How to use the @babel/plugin-syntax-import-meta.default function in @babel/plugin-syntax-import-meta

module.exports = function babelPresetGitHub(api, { useBuiltIns = false, env = true, modules = false, targets = {} }) {
  targets = Object.assign({}, { browsers: defaultBrowsers }, targets)
  if (targets.browsers === 'mobile') targets.browsers = mobileBrowsers
  if (targets.browsers === 'default') targets.browsers = defaultBrowsers
  const presets = []
  const plugins = [

    require('babel-plugin-transform-invariant-location'),
  ]
  const fullBrowsers = browserslist(targets.browsers)

  if (env) {
    presets.push([require('@babel/preset-env').default, { modules, targets, useBuiltIns: useBuiltIns ? 'entry' : false }])
  } else if (needsRestSpread) {
    plugins.push([require('@babel/plugin-proposal-object-rest-spread'), { useBuiltIns }])
  }
  return { plugins, presets };
};
