DatepickerDateRange(String title, Date? start, Date? end, {RangeFn next = _genericNext, RangeFn prev = _genericPrev, bool isPredefined = false, bool isAllTime = false}): factory
DatepickerDateRange.custom(Date? start, Date? end): Shortcut to define a "custom" date range with a localized "Custom" title and default behavior.
factory
DatepickerDateRange.fromProtoBuf(Clock clock, DatepickerDateRange pb): Construct from the protocol buffer format defined in date_range.proto.

end → Date?: no setteroverride
hashCode → int: The hash code for this object.
no setterinherited
isAllTime → bool: true if this date range represents all available history.
no setter
isPredefined → bool: Whether the date range is predefined by the application.
no setter
next → DatepickerDateRange?: A date range which begins immediately after this one ends, and has either the same length or similar semantics (such as "the next month").
no setter
prev → DatepickerDateRange?: A date range which ends immediately before this one starts, and has either the same length or similar semantics (such as "the previous year").
no setter
runtimeType → Type: A representation of the runtime type of the object.
no setterinherited
start → Date?: no setteroverride
title → String: E.g. "Last 7 days", "This month", "Custom", etc.
no setter

asPlainRange() → DateRange: Returns this range as a plain DateRange. This is needed because DateRange's equality is strict on types.
override
clamp({Date? min, Date? max}) → DatepickerDateRange?: Clamps the current date range to the given min and max dates. Returns null if this range has no overlap with the given date range.
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
toProtoBuf() → DatepickerDateRange: Convert this date range into the protocol buffer format defined in date_range.proto.
toString() → String: A string representation of this object.
inherited
unclamped() → DatepickerDateRange: Reverses the effect of one call to clamp() (assuming clamp() didn't return null). If clamp() succeeds, range.clamp(...).unclamped() == range.
