Dark theme does not work in electron

I am building a electron-react app and am using material-ui (latest v1.0) with success. The controls all seem to display fine - as far as I can see. I use TypeScript and vscode on Windows 10.

I use this code in the assumption it will select the dark theme for the material-ui:

const appTheme = createMuiTheme({
    palette: {
      type: "dark", // does not work??
    }
  });

and have my app react components wrapped with the MuiThemeProvider:

<MuiThemeProvider theme={appTheme}>
    <App />
</MuiThemeProvider>

How I understood it, this should be enough to have theme-support.

• I have searched the issues of this repository and believe that this is not a duplicate.

Expected Behavior

I expect to select the dark theme with this code.

Current Behavior

No reported errors (as far as I can see) and the light theme (default) is used.

Steps to Reproduce (for bugs)

I don’t think codesandbox runs electron…?

1. Use in electron is a valid use-case (is it not?).
2. Brings to light a bug or omission.
3. Would help me tremendously with my project 😉

Context

Making an electron desktop app where I would like to (re)use the material-ui react components.

I’ll try to make an isolated project that demonstrates the problem.

I have called it Reboot after all.
