So that's actually a generated class :) When we run the ffi script (https://github.com/tensorflow/flutter-tflite/blob/main/ffigen_tensorflow_lite.yaml) this gets overridden.

@PaulTR, I wonder if there is an estimated timeline for when the tflite_flutter package will be updated to address the recent issues with the Dart upgrade?

[craiglabenz]

This should be a matter updating all the dependencies everywhere. What's happening is that ffigen is generating newer code than other aspects of the pubspec.yaml file are cool with.

We can update the ffigen package to 8.0.0 and resolve this issue. This issue has been resolved after 8.0.0 version. https://pub.dev/packages/ffigen/changelog
