Experiencing issues with your custom Material UI theme not applying? Here are several potential solutions to address this problem:
Different Material UI Library Versions
Ensure you're using consistent versions of the Material UI library. If you're utilizing @material-ui, you're using version 4. If you're using @mui, you're using version 5. Make the necessary changes to your imports to ensure they align with the version you're using.
Change:
import { createTheme, ThemeProvider } from ""@material-ui/core"";
import { orange } from ""@material-ui/core/colors";
To:
import { createTheme, ThemeProvider } from ""@mui/material/styles"";
import { orange } from ""@mui/material/colors";
Also change:
import Icon from ""@material-ui/core/Icon";
To:
import Icon from ""@mui/material/Icon";
Conflicting Packages
In some cases, conflicting packages might interfere with the proper functioning of Material UI. Attempt a clean reinstallation by removing all Material UI and styling-related packages. This can potentially resolve any conflicts and allow for a fresh installation.
Review Migration Documentation
If you're migrating from Material UI version 4 to version 5, refer to the official migration guide at https://mui.com/guides/migration-v4/ for comprehensive instructions and guidance.
Emotion10ThemeProvider
In certain scenarios, adding Emotion10ThemeProvider can facilitate the reflection of theme changes in the UI. Here's an example of how to implement it:
import { ThemeProvider, createTheme } from '@mui/material/styles';
import { ThemeProvider as Emotion10ThemeProvider } from 'emotion-theming';
const defaultTheme = createTheme(); // or your custom theme
<Emotion10ThemeProvider theme={defaultTheme}>
<ThemeProvider theme={defaultTheme}>
<Story {...context} />
</ThemeProvider>
</Emotion10ThemeProvider>

Beyond the specific solutions mentioned above, consider these general troubleshooting tips:
- Ensure that your theme is correctly created and applied.
- Inspect your CSS to verify that styles are being applied as expected.
- Check the console for any errors or warnings related to Material UI.
- Try using a different browser or clearing your browser's cache.
