flutter pub add sliver_calendar基于插件公开信息、社区数据与项目使用情况整理的选型参考。
一个基于滑动条的日历视图 Flutter 包，用于在可滚动且高效的布局中显示日期。专为在自定义滚动视图中使用而设计，支持平滑滚动和动态日期渲染。该包非常适合需要简洁、交互式日历界面且无需大量样板代码的应用程序。通过提供的添加命令，可无缝集成到现有的 Flutter 项目中。

Shows a scrolling calendar list of events. This is still relatively basic, it always assumes that the getEvents returns the entire list of calendar events (mostly ignoring the values passed into the source). It does work however :) Optionally, you can use an image as a background for the calendar header and another image for the month header.
The calendar uses slivers to display the widgets in the view and lets you scroll forward and backward through the events. The header widget will drop down and open up the days of the month, letting you select specific days as well as move back and forth between the months. By default it displays a list of events and not a day view, the day view code is all just a stub right now.
Here is how to use the calendar widget itself:
new CalendarWidget(
initialDate: new TZDateTime.now(local),
buildItem: buildItem,
getEvents: getEvents,
);
How to setup a source for the calendar widget.
...
List<Game> _listToShow;
StreamSubscription<UpdateReason> _listening;
@override
Widget buildItem(BuildContext context, CalendarEvent event) {
return new GameCard(_listToShow[event.index]);
}
@override
List<CalendarEvent> getEvents(DateTime start, DateTime end) {
if (_listToShow == null) {
_listToShow = UserDatabaseData.instance.games.values.toList();
}
if (_listToShow == null) {
return [];
}
List<CalendarEvent> events = new List<CalendarEvent>();
int pos = 0;
_listToShow.forEach((Game g) => events.add(new CalendarEvent(
instant: g.tzTime, instantEnd: g.tzEndTime, index: pos++)));
return events;
}
...
