Bump event from 2.1.2 to 3.1.0

[dependabot]

Bumps event from 2.1.2 to 3.1.0.

Changelog

Sourced from event's changelog.

Version 3.1.0 (2024-09-10)

1. Minor internal changes
2. Diagnostic logging is available. See the new Diagnostics section in README.md and the example application for further information.
3. Both the subscribe() and broadcast() Event methods produce diagnostic messages at Severity debug. To output these messages use the showLog() method with Severity debug. See the example application.

// Example diagnostics logging output
Event (debug): 2024-09-10 11:37:49.665124Z Subscribed to Event "countChanged:Event<EventArgs>"
Event (debug): 2024-09-10 11:37:49.675925Z Broadcast Event "countChanged:Event<EventArgs>"

Version 3.0.0 (2024-08-05)

This version has BREAKING CHANGES

1. Minimum Dart sdk dependency is now 3.4.0
2. An EventArgs instance is created and broadcast automatically if none provided, i.e.

  var e = Event();
    // is equivalent to...
  var e = Event<EventArgs>(); 

3. An Event can have a name specified. Some code might be subscribed to more than one Event, so this lets one know which Event caused the code to run.

  var e = Event("CountUpdatedEvent");
  e.subscribe((args) => print(args.eventName));
  // outputs "null" until the event is broadcast.
  e.broadcast();
  // outputs "CountUpdatedEvent"

4. EventArgs includes two accessible values:- eventName and whenOccurred. Both have a default value of null, and are only populated when the Event is broadcast.

  // Example without Event name
  var e = Event();
  e.subscribe((args) {
    print(args.eventName); // outputs null
    print(args.whenOccurred); // outputs time of broadcast
  };
  e.broadcast();
// Example specifying an Event name
var e = Event("myEvent");
e.subscribe((args) {
print(args.eventName); // outputs "myEvent"
print(args.whenOccurred); // outputs time of broadcast
};
e.broadcast();

5. The WhenWhy EventArg derived class is DEPRECATED and removed. Use the EventArgs whenOccurred property instead.
