MultiDayLayoutStrategy class abstract Layout

Assigns each event in the multi-day lane a row and a span of columns.

Columns are the visible dates and rows are the stacking order within the lane. Neither refers to a widget: both are concepts MultiDayLayout uses to position events.

Set it on the header or month body configuration:

MonthBodyConfiguration(
  multiDayLayoutStrategy: const MultiDayLayoutStrategy.byDuration(),
)

Write your own by extending this class. Call defaultMultiDayFrameGenerator from generateFrame to keep the built-in row assignment and change only the order events are placed in, or build the frame yourself.

This is a class rather than a function so that it has value equality. Header and month configurations are compared with == to decide whether the layout frame cache survives, and a function field written inline would clear that cache on every build.
