performLayout method

  1. @override
Size performLayout(
  1. BoxConstraints constraints
)
override

Hook for subclasses to perform layout within the given constraints.

Implementation

@override
Size performLayout(BoxConstraints constraints) {
  final w = constraints.maxWidth == BoxConstraints.infinity
      ? 10
      : constraints.maxWidth;
  final h = constraints.maxHeight == BoxConstraints.infinity
      ? 2
      : constraints.maxHeight;
  return constraints.constrain(Size(w, h));
}
