Yes, the warning "Unresolved function or method editKnife()" means that the code is trying to call a function/method named editKnife() but it cannot be found or resolved in the current context. To resolve this warning, you need to make sure that the editKnife() function/method is defined and implemented somewhere in your code.
If the editKnife() function/method is supposed to be a part of the same class or file where you are calling it, double-check for typos or syntax errors that might be causing the function/method to be unrecognized. If the editKnife() function/method is defined in a different file or class, make sure to import or include that file/class so that the function/method can be accessed.
Additionally, ensure that the editKnife() function/method is accessing the correct parameters and is properly defined with the correct syntax. If all else fails, try declaring the function/method before the point where it is being called to eliminate the warning.
