ui Warning: Prop `className` did not match.

I'm seeing this error Warning: Prop `className` did not match. Server: "__variable_914793 dark" Client: "__variable_914793" in the browser console whenever my app loads

Here's my layout.tsx

import { ThemeProvider } from "@/components/theme-provider";
import "@/styles/globals.css";
import type { Metadata } from "next";
import { GeistSans } from "geist/font";
import { Navbar } from "@/components/navbar";

export const metadata: Metadata = {
  title: "My App",
};

export default function RootLayout({
  children,
}: {
  children: React.ReactNode;
}) {
  return (
    <html lang="en" className={GeistSans.variable}>
      <body className="min-w-[350px]">
        <ThemeProvider
          attribute="class"
          defaultTheme="dark"
          enableSystem
          disableTransitionOnChange
        >
          <Navbar />
          {children}
        </ThemeProvider>
      </body>
    </html>
  );
}

Does anyone know what's happening here?

I'm facing the same issue its related to next theme and hydration , you can find different solutions here https://github.com/pacocoursey/next-themes/issues/169

I get this every time I start up a fresh shadcn project with themes.

I'm currently using this <html lang="en" suppressHydrationWarning>

@nooblyf I still get the warning even when using that (that's actually included in the docs).
