The month label describing the visible month days does not get updated correctly when switching between months.

I am not able to run the example application because it has errors. Is this an issue that others have?

I really like the look of the calendar.
For a pet project I would like to decorate the default dayBuilder.
This is quite hard, as the CalendarTiles need local information of the iterating over the calendar dates.

Hello,

Is it normal that when swiping the selected date indicator even if the user doesn't tap on a specific date ?

How to prevent this behavior ? I would like to highlight the user's selection only.
Indeed, if the user swipe, he might think that he lost his selected date or that I changed his selection.
Moreover, if the user swipe and see that the indicator (highlighted day) change, he won't feel necessary (or weird) to select the day he thinks has been selected when swiping. Users will definitively think it's a bug.

I hope I explain myself well, english isn't my native language.
If you need further explanation, I'll be glad to provide them.

Thanks

This plugin is good for showing calendar in our apps but there are some issues occurred in expanded mode as it is working properly in week mode/ collapsed.
In expanded mode, some months are skipped by this calendar and repeat the very next month.
So this is not very much stable.

Please provide us some solution!!

How to fix this issue.

flutter_calendar >=0.0.3 depends on date_utils <0.1.0 which requires SDK version >=1.20.1 <2.0.0, flutter_calendar >=0.0.3 is forbidden.
So, because flutter_calendar <0.0.3 requires SDK version >=1.8.0 <2.0.0 and word_memorize depends on flutter_calendar any, version solving failed.
pub finished with exit code 1

Hi, I'm using the master channel on flutter (SDK 2.1), and when I run flutter packages get I receive the following error:

Because flutter_calendar 0.0.4 depends on date_utils any which requires SDK version >=1.20.1 <2.0.0, flutter_calendar 0.0.4 is forbidden. 

I've forked your projects (date_utils and flutter_calendar), changed the sdk requirement from <2.0.0 to <3.0.0 and apparently it still works good. I'm just not sure if I've made all necessary tests, do perhaps you could run the tests and update the package?

Thanks.

It's possible to start the week at monday ?
In european's country, our calendar start on Monday and not on Sunday.

Should be nice to be able to customise:

• background color
• text color
• day selection color

Going to the next or previous month is not updated correctly when the first day of the week is still in the previous month.

void nextMonth() { setState(() { today = Utils.nextMonth(today); final firstDateOfNewMonth = Utils.firstDayOfMonth(today); final lastDateOfNewMonth = Utils.lastDayOfMonth(today); updateSelectedRange(firstDateOfNewMonth, lastDateOfNewMonth); selectedMonthsDays = Utils.daysInMonth(today); displayMonth = Utils.formatMonth(Utils.firstDayOfWeek(today)); }); }

It is an easy fix, instead of getting the first day of the week, you just get the month of the current day. This should be in the correct month already.

void nextMonth() { setState(() { today = Utils.nextMonth(today); final firstDateOfNewMonth = Utils.firstDayOfMonth(today); final lastDateOfNewMonth = Utils.lastDayOfMonth(today); updateSelectedRange(firstDateOfNewMonth, lastDateOfNewMonth); selectedMonthsDays = Utils.daysInMonth(today); displayMonth = Utils.formatMonth(today); }); }

Hey great work there! I have a note to make:

If you provide a dayBuilder then the standard functionality inside function handleSelectedDateAndUserCallback is overriden and this is not a good thing because it handles crucial data for the widget. I resolved it by providing an Inkwell as dayBuilder that triggers function handleSelectedDateAndUserCallback.

But before this I had to

1. Alter the constructor of the Calendar to accept a Key key
2. Rename _CalendarState to CalendarState
3. Save a final calendarKey = new GlobalKey(); in my widget
4. Construct a new Calendar providing the above GlobalKey
5. Set the dayBuilder param of Calendar to an Inkwell with onTap functionality like this:
   onTap: () {
   _setTheDate(day); // my functionality for my page
   calendarKey.currentState.handleSelectedDateAndUserCallback(day);
   }

That's it, now the selectedWeeksDays of the calendar get updated and when it is not expanded the selected week stays in focus!

This is more like a question, since I need to be able to display the first day of the week as a Monday instead of Sunday, and then the last day of the week will become Sunday. Is there a way to do this at the moment? Or does this need adjustments

When you click on the calendar button it shows the calendar picker as it should but then if you click cancel the app crashes

"The getter year was called with null"

This is due to lines 314 & 315 referring to a date that is null in flutter_calendar.dart. Moving these inside the if statement will fix the issue

Do you need a PR or can you make the change?

Good day,

When changing the range with the left / right buttons the datarange updates correctly, but, when you. are on a month and choose to expand the calendar, the onSelectedRangeChange is not being called. The range do however get updated with the correct values when you continue left / right in expanded state.

It would be great if the onSelectedRangeChange gets called when the calendar is expanded / minimized.

Are there any plans to add support to select multiple days?

After the first day is selected the next selection will mark an additional day. The distance between the days should be marked with primaryColor.

Image:

I cannot make the get as it looks like date utils is incompatible, can you please fix?

My pubspec:

environment:
  sdk: ">=2.0.0 <3.0.0"


dependencies:
  flutter:
    sdk: flutter
  flutter_localizations:
    sdk: flutter


  # The following adds the Cupertino Icons font to your application.
  # Use with the CupertinoIcons class for iOS style icons.
  cupertino_icons: ^0.1.0
  date_utils: ^0.1.0
  tuple: ^1.0.1
  flutter_calendar: "^0.0.4"

Does the calendar support languages other than english? Is the some "locale" method that i can place the user's location and the calendar would display the according language.

Not a bug, but it would be great if the library included more useful methods such as onWeekChange and onMonthChange.

Only Thing here that needs a change is the day of the week names. This only happens when the theme of the material app has brightness set to dark.

You have one issue with the april 2019. The month starts at Monday but your Widget shows it as Tuesday (image attached).
I investigated the code and found that Utils.daysInMonth returns one more day (it is the bug in their code because the method is not aware of TimeZone). You expect that daysInMonth should return list with Sunday as the first element but this method returned Saturday as the first day in the array.

Anyone had a need for this yet?

Hello,

I've found a bug : when I swipe on the Calendar and tap on the expand icon,
the highlighted day is lost.

If your calendar is not expanded, you need to swipe until the month changes otherwise you won't see the bug.

Thanks

How can I use locale?

So, because siyou depends on both easy_localization ^1.3.1 and flutter calendar ^0.0.8, version solving failed
Because every version of easy localization depends on flutter_localizations any from sdk which depends on intl 0.16.0, every version of easy localization requires intl 0.16.0. So, because siyou depends on both intl ^0.15.8 and easy_localization ^1.3.1, version solving failed.

To reproduce:
Expand the calendar
Navigate with chevron to a month where the amount of rows is less than current month
Click date on last row
Deflate calendar (un-expand?)
Calendar is no longer expandable

When press today button on expanded calendar, does not move to current month.
Please add the following to resetToToday().

selectedMonthsDays = Utils.daysInMonth(_selectedDate);

The calendar shows me two consecutive July months. Have you encountered this problem?

I've managed to change Weekdays name,
how can i put monday as first day?
and how can i replace Months name so that they are italians? switching to italian language doesn't work

How to start expanded?
I want to use isExpandable: false, and start with the calendar expanded, I can easily change line 44 from flutter_calendar from
bool isExpanded = false;
to
bool isExpanded = true;
But it will work until next update...
Any idea?
Can I add an constructor and commit it too?
Thanks

Hello, nice widget.
But it lacks a bit of customisable options.

It would be awesome to be able to specify the expended state with something like isExpanded.
Benefits :

• can be used both with isExpandable set to true or false.
• can set the initial state of the widget
  IMHO the isExpandable should just add the possibility to display the expendable icon and give to users the possibility to expand or note the calendar widget.

Another functionnality would be to allow us to use a boolean to decide whether we want to display the date in expendable mode.

A third possibility would be to be able to animate calendar when swiping. But less important, that's just for better UX.

Sadly, I just started Flutter so I'm not good enough (at the moment) to implement the features I mentioned and send a pull request. So I rely on someone's will to see those improvments.

Thanks for your attention. I wish everyone a good day !

Hi, is there any plan to add a dependency to your date_utils and remove the existing code for date manipulation?

I spotted the DST bug you fixed in the date_utils has impacted this as well (when expanded and in BST (GMT/UTC+1) the day is off by 1.

For tablets the ability to show a bigger cal would be good.

Also different views:

• month
• week
• day
• schule which just shows them ordered.

https://github.com/wix/react-native-calendars#agenda

No animation applied for swipe left or right action.
Can you add it?

I would like to disable dates before current date. Is there a property to disable onClick on dates which are before than current Date??

On IOs everything works perfectly, on android it has some problems, it doesn't let me expand the calendar, i have to swipe three or four times and it works. Any fix?
