Overview

flutter_calendar

A calendar widget for Flutter Apps.

Borrowed DateTime utility functions from the Tzolkin Calendar web element.

Usage

Add to your pubspec dependencies:

    flutter_calendar: ^0.0.1

Render the map with one of three options:

1. Default, Material Design

new Calendar()

2. An Expandable Map

new Calendar(
  isExpandable: true;
)

3. Customize It (Standard or Expandable)

new Calendar(
  // A builder function that renders each calendar tile how you'd like.
  dayBuilder: (BuildContext context, DateTime day) {
      return new Text("!");
  },
)

API

// Three optional params:
final VoidCallback onDateSelected;
final bool isExpandable;
final Widget dayBuilder;

Comments

Bug: The calendar repeats some months (JULY - JULY and so on)

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

Added support for dark theme

I have never done a pull request before, so let me know if I'm doing something wrong here. This calendar is working great for me, but I needed it with a dark theme.

Expanded calendar UI issue

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

the project depends on flutter_calendar ^0.0.4 which depends on date_utils ^0.0.1

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"

Another exception was thrown: SliverGeometry is not valid: The "maxPaintExtent" is less than the "paintExtent".

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?

flutter calendar is not working properly in month mode as skips some months or repeat the successive one

From @debutdeveloper on August 23, 2018 9:23

URL: https://pub.dartlang.org/packages/flutter_calendar

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!!

Display month is not updated correctly

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); }); }

flutter_calendar >=0.0.3 depends on date_utils <0.1.0

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

How to start expanded?

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

Add dependency to date_utils

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.

Languages Support

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.

Feature Request: Select date ranges

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.

Flutter_calendar Not compatible with intl 0.16.0 plz update

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.

Allow changing date from parent widget

Allow you to change the date from the parent widget and the Calendar will rebuild to the supplied date. The existing parameter name initialCalendarDateOverride should probably be changed, but for backward compatibility I didn't make that change.
