  • I see the same problem. In the tflite gradle file there are dependencies for `compile 'org.tensorflow:tensorflow-lite:+'` which I believe is the root cause of the problem. I'm not sure how gradle is supposed to import and compile `org.tensorflow:tensorflow-lite:+`. – Dark Matter Jul 20 '22 at 17:33

Finally, I got the solution the problem was in the Gradle file which has to be changed from compile to API. The new implementation of Gradle 7.0 and up replaced the compile configuration with API but the tflite plugin is not updated to match Gradle 7 configuration.

You will find the file in this location in windows

C:\Users\[your username]\AppData\Local\Pub\Cache\hosted\pub.dev\tflite-1.1.2\android\build.gradle

Or you can use relative path

%AppData%\Local\Pub\Cache\hosted\pub.dev\tflite-1.1.2\android\build.gradle

OR extract the path from the error message.

For more information please visit Gradl website

Thanks to Masood AL-BADAWI. He means to replace compile with implementation in the mentioned file

C:\flutter\.pub-cache\hosted\pub.dartlang.org\tflite-1.1.2\android\build.gradle' line: 24

The lines should be like:

dependencies {
        implementation 'org.tensorflow:tensorflow-lite:+'
        implementation 'org.tensorflow:tensorflow-lite-gpu:+'
    }
