Repro Code

type MyType = {
  requiredProp: string;
  optionalProp?: string;
}

ESLint Config

module.exports = {
  parser: "@typescript-eslint/parser",
  "rules": {
    "@typescript-eslint/member-ordering": [
      "error",
          {
        "typeLiterals": {
          "optionalityOrder": "required-first"
          }
          }
      ]
  }
};

tsconfig

{
  "compilerOptions": {
    // ...
  }
}

Expected Result

I expect no error when the requiredProp is the first item.
I expect an error when the requiredProp is not the first item.

Actual Result

Error is shown when requiredProp is first item:

Member requiredProp should be declared after all optional members. 2:3 - 2:24

Additional Info

Seems like in the implementation the result for the optionalOrRequired condition is reversed:
