WeekNumberWidthBuilder typedef Appearance
WeekNumberWidthBuilder =
double Function(BuildContext context)
The width of the month's week number column.
The column is drawn in the month body and reserved again in the month header, so both read one number rather than each measuring what they build. It is not called for a view that draws no week numbers.
It runs above KalenderHeader and KalenderBody, so the context resolves
KalenderTheme and every KalenderScope accessor except the four those two
install: interactionOf, snappingOf, tileComponentsOf and
heightPerMinuteOf.
Implementation
typedef WeekNumberWidthBuilder = double Function(BuildContext context);
