Check that the modal bottom sheet is closed by the user manually or by Navigator.pop

[rrifafauzikomara]

showCupertinoModalBottomSheet(
      expand: true,
      context: context,
      backgroundColor: ColorPalettes.white,
      shape: const RoundedRectangleBorder(
        borderRadius: BorderRadius.only(
          topLeft: Radius.circular(10),
          topRight: Radius.circular(10),
        ),
      ),
      isDismissible: true,
      builder: (rootContext) => ManageSavingsPlanSheet(
        argument: ManageSelectArgument(
          iban: widget.argument.iban,
          cashBalance: widget.argument.cashBalance,
          digitalDepotAccountId: widget.argument.digitalDepotAccountId,
          withdrawBalance: widget.argument.withdrawBalance,
          canWithdraw: widget.argument.canWithdraw,
          isPaused: widget.argument.isPaused,
        ),
      ),
    ).then((_) => _getSavingsPlanDetail(context));

Can we check the modal bottom sheet is closed by the user (drag) or by Navigator.pop (from a button inside the modal bottom sheet)?

Because I have a condition when the modal is closed by Navigator.pop want to execute API function (_getSavingsPlanDetail), but if by the user manually is not.

Because for now the _getSavingsPlanDetail is always executed.

There is different ways to achieve this:

1. Via a callback method that you on the onPressed button after Navigator.pop

   showCupertinoModalBottomSheet(
     expand: true,
     context: context,
     backgroundColor: ColorPalettes.white,
     shape: const RoundedRectangleBorder(
       borderRadius: BorderRadius.only(
         topLeft: Radius.circular(10),
         topRight: Radius.circular(10),
       ),
     ),
     isDismissible: true,
     builder: (rootContext) => ManageSavingsPlanSheet(
        onClosedByUser: () {
           _getSavingsPlanDetail(context);
        },
        /// more params
     ),
   );

2. Return a value when tapping the button Navigator.pop(context, true)

   final shouldShowSavings = await  showCupertinoModalBottomSheet<bool>(
     expand: true,
     context: context,
     backgroundColor: ColorPalettes.white,
     shape: const RoundedRectangleBorder(
       borderRadius: BorderRadius.only(
         topLeft: Radius.circular(10),
         topRight: Radius.circular(10),
       ),
     ),
     isDismissible: true,
     builder: (rootContext) => ManageSavingsPlanSheet(
        onClosedByUser: () {
          Navigator.of(rootContext).pop(true);
        },
        /// more params
     ),
   );
   if(shouldShowSavings)   _getSavingsPlanDetail(context);
