NotebookStyle class
An immutable description of notebook ruling and margins: how the hand-drawn rules look, how far apart they sit, and where content may be written between the page edges.
A NotebookStyle carries these values only. It performs no painting, layout, or widget building — it exists to bundle the values, validate them, and support comparison and overriding via copyWith and value equality.
lineHeight is the row height: the vertical distance from one rule to the next, and the unit content is laid onto. leadingMargin and trailingMargin bound where content is written on each row; the rules are unaffected by them and span the full width beneath. Every other property describes the appearance of the hand-drawn rules.
const style = NotebookStyle(lineHeight: 32, leadingMargin: 24);
final bolder = style.copyWith(strokeWidth: 2.0);
