calculateSize static method

double calculateSize({
  1. required double maxSize,
  2. required Size constraints,
  3. required Axis axis,
  4. required int length,
})

Returns calculated size of a FitWrap with maxSize, constraints, axis and children length.

Implementation

static double calculateSize({
  required double maxSize,
  required Size constraints,
  required Axis axis,
  required int length,
}) {
  var size = min(
    maxSize,
    axis == Axis.horizontal
        ? constraints.height / length
        : constraints.width / length,
  );

  if (axis == Axis.horizontal) {
    if (size * length >= constraints.height) {
      size = constraints.width / 2;
    }
  } else {
    if (size * length >= constraints.width) {
      size = constraints.height / 2;
    }
  }

  return size;
