SingletonFlutterWindow class

Deprecated. Will be removed in a future version of Flutter.

This class is deprecated to prepare for Flutter's upcoming support for multiple views and eventually multiple windows.

This class has been split into two classes: FlutterView and PlatformDispatcher. A FlutterView gives an application access to view-specific functionality while the PlatformDispatcher contains platform-specific functionality that applies to all views.

This class backs the global window singleton, which is also deprecated. See the docs on window for migration options.

See also:

  • FlutterView, which gives an application access to view-specific functionality.
  • PlatformDispatcher, which gives an application access to platform-specific functionality.

onAccessibilityFeaturesChanged VoidCallback?
A callback that is invoked when the value of accessibilityFeatures changes.

padding ViewPadding
The number of physical pixels on each side of the display rectangle into which the view can render, but which may be partially obscured by system UI (such as the system notification area), or physical intrusions in the display (e.g. overscan regions on television screens or phone sensor housings).
no setterinherited

no setterinherited
viewPadding ViewPadding
The number of physical pixels on each side of the display rectangle into which the view can render, but which may be partially obscured by system UI (such as the system notification area), or physical intrusions in the display (e.g. overscan regions on television screens or phone sensor housings).
