UnsupportedError (Unsupported operation: Loaded ObjectBox core dynamic library has unsupported version 0.18.1, expected ^0.19.0)

Question

I get this exception at the startup of the app. UnsupportedError (Unsupported operation: Loaded ObjectBox core dynamic library has unsupported version 0.18.1, expected ^0.19.0)

Flutter 3.15.0-15.2.pre • channel beta • https://github.com/flutter/flutter.git
Framework • revision 0d074ced6c (3 hours ago) • 2023-09-21 10:24:15 -0700
Engine • revision 453411bcf3
Tools • Dart 3.2.0 (build 3.2.0-134.1.beta) • DevTools 2.27.0

sdk: '>=3.0.0 <4.0.0'

objectbox: ^2.1.0
objectbox_flutter_libs: ^2.1.0
objectbox_generator: ^2.1.0

I tried it on Windows and Linux and tried the following script like they say in their docs.

bash <(curl -s https://raw.githubusercontent.com/objectbox/objectbox-dart/main/install.sh) In windows I copied the files to System32 and in Linux it installs the .so file globally but it does not work on either platform.

Edit: Same problem with the objectbox example projects.

Answer 1

Downgrade the Pub Cache Dart version of object box to 2.0.0 it will works

This issue was fixed with release 2.3.1. Run flutter pub upgrade and you should be good.

The updated Android Objecybox library should fix this problem.
