🚀 Getting Started

1. Installation

Add to your pubspec.yaml:

dependencies:
  bee_date_picker: ^0.1.0

2. High-Fidelity Dialogs (The "One-Liner")

Launch a professional, pre-styled picker dialog immediately.

import 'package:bee_date_picker/bee_date_picker.dart';

void _pickDate() async {
  // 1. Single Date
  final DateTime? date = await showBeeDatePicker(context: context);

  // 2. Date Range
  final DateRange? range = await showBeeDateRangePicker(context: context);

  // 3. Specialized
  final DateTime? month = await showBeeMonthPicker(context: context);
  final int? year = await showBeeYearPicker(context: context);
}

3. Inline Picker (The "Embedded" Way)

Use widgets directly in your layouts for custom integration.

BeeDatePicker(
  controller: BeeDateController(initialDate: DateTime.now()),
  onDateSelected: (date) => print(date),
)

🏗️ Mastering the Theme (Signature Pro)

Bee Date Picker uses a centralized BeePickerTheme that adaptations dynamically to system brightness.

Theme Priority

1. Provided theme parameter in individual pickers.
2. Parent BeePickerThemeScope in the widget tree.
3. Default BeePickerDefaults (adapts to Light/Dark mode).

Key Theme Properties

Property	Summary
selectedDayColor	The primary brand color for selected days.
rangeDayColor	Background color for dates within a range selection.
borderRadius	Curvature of picker container and selection markers.
headerTitleTextStyle	Styling for the Month/Year navigation title.
todayBorderColor	Indicator color for the current date.
dialogBackgroundColor	Background color of the popup dialog.

BeePickerThemeScope(
  theme: BeePickerTheme(
    selectedDayColor: Color(0xFFFACC15), // Bee Yellow
    borderRadius: 16,
    headerIconColor: Colors.black,
  ),
  child: MyApp(),
)

⚙️ Behavior Configuration

Fine-tune how the picker behaves using BeePickerConfig.

Constraints & Formatting

Property	Type	Description
minDate	DateTime	Earliest date allowed.
maxDate	DateTime	Latest date allowed.
firstDayOfWeek	Enum	monday or sunday.
showOutsideDays	bool	Show dates from next/prev months.
locale	Locale	Force a specific language/formatting.

Controlling Disabled Dates

config: BeePickerConfig(
  disabledDates: DisabledDates(
    weekdays: [DateTime.sunday], // No selection on Sundays
    predicate: (date) {
      // Custom business logic: e.g., no selection on national holidays
      return isPublicHoliday(date);
    },
  ),
)

---

🎮 Advanced: BeeDateController

For power users, BeeDateController provides programmatic control over the picker's state.

final controller = BeeDateController();

// Navigate programmatically
controller.nextPage();
controller.goToMonth(DateTime(2025, 12));

// Switch View Mode
controller.switchView(BeeCalendarView.year);

// Clear or Set Selection
controller.selectDate(DateTime(2024, 1, 1));

🛠️ Extensibility (Custom Builders)

Wish to replace the header or the day cells entirely? Use our builder API.

BeeDatePicker(
  controller: controller,
  config: BeePickerConfig(
    dayCellBuilder: (context, date, isSelected, isDisabled, isToday, isOutside) {
      return Center(
        child: Text(
          '${date.day}',
          style: TextStyle(color: isSelected ? Colors.amber : Colors.black),
        ),
      );
    },
  ),
)
