// Flutter code sample for Scaffold

// This example shows a [Scaffold] with a [body] and [FloatingActionButton].
// The [body] is a [Text] placed in a [Center] in order to center the text
// within the [Scaffold]. The [FloatingActionButton] is connected to a
// callback that increments a counter.
//
// ![The Scaffold has a white background with a blue AppBar at the top. A blue FloatingActionButton is positioned at the bottom right corner of the Scaffold.](https://flutter.github.io/assets-for-api-docs/assets/material/scaffold.png)
