[eslint plugin] Conflict between TypeScript and ESLint when private property

[baruchiro]

Intended outcome:

I'm trying to exclude a field from being made observable using makeObservable with false annotation, as documented in the MobX documentation. The following code should work:

import { makeObservable } from "mobx";

export class MyStore {
  private count = 0;

  constructor() {
    makeObservable(this, {
      count: false,
    });
  }
}

Actual outcome:

I'm getting contradictory TypeScript/ESLint errors:

1. When the count property is not specified in makeObservable:

Missing annotation for `count`. To exclude a field, use `false` as annotation. (ESLint)

2. When adding count: false as suggested by the first error:

Object literal may only specify known properties, and 'count' does not exist in type 'AnnotationsMap<this, never>'. (ts)

This creates a catch-22 situation where ESLint requires the annotation but then TypeScript doesn't accept it.

How to reproduce the issue:

I've created a minimal reproduction repository that demonstrates this issue:
example-mobx-eslint-bug

Steps to reproduce:

1. Clone the repository
2. Install dependencies
3. Observe the TypeScript errors in the code
