Divider class

A filled rule that separates sections of a layout.

The rule is a solid band of thickness cells, not a run of ─: a band needs no width to be known up front, so the divider stays pure composition and inherits whatever cross-axis extent its parent offers.

It spans as much of its cross axis as the parent offers, so that axis has to be bounded. A horizontal rule in a Column is bounded by the terminal width and needs nothing extra:

Column(children: [header, const Divider(), body])

A vertical rule inside a Row is a different story: a Row hands its children an unbounded height whenever its own parent leaves the height loose, and an unbounded axis has no extent to span, so the rule renders zero cells tall. Give it a height:

Row(
  children: [
    left,
    const SizedBox(height: 3, child: Divider(axis: Axis.vertical)),
    right,
  ],
)

key → Key?
Controls how this widget replaces another of the same type.

runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
thickness → int
Cells of extent the rule occupies along its short side.
