ESLint: 8.56.0

Error: Key "plugins": Cannot redefine plugin "react".

More Info

When defining a plugin key in the flat config ESLint enforces that you only ever redefine they key with the same plugin. This check is done by comparing by reference -- i.e. configA.plugin.react === configB.plugin.react

eslint-plugin-react fails this check because it defines its "plugin" in two locations:

For this to work there needs to be exactly 1 copy of the "plugin" defined by the package.
For example:

const plugin = { ... };
plugin.configs = {
  recommended: {
    plugins: { react: plugin },
    rules: { ... },
  },
  all: {
    plugins: { react: plugin },
    rules: { ... },
  },
});
