All of the arguments must not be null and must not be negative. The
crossAxisCount
argument must be greater than zero.
Implementation
const SliverGridRegularTileLayout({
@required this.crossAxisCount,
@required this.mainAxisStride,
@required this.crossAxisStride,
@required this.childMainAxisExtent,
@required this.childCrossAxisExtent,
@required this.reverseCrossAxis,
}) : assert(crossAxisCount != null && crossAxisCount > 0),
assert(mainAxisStride != null && mainAxisStride >= 0),
assert(crossAxisStride != null && crossAxisStride >= 0),
assert(childMainAxisExtent != null && childMainAxisExtent >= 0),
assert(childCrossAxisExtent != null && childCrossAxisExtent >= 0),
assert(reverseCrossAxis != null);
