Is your feature request related to a problem? Please describe. The problem is in the beginning because users must go in the selected date when the DatePicker has appeared and for the moment we only can go in the selected date after we use _controller.jumpToSelection(); in DatePicker View.

Describe the solution you'd like Maybe we can call _controller.jumpToSelection() in initState

I have the calendar selector in a simple Container, on iOS is fits perfect, on Android Pixel 3 Simulator, the width is too small

@override
  Widget build(BuildContext context) {

    return Container(
      height:90,
      decoration: BoxDecoration(
        color: Colors.white,
      ),
      padding: const EdgeInsets.only(top: 4, bottom:5, left: 10, right: 10),

      child: DatePickerTimeline(
        _currentSelection,
        dateSize: 20,
        daySize: 10,
        monthSize: 10,
        selectionColor: Colors.grey[200],
        monthColor: Colors.grey[500],
        onDateChange: (date) {
          _selectDate(date);
        },
      )
    );
  }

Expected behavior

Between both devices I expected the same edge to edge layout,. It doesnt seem to be inheriting font styles on Android either (right screen)

Is your feature request related to a problem? Please describe. I am wanting to use this fantastic widget to select dates from the past. At present it seems to only work for future dates.

Describe the solution you'd like Perhaps you could add a stateDate parameter that is set to today by default.

Describe alternatives you've considered Fork the code and add the feature.

Additional context

Apparently, you can scrolll to the left by simply replacing ListView by InfiniteListView (Issue #10), which comes from another package called infinite_listview.

I think you will need to add the infinite_listview to the pubspec.yaml file (PR #13), but I'm not sure — I'm not experienced with putting packages inside packages.

I would suggest testing if this does fill all of the requirements. Perhaps putting it into another branch might be more appropriate.

Hey guys,

first we really enjoy your work and love the datepicker timeline.

We are searching for a feature to jump to a specific date. Example: timeline is on 01.01.2020, users press a button with "12.12.2020" and the timeline jumps to this date immediately.

Do you have any idea or implementation for this? Would be very helpful for lots of users we think.

Thanks for your attention.

Describe the bug

the JumpToSelection() function takes the time into consideration causing offset values to change during different times.

To Reproduce

Create a startDate to be of the format "YYYY-MM-DD 00:00:00" select initialSelectedDate as DateTime.now() over the course of the day, on calling the JumpToSelection() for the first time via a separate button, the timeline will jump from to the date +1 value ( ex: if today is may 11th, JumpToSelection() will jump to May 12th after a period of the day has passed)

Expected behavior

A clear and concise description of what you expected to happen. on initial jump, the timeline should jump to the initialSelectedDate Value

Is your feature request related to a problem? Please describe. Yes, I need to set min & max dates to show in the list, not confused with currentDate. For example, I want today must be the max date, thus user can only scroll to past dates and prevent user from selecting future dates.

Describe the solution you'd like Please add minDate and maxdate in the constructor as optional.

Describe alternatives you've considered Or maybe as an alternative also add type with value "future" (calendar will show current & future dates) or "past" (calendar will show current & past dates).

Additional context Nothing.

DateTime _currentSelection = new DateTime.now().add(Duration(days: 2))

DatePickerTimeline(
        _currentSelection,
        dateSize: 20,
        daySize: 10,
        monthSize: 10,
        selectionColor: Colors.grey[200],

        onDateChange: (date) {
          _selectDate(date);
        },
      )

Selector does not change, it stays on today

Is your feature request related to a problem? Please describe.

I want to ask if the package has the feature where we can have a button to automatically slide back straight to today's date after sliding to some date far away from today's one.

Describe the solution you'd like

If the feature does not exist, please I am requesting to add it.

Describe alternatives you've considered

If the proposed feature is not worth to be implemented, I would like to get some tips on how I can do it myself with my custom methods without altering the package.

Additional context

Describe the bug

Whenever the user changes the calendar date, something should happen in my program. At least a class I created to store my screen's data should change. In order to do so, I'm calling a method that changes the internal data and then calling notifyListeners() to update other fields. However, if I use notifyListeners(), the selected date on the calendar doesn't change; the data does change, but not the selected rectangle on the screen.

To Reproduce

The code in my app is quite long, but I believe the following should suffice...

The DatePickerTimeline call:

DatePickerTimeline(
  DateTime.now(),
  onDateChange: (newDate){
    data.changeDay(date: newDate);
  }

The method to update the data is something like:

void changeDay({DateTime date}){
  this.day = date;
  notifyListeners();
}

Expected behavior

Why is the selected rectangle not being selected? I've also tried to refactor the code to use the Provider package instead of setState() but it didn't work either.

Desktop (please complete the following information):

• OS: Windows 10
• Browser: Firefox

Smartphone (please complete the following information):

• Device: Nexus 6
• OS: Android 9.0

Now if someone wants to display dates in reverse order, it could be done just by adding one argument

DatePicker(
   // rest of code
  reverseDays: true,
)

Is your feature request related to a problem? Please describe. I want to focus center when date clicked and focus initialSelectedDate when entered page.

If the parent widget rebuilds , the framework will update the [widget] property of this [State] object to refer to the new widget and then call this method with the previous widget as an argument.

Override this method to respond when the [widget] changes.

The framework always calls [build] after calling [didUpdateWidget], which means setState not required in thi function.

I used this function update current date if it's change and animate to this date.

Allow hiding date widgets if that date is deactivated by wrapping your DateWidget in a Visibility widget. Let the user pass a boolean to decide if hiding or not.
