/// The user can transform the child by dragging to pan or pinching to zoom.

/// By default, InteractiveViewer may draw outside of its original area of the
/// screen, such as when a child is zoomed in and increases in size. However, it
/// will not receive gestures outside of its original area. To prevent
/// InteractiveViewer from drawing outside of its original size, wrap it in a
/// [ClipRect]. Or, to prevent dead areas where InteractiveViewer does not
/// receive gestures, be sure that the InteractiveViewer widget is the size of
/// the area that should be interactive. See
/// [flutter-go](https://github.com/justinmc/flutter-go) for an example of
/// robust positioning of an InteractiveViewer child that works for all screen
/// sizes and child sizes.

/// The [child] must not be null.

/// See also:
/// * The [Flutter Gallery's transformations demo](https://github.com/flutter/gallery/blob/master/lib/demos/reference/transformations_demo.dart),
