Wikitude

Hello,

I am building my second Flutter application on which I have used the Wikitude plugin for AR.

Once I call the arView page I get on run console:

"Uncaught ReferenceError: World is not defined", source: data:text/html, (1)

"Uncaught ReferenceError: AR is not defined", source: data:text/html, (1)

And on the tablet screen I get a message 

Failed to load the Architect World

net::ERR_FILE_NOT_FOUND

I have the architect.js on top of the html page.

What else could cause those errors?

Hello,

any help is highly appreciated.

I have checked with ADE and indeed it cannot load the architect.js file.

Is there any change on the file location?

Hello there,

I would like to have your feedback on this. I cannot use the plugin!

Dear Aitor,

I am using the same implementation as on previous app that I have made.

The only difference between the 2 apps is the different plugin version.

On the previous I have used v.9.6 and now I am using v.9.10 with different flutter and dart versions off course.

But as I have seen there is no difference on your sample code between the different versions.

Hi Aitor,

THe arview is imported from pubspec and then is located on a plugin directory as described on the documentation. The sample html is inside the asset folder and the js file is on the same folder under the js directory. You can check the directory at attached imgs.

How I could sent you the sample (do you refer to sample folder or to whole project)?

You can find them attached.

The old is the one that is currently working and the new is the one that doesn't work.

Hi Aitor,

it's not possible to check the samples because from arview.dart I am using 2 files, one is for the language used and the second is with the poi data. Both of them are called from the dart like below:

this.architectWidget.callJavascript("World.loadLanguage("+jsonEncode(lang)+");");
this.architectWidget.callJavascript("World.loadPoisFromJsonData(" + json.encode(poi) + ");");

So there is no way that you can use my sample without them.

The poi and lang variable are populated correctly when they reach this part of the code. So I suppose that they are entered on the js file without any problem. 

Is there any option to have debug prints from the js in flutter console and not through the AR.logger since I don't have access currently.

I am trying to find the issue here and still no luck.

I have tested with the example from the github, but I am getting the same error.

If I remove the callJavascript lines from the onArchitectWidgetCreated() that I have written above I still get the same error on the alert, but on the flutter console I don't have any error.

When I load the poi with poi.toString() instead jsonEncode(poi) I get 

"Uncaught SyntaxError: Unexpected identifier", source: data:text/html, (1)

and when I use the jsonEncode(poi) I get

"Uncaught ReferenceError: World is not defined", source: data:text/html, (1)

below is the log from the console when I don't load the callJavascript.

I have tested the file on the previous app that I have made and it works, so I believe that the issue is from the 9.10 plugin.

But I cannot go back to the 9.6, because many flutter packages that I use do not have versions for Flutter 1.22.6.

I would like to have your further assistance on this, because I need to deliver the app by the 10th of December and I don't know what else to do.

Thank you

There is definetely something wrong with the v9.10.

As I have written on my posts here when I test the application on the android emulator if the wikitude plugin is enabled I get Unhandled Exception: MissingPluginException(No implementation found for method getApplicationDocumentsDirectory on channel plugins.flutter.io/path_provider, and when it disabled everything works fine.

Then on the mobile or tablet loading I get the Failed to load Architect world.

Shall I test previous versions or maybe v9.11 or 9.12 if you have it ready?
