Failed to load dynamic library -tflite - flutter

I was trying to run a simple model created using teachable machine from google using tflite_flutter, followed the documentation in the package page.
But the following error occurred
Unhandled Exception: Invalid argument(s): Failed to load dynamic library 'libtensorflowlite_c.so': dlopen failed: library "libtensorflowlite_c.so" not found
this is my code
load() async {
tf.Interpreter inter = await tf.Interpreter.fromAsset('model.tflite');
var input = [
[1.23, 6.54, 7.81, 3.21, 2.22]
];
var output = List.filled(1 * 2, 0).reshape([1, 2]);
inter.run(input, output);
print(output);
}

Adding neovim to home-manager config leads to permission problem

When adding neovim to my home-manager config (nix on MacOs), like so
programs.neovim = {
enable = true;
package = pkgs.neovim;
viAlias = true;
extraPackages = [
pkgs.rnix-lsp
];
};
I get the following error
these 5 derivations will be built:

Any ideas what might cause this?
package takes as input an unwrapped version of neovim (without the python/node… wrapper since home-manager does the wrapping itself) as you can see here. Since this value is anyway set by default you can just remove it:
programs.neovim = {
enable = true;
viAlias = true;
extraPackages = [
pkgs.rnix-lsp
];
};
