Just read your great Medium post

Instead of installing babel-plugin-transform-decorators-legacy, try installing @babel/plugin-proposal-decorators version 7.0.0-beta.47.

You’ll also need to set up your babel configuration in .babelrc a little differently:

{
  "presets": ["react-native"],
  "plugins": [
    [
      "@babel/plugin-proposal-decorators",
      {
        "legacy": true
      }
    ]
  ]
}
