I am creating a Navbar in a Project. In my Project I use
- mui/icons-material: ^5.2.5
- mui/material: ^5.2.6
- mui/styles: ^5.2.3
Now My folder structure is
- Root.jsx
- Navbar.jsx
- styles.js
I am having an error of
The `styles` argument provided is invalid.
You are providing a function without a theme in the context.
One of the parent elements needs to use a ThemeProvider.
I have tried to fix with
- Add ThemeProvider at Root.jsx
- Remove from Root.jsx & Add at Navbar.jsx
- & Others
Note: I don't know Material UI. Please help me to get out from this error. Here I am providing my code.

Reset to default 5I also ran into this issue. These are the steps I followed to solve the issue:
Add following import in the component that will use mui: import
Next, create a theme. createTheme
Wrap the component within Themeprovider and pass the theme to it: themeprovider
try this in your Root component:
import React from 'react';
import Navbar from './Navbar';
import {createTheme} from '@mui/material';
import {ThemeProvider} from '@mui/styles';
const Root = () => {
const theme = createTheme()
return (
<ThemeProvider theme={theme}>
<Navbar />
</ThemeProvider>
)}
export default Root
you can find more details in this link https://mui.com/material-ui/customization/theming/
You need to use createTheme function from mui, https://mui.com/customization/theming/ Here you can watch examples. MakeStyles is used to style a specific component, but not the whole application.
so you need to do something like this:
const theme = createTheme({ //here you set palette, typography ect... })
Then you wrap your whole application in ThemeProvider like this...
<ThemeProvider theme={theme}> //Your application </ThemeProvider>
and then, when you use makeStyles({theme}) your theme object will have your described theme values.
I wrote my ThemeProvider in the MainLayout and then received this error message, then i took it in Index component as the parent of the MainLayout then it has been solved
To throw more light to @MAHDI's Answer
Do this:
import { ThemeProvider, makeStyles } from '@mui/styles'
import { createTheme, createTheme } from '@mui/material'
Create a function within your component wrapper:
const useStyles = makeStyles(theme => ({
...... jsx/js style properties .......
}));
function App(){
const theme = createTheme();
return (
<ThemeProvider theme={theme}>
..... Your children components ....
</ThemeProvider>
);
}
export default App;
Those who are migrating MUI from v4 to v5, they might face this error.
Update your imports as shown below:
import { ThemeProvider, makeStyles } from '@mui/styles'
import { createTheme, createTheme } from '@mui/material'
