Errors showing up as soon as the project examples are loaded into android studio.

[Charith0401]

Hi! I'm quite new to app development and right now I'm trying to learn how to develop an AR indoor navigation app using flutter. I tried to use this plugin in my project however the moment I load the examples from this project into android studio so many errors pop up I tried changing the compilersdkversion and I got the dependencies but the errors are still showing up could someone please help me with it ? I feel like I'm doing something wrong as everyone else doesn't seem to be having the same issue as I am.

I'll attach a photo for anyone to take a look at and see some of the errors as well. Thanks in advance!

Hi man because you probably are using flutter with null safety because the latest versions of flutter have it, if you don't initialize a variable you ave to put ? after the type.

E.g

ARSessionManager? arSessionManager; ARObjectManager? arObjectManager; ARAnchorManager? arAnchorManager;

and it is the cause of your errors @OfficialImmortal

well, that's understandable. Why is this not present in the example when the package was updated 9 days ago.

Looks like a super old example.

[giovannicampagnolo]

yes the example are old we need to fork it

[nsvetlakov]

[giovannicampagnolo]

: Error: Member not found: 'FirebaseAppPlatform.verifyExtends'.
../…/src/firebase_app.dart:18
    FirebaseAppPlatform.verifyExtends(_delegate);
                        ^^^^^^^^^^^^^

[nsvetlakov]

Hooray! Launched!

[giovannicampagnolo]

maybe your dependencies dosen't support verifyExtends method

[nsvetlakov]

maybe your dependencies dosen't support verifyExtends method

in pubspec.yaml put

dependency_overrides:
  firebase_core_platform_interface: 4.5.1

and download Firebase google-services.json that's it

[nsvetlakov]

i fix it, i made the pull request to @CariusLars

How can I make the 3d model appear when hovering over an image? I can't find such a method. It seems like in ARCore this was also in ARKit

[giovannicampagnolo]

open another issue, is different then this

[nsvetlakov]

You can solve the issue by removing everything related to firebase if you just want to test the plugin, also don't forget google services on the gradle files it work fine by then. you can try the code in https://github.com/othy1010/test_AR_plugin .
