How to use the builder-util.hashFile function in builder-util

function hashFileAsync(filename, algo = 'sha512', encoding = 'base64') {
  var builderUtil = require('builder-util');
  return builderUtil.hashFile(filename, algo, encoding);
}

function hashFileAsync(filename, algo = 'sha512', encoding = 'base64') {
  var builderUtil = require('builder-util');
  return builderUtil.hashFile(filename, algo, encoding);
}

export async function createPackageFileInfo(file: string, blockMapSize: number): Promise {
  return {
    path: file,
    size: (await stat(file)).size,
    blockMapSize,
    sha512: await hashFile(file),
  }
}

export async function createPackageFileInfo(file: string): Promise {
  return {
    file,
    size: (await stat(file)).size,
    sha512: await hashFile(file),
  }
}

function hashFileAsync(filename, algo = 'sha512', encoding = 'base64') {
