+## 主要功能
+* 支持公历，农历，节气，传统节日，常用节假日
+* 日期范围设置，默认支持的最大日期范围为1971.01-2055.12
+* 禁用日期范围设置，比如想实现某范围的日期内可以点击，范围外的日期置灰
+* 支持单选、多选模式，提供多选超过限制个数的回调和多选超过指定范围的回调。
+* 跳转到指定日期，默认支持动画切换
+* 自定义日历Item，支持组合widget的方式和利用canvas绘制的方式
+* 自定义顶部的WeekBar
+* 可以给Item添加自定义的额外数据，实现各种额外的功能。比如实现进度条风格的日历
+
+## 使用
+引入flutter_custom_calendar,就可以使用CalendarViewWidget，配置CalendarController就可以了。
+```
+CalendarViewWidget({@required this.calendarController, this.boxDecoration});
+```
+* boxDecoration用来配置整体的背景
+* 利用CalendarController来配置一些数据，并且可以通过CalendarController进行一些操作或者事件监听，比如滚动到下一个月，获取当前被选中的Item等等。
+
+下面是CalendarController中一些支持自定义配置的属性。不配置的话，会有对应的默认值。
+```
+//默认是单选,可以配置为MODE_SINGLE_SELECT，MODE_MULTI_SELECT
+int selectMode;
+
+//日历显示的最小年份和最大年份
+int minYear;
+int maxYear;
+
+//日历显示的最小年份的月份，最大年份的月份
+int minYearMonth;
+int maxYearMonth;
+
+//日历显示的当前的年份和月份
+int nowYear;
+int nowMonth;
+
+//可操作的范围设置,比如点击选择
+int minSelectYear;
+int minSelectMonth;
+int minSelectDay;
+
+int maxSelectYear;
+int maxSelectMonth;
+int maxSelectDay; //注意：不能超过对应月份的总天数
+
+Set selectedDateList = new Set(); //被选中的日期,用于多选
+DateModel selectDateModel; //当前选择项,用于单选
+int maxMultiSelectCount; //多选，最多选多少个
+Map extraDataMap = new Map(); //自定义额外的数据
+
+//各种事件回调
+OnMonthChange monthChange; //月份切换事件
+OnCalendarSelect calendarSelect; //点击选择事件
+OnMultiSelectOutOfRange multiSelectOutOfRange; //多选超出指定范围
+OnMultiSelectOutOfSize multiSelectOutOfSize; //多选超出限制个数
+
+//支持自定义绘制
+DayWidgetBuilder dayWidgetBuilder; //创建日历item
+WeekBarItemWidgetBuilder weekBarItemWidgetBuilder; //创建顶部的weekbar
+```
+
+### 利用controller添加监听事件
+比如月份切换事件、点击选择事件。
+```
+//月份切换监听
+void addMonthChangeListener(OnMonthChange listener) {
+ this.monthChange = listener;
+}
+//点击选择监听
+void addOnCalendarSelectListener(OnCalendarSelect listener) {
+ this.calendarSelect = listener;
+}
+//多选超出指定范围
+void addOnMultiSelectOutOfRangeListener(OnMultiSelectOutOfRange listener) {
+ this.multiSelectOutOfRange = listener;
+}
+//多选超出限制个数
+void addOnMultiSelectOutOfSizeListener(OnMultiSelectOutOfSize listener) {
+ this.multiSelectOutOfSize = listener;
+}
+```
+
+### 利用controller来控制日历的切换，支持配置动画
+
+```
+//跳转到指定日期
+void moveToCalendar(int year, int month, int day,
+ {bool needAnimation = false,
+ Duration duration = const Duration(milliseconds: 500),
+ Curve curve = Curves.ease});
+//切换到下一年
+void moveToNextYear();
+//切换到上一年
+void moveToPreviousYear();
+//切换到下一个月份,
+void moveToNextMonth();
+//切换到上一个月份
+void moveToPreviousMonth();
+```
+
+### 利用controller来获取日历的一些数据信息
+```
+// 获取当前的月份
+DateTime getCurrentMonth();
+//获取被选中的日期,多选
+Set getMultiSelectCalendar();
+//获取被选中的日期，单选
+DateModel getSingleSelectCalendar();
+```
+
+### 自定义UI
+
+包括自定义WeekBar、自定义日历Item，默认使用的都是DefaultXXXWidget。
+
+只要继承对应的Base类，实现相应的方法，然后只需要在配置Controller的时候，实现相应的Builder方法就可以了。
+```
+//支持自定义绘制
+DayWidgetBuilder dayWidgetBuilder; //创建日历item
+WeekBarItemWidgetBuilder weekBarItemWidgetBuilder; //创建顶部的weekbar
+```
+### 自定义WeekBar
+继承BaseWeekBar，重写getWeekBarItem(index)方法就可以。随便你怎么实现，只需要返回一个Widget就可以了。
+```
+class DefaultWeekBar extends BaseWeekBar {
+ const DefaultWeekBar({Key key}) : super(key: key);
+ @override
+ Widget getWeekBarItem(int index) {
+ /**
+ * 自定义Widget
+ */
+ return new Container(
+ height: 40,
+ alignment: Alignment.center,
+ child: new Text(
+ Constants.WEEK_LIST[index],
+ style: topWeekTextStyle,
+ ),
+ );
+ }
+}
+```
+### 自定义日历Item：
+提供两种方法，一种是利用组合widget的方式来创建，一种是利用Canvas来自定义绘制Item。最后只需要在CalendarController的构造参数中进行配置就可以了。
+* 继承BaseCombineDayWidget，重写getNormalWidget(DateModel dateModel)
+和getSelectedWidget(DateModel dateModel)就可以了，返回对应的widget就行。
+```
+class DefaultCombineDayWidget extends BaseCombineDayWidget {
+ DefaultCombineDayWidget(DateModel dateModel) : super(dateModel);
+
+ @override
+ Widget getNormalWidget(DateModel dateModel) {
+ //实现默认状态下的UI
+ }
+
+ @override
+ Widget getSelectedWidget(DateModel dateModel) {
+ //绘制被选中的UI
+ }
+}
+```
+* 继承BaseCustomDayWidget，重写drawNormal和drawSelected的两个方法就可以了，利用canvas自己绘制Item。
+```
+class DefaultCustomDayWidget extends BaseCustomDayWidget {
+ DefaultCustomDayWidget(DateModel dateModel) : super(dateModel);
+ @override
+ void drawNormal(DateModel dateModel, Canvas canvas, Size size) {
+ //实现默认状态下的UI
+ defaultDrawNormal(dateModel, canvas, size);
+ }
+ @override
+ void drawSelected(DateModel dateModel, Canvas canvas, Size size) {
+ //绘制被选中的UI
+ defaultDrawSelected(dateModel, canvas, size);
+ }
+}
+```
+### DateModel实体类
+日历所用的日期的实体类DateModel，有下面这些属性。
+```
+/**
+ * 日期的实体类
+ */
+class DateModel {
+ int year;
+ int month;
+ int day = 1;
+ int lunarYear;
+ int lunarMonth;
+ int lunarDay;
+ String lunarString; //农历字符串
+ String solarTerm; //24节气
+ String gregorianFestival; //公历节日
+ String traditionFestival; //传统农历节日
+ bool isCurrentDay; //是否是今天
+ bool isLeapYear; //是否是闰年
+ bool isWeekend; //是否是周末
+ int leapMonth; //是否是闰月
+ Object extraData; //自定义的额外数据
+ bool isInRange = false; //是否在范围内,比如可以实现在某个范围外，设置置灰的功能
+ bool isSelected; //是否被选中，用来实现一些标记或者选择功能
+ @override
+ String toString() {
+ return 'DateModel{year: $year, month: $month, day: $day}';
+ } //如果是闰月，则返回闰月
+
+ //转化成DateTime格式
+ DateTime getDateTime() {
+ return new DateTime(year, month, day);
+ }
+ //根据DateTime创建对应的model，并初始化农历和传统节日等信息
+ static DateModel fromDateTime(DateTime dateTime) {
+ DateModel dateModel = new DateModel()
+ ..year = dateTime.year
+ ..month = dateTime.month
+ ..day = dateTime.day;
+ LunarUtil.setupLunarCalendar(dateModel);
+ return dateModel;
+ }
+ @override
+ bool operator ==(Object other) =>
+ identical(this, other) ||
+ other is DateModel &&
+ runtimeType == other.runtimeType &&
+ year == other.year &&
+ month == other.month &&
+ day == other.day;
+ @override
+ int get hashCode => year.hashCode ^ month.hashCode ^ day.hashCode;
+}
+```
+
+## TODO LIST
+* 优化代码实现
+* 支持屏蔽指定的某些天
+* 继续写几个不同风格的Demo
+* 支持周视图
+* 支持动画切换周视图和月视图

+ # To add assets to your package, add an assets section, like this:
+ # assets:
+ # - images/a_dot_burr.jpeg
+ # - images/a_dot_ham.jpeg
+ #
+ # For details regarding assets in packages, see
+ # https://flutter.dev/assets-and-images/#from-packages
+ #
+ # An image asset can refer to one or more resolution-specific "variants", see
+ # https://flutter.dev/assets-and-images/#resolution-aware.
+
+ # To add custom fonts to your package, add a fonts section here,
+ # in this "flutter" section. Each entry in this list should have a
+ # "family" key with the font family name, and a "fonts" key with a
+ # list giving the asset and other descriptors for the font. For
+ # example:
+ # fonts:
+ # - family: Schyler
+ # fonts:
+ # - asset: fonts/Schyler-Regular.ttf
+ # - asset: fonts/Schyler-Italic.ttf
+ # style: italic
+ # - family: Trajan Pro
+ # fonts:
+ # - asset: fonts/TrajanPro.ttf
+ # - asset: fonts/TrajanPro_Bold.ttf
+ # weight: 700
