title: How to achieve Text masking background in Flutter?
body: <p><a href="https://i.stack.imgur.com/JladW.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/JladW.png" alt="example of desired behaviour" /></a></p>
  <p>How can I achieve this effect in Flutter programmatically?
  I've tried <code>ShaderMask</code> but didn't find the right tool yet.</p>
  <p>Blue background in my case is a <code>ClipPath</code> on a <code>Container</code>.
  Both, <code>Text</code> and <code>Container</code> are in the <code>Stack</code>, so the text is <code>Positioned</code></p>
