Hello,

the type FlatConfig has been replaced with Config, according to the deprecation warning.

I just changed the type with the suggested one.

Cheers!

@irsooti I tried your change but maybe it's because I use the eslint.config.ts since ESLint 9.9.0.

eslint.config.ts:29:3 - error TS2345: Argument of type 'Config<RulesRecord>' is not assignable to parameter of type 'ConfigWithExtends'.

Edit:
It seems to work using Readonly<Linter.RulesRecord> instead of Linter.Config like used here

That's not same thing, RulesRecord only include rules, but recommended.js is different.

eslint-plugin-prettier/recommended.js

Lines 5 to 17 in aa5b59f

	module.exports = {
	...eslintConfigPrettier,
	plugins: {
	...eslintConfigPrettier.plugins,
	prettier: eslintPluginPrettier,
	},
	rules: {
	...eslintConfigPrettier.rules,
	'prettier/prettier': 'error',
	'arrow-body-style': 'off',
	'prefer-arrow-callback': 'off',
	},
	};

This would be a breaking change for eslint v8 users.

It's working for me without my workaround since some time.
