removeDisplayFeatures method
- Rect subScreen
Creates a copy of this media query data by removing displayFeatures that are completely outside the given sub-screen and adjusting the padding, viewInsets and viewPadding to be zero on the sides that are not included in the sub-screen.
Returns unmodified MediaQueryData if the sub-screen coincides with the available screen space.
Asserts in debug mode, if the given sub-screen is outside the available screen space.
See also:
- DisplayFeatureSubScreen, which removes the display features that split the screen, from the MediaQuery and adds a Padding widget to position the child to match the selected sub-screen.
Implementation
MediaQueryData removeDisplayFeatures(Rect subScreen) {
assert(subScreen.left >= 0.0 && subScreen.top >= 0.0 &&
subScreen.right <= size.width && subScreen.bottom <= size.height,
"'subScreen' argument cannot be outside the bounds of the screen");
if (subScreen.size == size && subScreen.topLeft == Offset.zero) {
return this;
}
final double rightInset = size.width - subScreen.right;
final double bottomInset = size.height - subScreen.bottom;
