Web Errors/Exceptions cannot be caught when using parent plugin about flutter_google_places_sdk

[matanshukry]

@kaminoan-dev I can't seem to reproduce that.
Specifically, you can look at the example under flutter_google_places_sdk - and launch it on web.
Both in debug and run, when you don't provider the key - you'll get the error showing up on the UI.

That can only happen if the catch block, much like yours, is executed - since there it will assign the error that will then be shown in the UI. I tried again and it works on both debug and run modes.

And much like in your description, that example project has dependency on flutter_google_places_sdk rather than directly on the web dependency.

Can you make a reproducible example?
Or perhaps a gist of the differences you can make in the example, as to when the catch block does not execute?

(I have updated my initial post for more details)

I kept getting the same error using the example app in the flutter_google_places_sdk project with a clean clone of the repo. I have then done a fresh intallation of everthing (Android Studio, Flutter, Dart, the package repository, etc) on Windows, since I though it may be relate somehow to using the Linux/Ubuntu version of Chrome... and I still get those error.

As I say, I have just cloned this repository without any modifications of the code and get those errors.

@kaminoan-dev you mentioned you keep getting "those errors" while using the repository without any modifications.

To be clear then - you're not seeing the error on the web?

Attaching image to what is hapenning, which is what should happen.

Using the repository without any modifications and leaving the API_KEY = '' I do get the same error as in you have in your screenshot. That works perfectly.

However, if it is replaced by an invalid value to force another type of error, for example API_KEY = 'DummyKeyValue', the low level error is not caught and the execution gets stuck.

This is an issue with flutter (or rather, dart).
Created ticket with flutter: flutter/flutter#97082
which in turn created ticket with dart: dart-lang/sdk#48239

[kaminoan-dev]

Thank you very much. I will subscribe to those issues to follow.

@kaminoan-dev flutter issue closed with a comment saying it's a valid behavior.

Looking again I agree; the promise it self is never completed in javascript either (neither successfully nor with an error), so it make sense for the dart code to never complete the future either.

Closing as well.
