Which version of googleapis are you using?

googleapis

Hi! I'm using version googleapis 1.0.0.

Sadly, we're limited to what we get from the discovery document

https://github.com/dart-lang/googleapis/blob/3b42c7826f0d07dbc81673c50b54c2141cefb3a0/discovery/googleapis/admob__v1.json#L283-L301

We need to file an issue with the AdMob team.

Thanks! Hope it will be resolved quickly

Remember, you could always fork this repo and hack at this function. If you're adventurous, you don't have to wait!

@kevmoo I thought of that. I debugged somehow 'List<core.dynamic> cast to Map<core.String, core.dynamic>' is not work but if I try to cast without library core it's work.

How to Fix ?

If you makes you feel better, Object-C is having the same problem - google/google-api-objectivec-client-for-rest#447

We're one of at least 3 APIs having the same issue. The short-term workaround is to copy the function that is erroring out and to fix the implementation.

I don't currently have the ability to easily hack the output classes here, but I'll look into it.

try {
if (response.data is List) {
var list = response.data as List;
var dataList = List.from(
list.map((item) => responseType.fromJson(item)).toList()) as K;
return dataList;
} else {
var data = responseType.fromJson(response.data) as K;
return data;
}

This is a method I use in my own responses, maybe it will work for you.

[kevmoo]

@SercanKaya0 – yup. That'll work.

at the moment, try NOT to do one-off hacks to the generated code. Because then I need to manage the output. It's complicated.

Fixed in 22d7103 – shipped in the latest package:_discoveryapis_common

[kevmoo]

I fixed the error reporting, but not the actual issue. Reopening!

Fix is now out in v7
