Save the file as install.bat and put the file in root directory of your project.
Open in explorer and open a command window there.
Type install.bat and press Enter. Use install.bat -d (Windows) instead if you wish to use GpuDelegateV2 and NnApiDelegate.

Save the file as install.sh name and put the file in root directory of your project.

Answer 2

You need to add a file in the root directory in the app found in
tflite_flutter package. tflite_flutter. You can also find it here.
just download the file and place it into the root directory in your app and double click to install the needed information. (For Windows)

Answer 3

I had the same error. Hopefully this is helpful to someone.
After using the install.sh file, that error showed (only on Android, iOS worked fine). But I had changed the wget to curl in the install file and it had downloaded a redirect html page.
The replacement that worked for me was:
# wget "${URL}${TAG}/$1" -O "$1" # Replaced with the below line
curl -L "${URL}${TAG}/$1" -o "$1"
Try to confirm that the files you have downloaded are the correct files. You can inspect these files in <projectdirectory>/android/app/src/main/jniLibs. They should be binary files that begin with ^?ELF, not html files like what I had.
