# padding property

WindowPadding padding

The number of physical pixels on each side of the display rectangle into which the application can render, but which may be partially obscured by system UI (such as the system notification area), or or physical intrusions in the display (e.g. overscan regions on television screens or phone sensor housings).

When this changes, onMetricsChanged is called.

See also:

- `WidgetsBindingObserver`, for a mechanism at the widgets layer to observe when this value changes.
- `MediaQuery.of`, a simpler mechanism for the same.
- `Scaffold`, which automatically applies the padding in material design applications.

## Implementation

    WindowPadding get padding => _padding;
