Answer 1

When you see a warning like this:

Warning: React version not specified in eslint-plugin-react settings. See https://github.com/yannickcr/eslint-plugin-react#configuration .

Try adding React version settings in your eslint configuration file, such as .eslintrc.js, like below:

// .eslintrc.js
{
  ...
  settings: {
    react: {
      version: 'detect',
    },
  },
}

module.exports = {
  env: {
    browser: true,
    es2021: true,
    jest: true,
    'react-native/react-native': true,
  },
  extends: [
    'eslint:recommended',
    'plugin:react/recommended',
    'plugin:react-hooks/recommended',
    'plugin:react-native/all',
  ],
  parserOptions: {
    ecmaFeatures: {
      jsx: true,
    },
    ecmaVersion: 12,
    sourceType: 'module',
  },
  plugins: ['react', 'react-hooks', 'react-native'],
  rules: {
    'react/jsx-filename-extension': [1, { extensions: ['.js', '.jsx'] }],
    'global-require': 0,
    'operator-linebreak': [2, 'before'],
  },

  settings: {
    react: {
      version: "detect"
    }
  }
};
