getConstraintsForChild method

@override BoxConstraints getConstraintsForChild(BoxConstraints constraints)

The constraints for the child given the incoming constraints.

During layout, the child is given the layout constraints returned by this function. The child is required to pick a size for itself that satisfies these constraints.

Defaults to the given constraints.

Implementation

@override
// BoxConstraints getConstraintsForChild(BoxConstraints constraints) =>  constraints.loosen();
// BoxConstraints getConstraintsForChild(BoxConstraints constraints) => BoxConstraints(maxWidth: _anchorSize.width, maxHeight: _anchorSize.height, minHeight: 64);
BoxConstraints getConstraintsForChild(BoxConstraints constraints) {
  // Pass constraints with width from _size, and min/max height - child will size itself within these bounds
  return BoxConstraints(
    minWidth: _size.value.width,
    maxWidth: _size.value.width,
    minHeight: minHeight,
    maxHeight: maxHeight,
  );
}
