How to make text as big as the width allows in flutter : <p>I have a Container where I need to show a barcode (it's a app for virtual fidelity cards) and I'd love to have the barcode to be as wide as possible on the screen.
For now I set the font size at a reasonable size that suits all devices, but it's only temporary of course.
How can I solve this? This is the code I am using for building the Widget.</p>

<pre><code>@override
Widget build(BuildContext context) {
  return Scaffold(
      appBar: AppBar(
      title: Text(_title),
    ),
    body: Container(
    padding: const EdgeInsets.all(12.0),
    child: Column(
      children: &lt;Widget&gt;[ 
        SizedBox(
          width: double.infinity,
          child: Text(_barcode, style: TextStyle(fontFamily: 'Code128', fontSize: 90.0))
        ),
        Text(_barcode, style: TextStyle(fontSize: 40.0))
        ]
      ),
    )
  );
}
</code></pre>
