Properties

controller → C
The current day view controller.
final
currentTimeIndicatorBuilder → CurrentTimeIndicatorBuilder?
The current time indicator builder.
final
dragAndDropOptions → DragAndDropOptions?
Configures the behavior for drag-and-drop of events. If this is null (which is the default), drag-and-drop is disabled.
final
hashCode → int
The hash code for this object.
no setterinherited
hoursColumnBackgroundBuilder → HoursColumnBackgroundBuilder?
Building method for building background decoration below single time displayed on the side border.
final
hoursColumnStyle → HoursColumnStyle
The hours column style.
final
hoursColumnTimeBuilder → HoursColumnTimeBuilder?
Building method for building the time displayed on the side border.
final
initialTime → DateTime
The initial visible time. Defaults to the current hour of the day (if possible).
final
inScrollableWidget → bool
Whether the widget should automatically be placed in a scrollable widget.
final
isRTL → bool
Whether the widget should be aligned from right to left.
final
key → Key?
Controls how one widget replaces another widget in the tree.
finalinherited
maximumTime → HourMinute
The maximum time to display.
final
minimumTime → HourMinute
The minimum time to display.
final
onBackgroundTappedDown → BackgroundTapCallback?
Triggered when there's a click on the background (an empty region of the calendar). The returned value corresponds to the hour/minute where the user made the tap. For better user experience, you may want to round this value using roundTimeToFitGrid.
