What's new? #

Add new widget called: EasyInfiniteDateTimeLine , It allows you to define a range of dates with firstDate and lastDate, specify the initial focus with focusedDate, and offers a controller for programmatic interactions:

controller: The Controller parameter is an optional controller that allows you to manage and interact with the InfiniteTimeLineWidget. You can use this controller to programmatically manipulate the widget's behavior. For example, you can scroll to specific dates, control animations, or perform other actions within the timeline. This controller is a powerful tool for integrating the widget with your app's logic.
firstDate: This required parameter specifies the start date of the timeline. It defines the earliest date that will be displayed in the timeline view. You should set this date to the beginning of the time range you want to visualize.
lastDate: This required parameter defines the end date of the timeline. It determines the latest date that will be visible within the timeline. Typically, this date should be set to represent the end of the time range you want to display.
focusedDate: Another required parameter, the focusedDate determines which date is currently in focus within the timeline.

Dynamic Text Color : The "easy_date_timeline" package automatically adjusts the text color of the active day based on the active color.

This ensures that the text is always easy to read and contrasts well with the background color.

IMPORTANT NOTE:
When utilizing the itemBuilder, it is essential to provide the width of each day for the date timeline widget.
For example:

dayProps: const EasyDayProps(
// You must specify the width in this case.
width: 124.0,
),

EasyInfiniteDateTimeLine itemBuilder example: #
You can use the itemBuilder to customize the appearance of the day widget.
The itemBuilder provides the following:

BuildContext context: The context of the widget.
DateTime date: The date of the day widget.
bool isSelected: Whether the day widget is selected or not.
VoidCallback onTap: The callback that triggers when the day widget is tapped.




return EasyInfiniteDateTimeLine(
selectionMode: const SelectionMode.autoCenter(),
firstDate: DateTime(2024),
focusDate: _focusDate,
lastDate: DateTime(2024, 12, 31),
onDateChange: (selectedDate) {
setState(() {
_focusDate = selectedDate;
});
},
dayProps: const EasyDayProps(
// You must specify the width in this case.
width: 64.0,
// The height is not required in this case.
height: 64.0,
),
itemBuilder: (
BuildContext context,
DateTime date,
bool isSelected,
VoidCallback onTap,
) {
return InkResponse(
// You can use `InkResponse` to make your widget clickable.
// The `onTap` callback responsible for triggering the `onDateChange`
// callback and animating to the selected date if the `selectionMode` is
// SelectionMode.autoCenter() or SelectionMode.alwaysFirst().
onTap: onTap,
child: CircleAvatar(
// use `isSelected` to specify whether the widget is selected or not.
backgroundColor:
isSelected ? fillColor : fillColor.withOpacity(0.1),
radius: 32.0,
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: [
Flexible(
child: Text(
date.day.toString(),
style: TextStyle(
color: isSelected ? Colors.white : null,
),
),
),
Flexible(
child: Text(
EasyDateFormatter.shortDayName(date, "en_US"),
style: TextStyle(
color: isSelected ? Colors.white : null,
),
),
),
],

Custom background #
Use the activeDayProps in dayProps that contains decoration
for the active day.



EasyDateTimeLine(
initialDate: DateTime.now(),
onDateChange: (selectedDate) {
//`selectedDate` the new date selected.
},
headerProps: const EasyHeaderProps(
monthPickerType: MonthPickerType.switcher,
dateFormatter: DateFormatter.fullDateDMY(),
),
dayProps: const EasyDayProps(
dayStructure: DayStructure.dayStrDayNum,
activeDayStyle: DayStyle(
decoration: BoxDecoration(
borderRadius: BorderRadius.all(Radius.circular(8)),
gradient: LinearGradient(
begin: Alignment.topCenter,
end: Alignment.bottomCenter,
colors: [
Color(0xff3371FF),
Color(0xff8426D6),
