iOS: Every outgoing call become Canceled Call.

[ryojiro]

This code is called when outgoing call for CallKit.

flutter_callkit_incoming/ios/Classes/SwiftFlutterCallkitIncomingPlugin.swift

Lines 367 to 381 in 988e33c

	public func provider(_ provider: CXProvider, perform action: CXStartCallAction) {
	let call = Call(uuid: action.callUUID, data: self.data!, isOutGoing: true)
	call.handle = action.handle.value
	configurAudioSession()
	call.hasStartedConnectDidChange = { [weak self] in
	self?.sharedProvider?.reportOutgoingCall(with: call.uuid, startedConnectingAt: call.connectData)
	}
	call.hasConnectDidChange = { [weak self] in
	self?.sharedProvider?.reportOutgoingCall(with: call.uuid, startedConnectingAt: call.connectedData)
	}
	self.outgoingCall = call;
	self.callManager?.addCall(call)
	self.sendEvent(SwiftFlutterCallkitIncomingPlugin.ACTION_CALL_START, self.data?.toJSON())
	action.fulfill()
	}

Especially, these lines are called on outgoing call when a callee answered.

flutter_callkit_incoming/ios/Classes/SwiftFlutterCallkitIncomingPlugin.swift

Lines 374 to 376 in 988e33c

	call.hasConnectDidChange = { [weak self] in
	self?.sharedProvider?.reportOutgoingCall(with: call.uuid, startedConnectingAt: call.connectedData)
	}

However, I think this API is wrong by Apple Documentation. https://developer.apple.com/documentation/callkit/cxprovider/1930695-reportoutgoingcall

This part fixes at #264

Also, this method hasConnected should be called when callee answered.

flutter_callkit_incoming/ios/Classes/Call.swift

Lines 66 to 73 in 988e33c

	var hasConnected: Bool {
	get{
	return connectedData != nil
	}
	set{
	connectedData = newValue ? Date() : nil
	}
	}

However this method is never called in this time. I tried to fix this part but I don't have enough knowledge for Swift so I couldn't.

Please update to version 2.0.0 (make sure you check the changelog, because the input structure has been changed)
await FlutterCallkitIncoming.setCallConnected(this._currentUuid);
