DatePickerTimeline 
A linear Android date picker library written in Jetpack compose.
Inspired by https://pub.dev/packages/date_picker_timeline
Installation 
Add the dependency to your build.gradle or build.gradle.kts file
repositories {
maven { url 'https://jitpack.io' }
}
dependencies{
implementation ("com.github.Rafsanjani:datepickertimeline:<latest_version>")
}Usage
For a horizontal date picker with no customization
DatePickerTimeLine(
modifier = Modifier,
onDateSelected = {selectedDate: LocalDate->
//do something with selected date
}
) For a vertical date picker with no customization
import com.foreverrafs.datepicker.Orientation
DatePickerTimeLine(
modifier = Modifier,
orientation = Orientation.Vertical,
onDateSelected = {selectedDate: LocalDate->
//do something with selected date
}
) You can pass an optional state to the picker and specify the initial selected date
DatePickerTimeLine(
modifier = Modifier,
state = rememberDatePickerState(initialDate = LocalDate.now()),
onDateSelected = { selectedDate: LocalDate ->
//do something with selected date
}
) To customize the full list of properties
import com.foreverrafs.datepicker.Orientation
val today = LocalDate.now()
val datePickerState =
rememberDatePickerState(initialDate = LocalDate.now())
DatePickerTimeline(
modifier = Modifier.wrapContentSize(),
onDateSelected = { selectedDate: LocalDate ->
// do something with the selected date
},
backgroundColor = Color.Yellow, // the main background color
state = datePickerState,
orientation = Orientation.Horizontal,
selectedBackgroundColor = Color.Green, // The background of the currently selected date
selectedTextColor = Color.White, // Text color of currently selected date
dateTextColor = Color.Black, //Text color of all dates
eventDates = listOf(
today.plusDays(1),
today.plusDays(3),
today.plusDays(5),
today.plusDays(8),
),
todayLabel = {
Text(
modifier = Modifier.padding(10.dp),
text = "Today",
color = Color.White,
style = MaterialTheme.typography.h6
)
},
pastDaysCount = 10, // The number of previous dates to display, relative to the initial date. Defaults to 120
eventIndicatorColor = Color.Brown // Indicator color for marked event dates.
)Scrolling to different dates
You can store the DatePickerState object into a variable and use it to perform smooth scrolling to any date. This is very similar to how LazyListState works. If you try to scroll to an invalid date as constrained by the pastDaysCount property, you are scrolled to the first valid date in the calendar instead.
val today = LocalDate.now()
val datePickerState =
rememberDatePickerState(initialDate = LocalDate.now())
Column{
DatePickerTimeline(
state = datePickerState
)
Button(
onClick = {
// Scroll to Jan 01, 2022
datePickerState.smoothScrollTodate(LocalDate.of(2022, 1, 1)
}
){
Text("Go to different date")
}
