Unable to add events to calendar with plugin version 3.0.0

[FedericoMatera]

Just updated to version 3.0.0 and I'm unable to save a new event.

Got this error message:
type 'NoSuchMethodError' is not a subtype of type 'Exception'
in DeviceCalendarPlugin.createOrUpdateEvent (package:device_calendar/src/device_calendar.dart:202:54)

[vondeetzen]

I've setup an example repository here https://github.com/vondeetzen/dc_nosucherrormethod_example with a short tutorial how to reproduce the error. Ran into it a day before.

When I'm running the example project (https://github.com/builttoroam/flutter_plugins/tree/develop/device_calendar/example) it works. Currenlty tested only on iOS 13 simulator (iPhone 11). So I'm currently assuming that there was a mistake while setting device_calendar up or I'm using the code wrong. Permission for the calendar were added in Info.plist.

Running on macOS Catalina and Flutter

Looked at /[...shortened].../.pub-cache/hosted/pub.dartlang.org/device_calendar-3.0.0/lib/src/device_calendar.dart:202 and found the line:

_parsePlatformExceptionAndUpdateResult<String>(e, res);

For debugging purposes I've added a statement

print('e = >$e< and res.success = >${res.isSuccess}< and res.data=>${res.data}<');
_parsePlatformExceptionAndUpdateResult<String>(e, res);

before and got:

e = >NoSuchMethodError: The getter 'data' was called on null.
Receiver: null
Tried calling: data< and res.success = >false< and res.data=>null<

(linebreak was added by the print statement not by me).

Small addition: 2.0.0 also does not work for me (same NoSuchMethodError issue). Everything working fine with 1.0.0+3.

Thanks for the details @FedericoMatera, @vondeetzen. I've had a look and found out I didn't set Uri property for the event to be null-aware - event.url

I'll make sure to add this into next update, as a workaround for now, please set an empty string to the url property of the event: event.url = Uri.dataFromString('')

@FedericoMatera, @vondeetzen, a hotfix v3.0.0+1 has been released now, update the dependency and you shouldn't be getting the error message anymore. You can discard the workaround.

Hi @Brett09 ,
now I have a different error:
Failed assertion: boolean expression must not be null
at DeviceCalendarPlugin.createOrUpdateEvent (package:device_calendar/src/device_calendar.dart:170:15)

allDay is nullable, i think

@FedericoMatera thank you for the patience and contribution. We'll get this reviewed (I've done an initial pass already and it looks good) and merged asap.
