TestViewConfiguration class
A ViewConfiguration that pretends the display is of a particular size (in logical pixels).
The resulting ViewConfiguration maps the given size onto the actual display using the BoxFit.contain algorithm.
If the underlying FlutterView changes, a new TestViewConfiguration should be created. See RendererBinding.handleMetricsChanged and RendererBinding.createViewConfigurationFor.

Constructors
- TestViewConfiguration({Size size = _kDefaultTestViewportSize, FlutterView? window})
-
Deprecated. Will be removed in a future version of Flutter.
factory
- TestViewConfiguration.fromView({required FlutterView view, Size size = _kDefaultTestViewportSize})
- Creates a TestViewConfiguration with the given size and view.
