How to remove debug banner with Flutter

How to remove debug banner with Flutter

In this tutorial you will learn how to remove the debug banner from your Flutter app. I find this debug banner to be quite annoying but luckily there is a one line fix for it.

To remove the debug banner set the following property on your MaterialApp widget:

debugShowCheckedModeBanner: false,

After adding this my MaterialApp widget code looks like this:

  title: 'Flutter Demo',
  theme: ThemeData(
    visualDensity: VisualDensity.adaptivePlatformDensity,
  debugShowCheckedModeBanner: false, // Remove Debug Banner
  home: MyHomePage(title: 'Flutter Demo Home Page'),

If you want the full source code, you can find it here.
