Hola!
These changes makes implmentation with eslint 9.x.x working without any compat or hassle!

So if anyone wants to merge, we can move this package forward :)

Thanks very much 🙏, do you mind updating the docs with suggested use? Just having trouble getting this to work with V9.

This is how to use it in flat config:

const { defineConfig } = require("eslint/config");
const eslintPluginReactNative = require("eslint-plugin-react-native");

module.exports = defineConfig([
   // your other config
  {
    plugins: {
      "react-native": eslintPluginReactNative,
    },
    rules: {
      // enable the rules you want to use
      "react-native/no-unused-styles": "error",
    },
  },
]);
