firstDayOfWeekIndex property
override
Index of the first day of week, where 0 points to Sunday, and 6 points to Saturday.
This getter is compatible with narrowWeekdays. For example:
var localizations = MaterialLocalizations.of(context);
// The name of the first day of week for the current locale.
var firstDayOfWeek = localizations.narrowWeekdays[localizations.firstDayOfWeekIndex];
Implementation
@override
int get firstDayOfWeekIndex => (_longDateFormat.dateSymbols.FIRSTDAYOFWEEK + 1) % 7;
