Question 75774 in Flutter Question posted in
The official Flutter documentation can be found here.

can't access fromAsset method of FragmentProgram class, Flutter

I’m trying to write some custom graphics stuff, but got stuck at loading shaders.

I have this:

void loadMyShader() async {
   var program = await FragmentProgram.fromAsset('shaders/myshader.frag');
}

from the webpage: https://docs.flutter.dev/development/ui/advanced/shaders

in VSCode, but I get an undefined method error for .fromAsset()

The above function definition is inside a simple class.
The only method that gets suggested is .compile(), but that expects some spirv code I don’t know.
Is it an issue with the api being beta, or something completely obvious I’m missing here?

I haven’t compiled the code, I just see the error message described above.

    In your pubspec.yaml change the location of where you list your shaders from assets: to shaders:. your final yaml should look like this:

      assets:
    - assets/fonts/
    - assets/icons/
    - assets/images/

  shaders:
    - assets/shaders/simple.frag
    - assets/shaders/toon_cloud.frag
