Flutter：将 firebase_ml_vision 依赖项从 0.9.x 升级到 0.10.0

Question

My flutter project runs fine with Firebase ML Vision 0.9.x, if I try to upgrade to 0.10.0 (or higher), it yields the following errors:

FAILURE: Build completed with 2 failures.

1: Task failed with an exception.
-----------
* Where:
Build file 'C:\Users\...\Cache\hosted\pub.dartlang.org\firebase_ml_vision-0.10.0\android\build.gradle' line: 26

2: Task failed with an exception.

BUILD FAILED in 889ms
Exception: Gradle task assembleDebug failed with exit code 1

The first of those two errors is weird because the setup instructions and the package install guidelines both say that firebase_core is not required (anymore).

The second is just plain wrong, as my app's build.gradle specifies compileSdkVersion 30 and the firebase_ml_vision package's build.gradle specifies compileSdkVersion 29 .

Any ideas what's going on?

Answer 1

Found a solution that works: Ignore the setup instructions and add firebase_core as a dependency. Then, add the 'implementations' according to this thread to solve the 'Duplicate class' issues.
