I had the same problem.
I'm using logEvent alternatively for now.

example:

FacebookAppEvents().logEvent(
  name: "fb_mobile_content_view",
      parameters: {
        "content": 'XXX',
        "currency": 'XXX',
        "value": 'XXX',
  },
);

app events names are following.

Thanks! I'll try it as a temporary solution

[DennisAlund]

Thank you for the report.

Not sure I fully understand what the scope of the problem is? You are missing some event methods?

Regarding the one you mentioned in the example, am I understanding it correctly that you are having an issue with the logViewContent() method as described in #73?

[DennisAlund]

If the issue is that you're missing some alias methods for logging events, there are a a few paths to take on that

1. Make a list of the exact methods you'd want/need and wait for me or someone to implement it.
2. Make a pull request with said methods implemented 🤗
3. In the meanwhile, you can create extension methods to implement them in your own project, while waiting. See comments made in this PR: Added Support for ISOCurrency in complete registration #67 (comment)

The problem is that I can't see the standard events in my Facebook dashboard (fb_mobile_purchase, fb_mobile_add_to_cart, fb_mobile_initiated_checkout). Those are not possible to be tracked with Facebook campaigns because are not getting triggered. The rest are showing in my Facebook Analytics.

I'm not sure what kind of problem can it be, I'll try with as @naoaki-kaito suggested, and I'll come back to report it as a temporary solution.

I tried but still doesn't work, have you done something special? Do you use "await" to track it?

An example of what I have:

_facebookAppEvents.logEvent(
      name: "fb_mobile_add_to_cart",
      parameters: {
        "fb_content": [
          {"id": itemId, "quantity": quantity},
        ],
        "content_type": itemCategory,
        "fb_currency": currency,
      },
      valueToSum: price,
    );

[naoaki-kaito]

@RicardoRB

fb_content must be String.

"fb_content":  "[{\"id\": \"$itemId\", \"quantity\": $quantity}]"

[DennisAlund]

Please see example for logViewContent

flutter_facebook_app_events/lib/facebook_app_events.dart

Lines 197 to 200 in d8e423b

	return logEvent(
	name: eventNameViewedContent,
	parameters: {
	paramNameContent: content != null ? json.encode(content) : null,

[DennisAlund]

@RicardoRB please update to v0.11.1 where add to cart as been added

flutter_facebook_app_events/lib/facebook_app_events.dart

Lines 214 to 231 in 8d27fb4

	Future<void> logAddToCart({
	Map<String, dynamic> content,
	@required String id,
	@required String type,
	@required String currency,
	@required double price,
	}) {
	return logEvent(
	name: eventNameAddedToCart,
	parameters: {
	paramNameContent: content != null ? json.encode(content) : null,
	paramNameContentId: id,
	paramNameContentType: type,
	paramNameCurrency: currency,
	},
	valueToSum: price,
	);
	}

Solved in version: 0.11.2

Thanks @DennisAlund and @naoaki-kaito now it works pretty fine. I had to use the exactly variables that the events also need 😃
