Built-in calendar views

Flutter Calendar provides nine different calendar views. They enable us to view our events with more convenient layouts. These views can be easily configured with the view property of the Calendar widget.

The views are grouped into the following three categories:

• Common views
• Agenda views
• Timeline views

Common views

The common views include:

• Day
• Week
• Work week
• Month

Note: For more information, refer to the demo for different views in the Flutter Calendar.

Agenda views

Agenda views display appointments as a list in sequential order grouped by days.

Types of agenda views:

• Schedule view: Displays appointments as a list grouped by week, between set minimum and maximum dates. You can customize everything from the date and time formats to the styling of each header. The empty weeks can be hidden.
• Month agenda: Displays an UI under the month layout with the appointments for the current selected date. The month cell displays an indicator when it has appointments on it.

Timeline views

Timeline views visualize appointments with clear event representation using a separate horizontal time axis. This view includes:

1. Timeline day
2. Timeline week
3. Timeline workweek and
4. Timeline month

Loading on demand

While developing an application with Calendar, the most prevalent requirement is the ability to load events on demand in the calendar views. Our Calendar widget provides all the common scheduling functionalities that allow users to load data on demand.

You can build your own custom widget that will be displayed as a loading indicator in the Flutter Calendar when the calendar view changes. In Calendar schedule view, this loading indicator will be displayed when a user reaches the start or end position to load more appointments.

Use the loadMoreWidgetBuilder property to build the busy indicator and the handleLoadMore method to load the appointments on demand.

Note: For more information, refer to the demo for loading more appointments in Flutter Calendar.

Timeline resource grouping

The timeline resource grouping is a discrete view. It allows you to group appointments based on the available resources in the timeline views of the Calendar widget.

You can group appointments and time regions in rows based on the allocated resources in the timeline view. This feature also supports customization, allowing you to assign unique styles to the resource view.

Note: For more information, refer to the demo for Special Regions in the Flutter Calendar.

Recurring events

Easily configure recurring events to be repeated on a daily, weekly, monthly, or yearly basis with optimized recurrence options. You can also skip or change the occurrence of a recurring appointment.

Note: For more information, refer to the demo for Recurrence in the Flutter Calendar.

Time zone with daylight saving time

You can create appointments in various time zones and display them on different views. Our Calendar widget works great with different time zones and considers daylight saving time in a built-in time zone. So, users can view their appointments without variations in timings.

By default, the Calendar behaves by detecting the local time zone. You can control the time zone by specifying it externally using the timeZone property.

Completely customizable UI

The look and feel of the Flutter Calendar elements can be customized using the builders. They allow you to create your own custom view and assign the custom UI to the Calendar elements.

The following builders support complete UI customization in the Flutter event Calendar:

1. Month cell
2. Appointment
3. Schedule view month header 
4. Time region

You can also provide a uniform look to the Calendar’s appearance and format with the beautiful themes support.

Restricting the user interaction

You can restrict the user interaction for the required timeslots through the following features in the Calendar:

• Blackout dates: Disable any date in a month or timeline month view of the Calendar to make it inactive. You can also easily prevent the selection of weekends and holidays by disabling them.
• Time regions: Disable interactions with and selections of any specific time ranges. This is useful when you want to block user interaction during holidays or on any special events and to highlight those time slots.
• Minimum and maximum dates: Restrict date navigation for specific date ranges. The dates that fall beyond the minimum and maximum dates will be disabled for user interaction.

Quick-view navigation

This feature allows you to navigate among calendar views easily. With the header-date picker, quick navigation is provided in the month view when clicking on a month cell. Also, buttons for easy navigation for day, week, workweek and month views are available in the view headers.

Set the allowViewNavigation property to true to enable the quick-view navigation feature in the Flutter Calendar widget.

Calendar features

This Flutter Calendar inherits all the required calendar-related features:

• Flexible working days: Customize the working days in a workweek so that the remaining days will be hidden from view.
• First day of week: Customize the first day of a week as needed. The default one is Sunday.
• Customize leading and trailing dates: Hide the dates of the next and previous months in a calendar to enhance the appearance.
• Current time indicator: Display an indicator on the current time slot of the calendar. You can also customize the color of the indicator.
