minSelectableDate property
Sets the minimum day within the selectable month range.
Every day before the chosen day is flagged as outside of the range. All days between the minimum and maximum days are considered in range. The selected day must fall within the range defined by disablePreviousMonthFromDate and disableNextMonthFromDate. If minSelectableDate is explicitly set but falls outside the allowable month range, it will be limited to the disablePreviousMonthFromDate or its default.
Implementation
final DateTime? minSelectableDate;
