tflite version error

[sourav-singh-rawat]

Note: /home/irotech/Desktop/flutter_linux_v1.7.8+hotfix.4-stable/flutter/.pub-cache/hosted/pub.dartlang.org/tflite-1.0.4/android/src/main/java/sq/flutter/tflite/TflitePlugin.java uses unchecked or unsafe operations.
Note: Recompile with -Xlint:unchecked for details.

I am continuously getting this error and i have tried all the version of Tflite till 1.0.1, but still getting the same error.

[techno-disaster]

this looks like a warning? are u sure the build process ends after this?

[sourav-singh-rawat]

No Build Process doesn't end on this, but i am not able to use tflite feature in my app.
Simply it just starting camera, maybe because app is not supporting tflite.

[techno-disaster]

did you load the correct model?

[sourav-singh-rawat]

Thanks, I got it, now it's running fine

[techno-disaster]

@bunny1999 please stop mentioning your error in literally all the issues.

[techno-disaster]

as for the error try checking what your tmp variable is.
