too many bugs found

[tayyabbashir2224]

when i run this command flutter build apk --split-per-abi
i got following errors..
The plugins flutter_image_compress, local_auth use a deprecated version of the Android embedding.To avoid unexpected runtime failures, or future build failures, try to see if these plugins supportthe Android V2 embedding. Otherwise, consider removing them since a future release of Flutter will
remove these deprecated APIs.
If you are plugin author, take a look at the docs for migrating the plugin to the V2 embedding:
https://flutter.dev/go/android-plugin-migration.

configure dependency accordingly and link firebase account and try again. and as it uses deprecated dependency so you might need to rewrite everything if you update dependency.

Actually I moved on from Flutter ecosystem quite a long time, but it looks like error is due following reason.

when you use latest version of library. some class name is changed, you can check changelog of particular library at https://pub.dev/ and check what changes are done, here problem is this project is using old version of library and you've used new version in pubspec.yaml , so I think in new version some classes and some modification is there for which actually you've to go through library documentation, no other way. and error is configuring firebase authentication so what you can do is learn how to configure firebase authentication and database for that you can read official firebase documentation and configure accordingly.

The getter 'message' isn't defined for the type 'Object'.

please help me .

it is error handling mechanism, if error comes then it will be rendered with Dialog box. make sure that you've configured firebase authentication and all dependency that need in order to work with firebase, so configure firebase with your app. then try again.

[tayyabbashir2224]

hi i have solved almost all errors in the project and now am stucked at permission_handler

[preetmungara]

Great, now you've to configure this https://pub.dev/packages/permission_handler dependency properly.

[tayyabbashir2224]

one thing you should do is whenever any error occurs or something unexpected thing happens, try to search error on google and read discussion about it on stackoverflow and other site, because I might not familiar with all the things [in fact no developer in this world], so search according, you might get answer, because problem I haven't touch flutter from last 1.5 year around so now I'm aware of lot of thing as ecosystem is evolving continuously.
