Expo Config Plugin to disable forced Dark mode.

withDisableForcedDarkModeAndroid.js

// disable forced dark mode to prevent weird color changes on
// certain android devices (Xiaomi MIUI and others enforcing dark mode with view analyzing)
// create a file like "plugins/withDisableForcedDarkModeAndroid.js". Insert this content and edit your app.config.js/app.json

/*
"expo": {
   ...
   ...
   ...
   "plugins": [
       ...,
       ...,
       './plugins/withDisableForcedDarkModeAndroid.js'
   ]
*/

const {
    createRunOncePlugin,
    withAndroidStyles,
    AndroidConfig
} = require('@expo/config-plugins');

function setForceDarkModeToFalse(styles) {
    styles = AndroidConfig.Styles.assignStylesValue(styles, {
        add: true,
        parent: AndroidConfig.Styles.getAppThemeLightNoActionBarGroup(),
        name: `android:forceDarkAllowed`,
        value: "false",
    });

    return styles;
}

const withDisableForcedDarkModeAndroid = (config) => {
    return withAndroidStyles(config, (config) => {
        config.modResults = setForceDarkModeToFalse(config.modResults);
        return config;
    });
};

module.exports = createRunOncePlugin(withDisableForcedDarkModeAndroid, 'disable-forced-dark-mode', '1.0.0');

Thank you @Sorvereign, it helped me! -- SDK 45, phone Redmi note 8 (2021)
In my case, the path was like this:

"plugins": [
[
"./src/plugins/withDisableForcedDarkModeAndroid.js",
{}
]
]

and don't forget to install @expo/config-plugins

A simple

"./plugins/withDisableForcedDarkModeAndroid.js"

is enough. No need to put inside an array. Just tested today on a new project of mine.

I have tried on the Poco F3 (SDK 47), but it does not work. This issue started before I updated to MIUI 14 - Android 13.

Completely insane issue, makes me really mad that at the very start of the new project Expo forces you to eject to solve this 😡. Xiaomi Mi9T Pro, thanks for asking...

You don't need to eject, just use a custom dev-client!

This code works great! the perfect solution for my app. (using SDK 48)

it doesn't work for me :(

I would like to remind you that plugin mods only run in the expo prebuild process, that is, for the changes to take effect it is necessary to generate an .APK (for testing) or .AAB (for playstore).

I don't know why this setting doesn't apply to the expo client, I believe it's possible to generate the .android folder with the npx expo prebuild command and run it on any android emulator (without expo client), that might solve the problem :)

Tested on Xiomi Redmi 9 it worked after building an .apk
