dart sass compile file and resolve imports

Question

I'am working with sass progmatically, So I want to compile a scss file.

const sourcePath = '******/******/****';
const code = sass.compile(sourcePath).css.toString();

I get this error:

An unhandled exception occurred:
@import '.\common\index';
@import '.\login2\index';
@import '.\login-sms\index';
: no such file or directory

I finnd that there is an option importers compile method:

const code = sass.compile(sourcePath, {
    importers: [];
}).css.toString();

But, I don't find what to put in importers!
