Methods

clearNeedsPaint() → void
Clears the needs-paint flag, indicating painting is up to date.
inherited
computeChildOffset(Offset parentOffset, Size childSize) → Offset
Offsets the child by the left and top padding.
override
computeSizeFromChild(BoxConstraints constraints, Size childSize) → Size
Expands the child size by adding the padding.
override
computeSizeWithoutChild(BoxConstraints constraints) → Size
Returns the size when there is no child (just the padding dimensions).
override
getConstraintsForChild(BoxConstraints constraints) → BoxConstraints
Deflates the incoming constraints by the padding amount.
override
layout(Constraints constraints, {bool parentUsesSize = true}) → void
Performs layout on this render object using the given constraints.
inherited
markNeedsLayout() → void
Marks this render object as needing layout and paint.
inherited
markNeedsPaint() → void
Marks this render object as needing to be repainted.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
paint(PaintingContext context, Offset offset) → void
Paints this render object into the given context at offset.
inherited
performLayout(Constraints constraints) → void
Called to perform the actual layout computation for this render object.
inherited
setRelayoutBoundary(bool value) → void
Marks this render object as a relayout boundary or not.
inherited
setupParentData(RenderObject child) → void
Initializes parentData for the given child if not already set.
inherited
toString() → String
A string representation of this object.
