How to use

Make sure to check out examples for more details.

Installation

Add the following line to pubspec.yaml:

dependencies:
  calendar_date_picker2: ^0.0.1

Basic setup

The complete example is available here.

TableCalendar requires you to provide config and initialValue:

• config contains the configurations for your calendar setup and UI.
• initialValue is initial values passed into your calendar picker, initial value must be a List.

The minimum working sample

CalendarDatePicker2(
  config: CalendarDatePicker2Config(),
  initialValue: [],
);

Single Date Picker Configuration

During the initialization of CalendarDatePicker2Config the calendarType of the config instance will by default set to CalendarDatePicker2Type.single, so you don't have to set the calendar type specifically.

Multi Date Picker Configuration

In order to use multi mode date picker, you will need to set the calendarType of config to CalendarDatePicker2Type.multi:

CalendarDatePicker2(
  config: CalendarDatePicker2Config(
      calendarType: CalendarDatePicker2Type.multi,
  ),
  initialValue: [],
);

Range Date Picker Configuration

In order to use range mode date picker, you will need to set the calendarType of config to CalendarDatePicker2Type.range:

CalendarDatePicker2(
  config: CalendarDatePicker2Config(
      calendarType: CalendarDatePicker2Type.range,
  ),
  initialValue: [],
);

Use built-in dialog display method

This package includes built-in support to display calendar as a dialog. To use it, you will need to call showCalendarDatePicker2Dialog, which takes three required arguments: context, config, dialogSize:

...
var results = await showCalendarDatePicker2Dialog(
  context: context,
  config: CalendarDatePicker2Config(),
  dialogSize: const Size(325, 400),
  initialValue: _dialogCalendarPickerValue,
  borderRadius: 15,
);
...
