showDateRangePickerDialogOnWidget function

Future<DateRange?> showDateRangePickerDialogOnWidget({ required String cancelText, required String confirmText, required BuildContext widgetContext, required DateRangerPickerWidgetBuilder pickerBuilder, BuildContext? context, Color barrierColor = Colors.transparent, Widget dialogFooterBuilder({ DateRange? selectedDateRange, })?, Offset delta = const Offset(0, 60), })

A function to show the dateRange picker dialog on a widget.

• widgetContext - The context of the widget that will be used to show the dialog.
• context - The context of the dialog. If null, the widgetContext will be used.
• dialogFooterBuilder - A builder to construct the footer widget of the dialog.

• delta - The offset of the dialog from the widget.
• onDateRangeSelected - Called when a date range is selected.
• barrierColor - The color of the barrier.

Implementation

Future<DateRange?> showDateRangePickerDialogOnWidget({
  required String cancelText,
  required String confirmText,
  required BuildContext widgetContext,
  required DateRangerPickerWidgetBuilder pickerBuilder,
  BuildContext? context,
  Color barrierColor = Colors.transparent,
  Widget Function({DateRange? selectedDateRange})? dialogFooterBuilder,
  Offset delta = const Offset(0, 60),
}) {
  // Compute widget position on screen
  final RenderBox renderBox = widgetContext.findRenderObject() as RenderBox;
  final Offset offset = renderBox.localToGlobal(Offset.zero);

  // Show the dateRange picker dialog and get the selected date range
  final dateRange = showDateRangePickerDialog(
      cancelText: cancelText,
      confirmText: confirmText,
      context: context ?? widgetContext,
      footerBuilder: dialogFooterBuilder,
      barrierColor: barrierColor,
      builder: pickerBuilder,
      offset: offset + delta);

  return dateRange;
