ViewPadding class
A representation of distances for each of the four edges of a rectangle, used to encode the view insets and padding that applications should place around their user interface, as exposed by FlutterView.viewInsets and FlutterView.padding. View insets and padding are preferably read via MediaQuery.of.
For a generic class that represents distances around a rectangle, see the EdgeInsets class.
See also:
- WidgetsBindingObserver, for a widgets layer mechanism to receive notifications when the padding changes.
- MediaQuery.of, for the preferred mechanism for accessing these values.
- Scaffold, which automatically applies the padding in material design applications.
