createViewConfiguration method
- @override
override
Returns a ViewConfiguration configured for the RenderView based on the current environment.
This is called during construction and also in response to changes to the system metrics.
Bindings can override this method to change what size or device pixel
ratio the RenderView will use. For example, the testing framework uses
this to force the display into 800x600 when a test is run on the device
using flutter run.
Implementation
@override
ViewConfiguration createViewConfiguration() {
final double devicePixelRatio = ui.window.devicePixelRatio;
final Size size = _surfaceSize ?? ui.window.physicalSize / devicePixelRatio;
return ViewConfiguration(
size: size,
devicePixelRatio: devicePixelRatio,
);
}
