<itemvalue="Convert the given point from the local coordinate system for this box to the global coordinate system in logical pixels. If `ancestor` is non-null, this function converts the given point to the coordinate system of `ancestor` (which must be an ancestor of this render object) instead of to the global coordinate system. This method is implemented in terms of [getTransformTo]. If the transform matrix puts the given `point` on the line at infinity (for instance, when the transform matrix is the zero matrix), this method returns (NaN, NaN)."/>
<itemvalue="Vertical viewport was given unbounded height. Viewports expand in the scrolling direction to fill their container. In this case, a vertical viewport was given an unlimited amount of vertical space in which to expand. This situation typically happens when a scrollable widget is nested inside another scrollable widget. If this widget is always nested in a scrollable widget there is no need to use a viewport because there will always be enough vertical space for the children. In this case, consider using a Column instead. Otherwise, consider using the "shrinkWrap" property (or a ShrinkWrappingViewport) to size the height of the viewport to the sum of the heights of its children."/>

<itemvalue="RenderBox.size accessed beyond the scope of resize, layout, or permitted parent access. RenderBox can always access its own size, otherwise, the only object that is allowed to read RenderBox.size is its parent, if they have said they will.
