react-native-community/eslint and TypeScript 3.7

See original GitHub issue

react-native-community/eslint uses

    "@typescript-eslint/eslint-plugin": "^1.5.0",
    "@typescript-eslint/parser": "^1.5.0",
    "prettier": "1.17.0"

which are limited to TypeScript 3.5.*, blocking features like null coalescing and optional chaining. With the overrides below I managed to skip such errors and get only the errors I really had to deal with.

  "resolutions": {
    "**/@typescript-eslint/eslint-plugin": "2.15.0",
    "**/@typescript-eslint/parser": "2.15.0",
    "**/prettier": "1.19.1"
  },

I can create a PR fixing it if you guys want

Have just tested it with 1.1.0 doesn’t seem to work (at least for me) // EDIT: sorry just had to restart the IDE, works now 😊
