));
  </code></pre>
  
  <p>Is this a <strong>solid</strong> way or could someone suggest me a better approach? It should be usable as a part of a <strong>shared component</strong>.</p>
