Expo Config Plugin to disable forced Dark mode.

withDisableForcedDarkModeAndroid.js

// disable forced dark mode to prevent weird color changes
// eslint-disable-next-line @typescript-eslint/no-var-requires
const { createRunOncePlugin, withAndroidStyles, AndroidConfig } = require('expo/config-plugins')

function setForceDarkModeToFalse(styles) {
  const newStyles = AndroidConfig.Styles.assignStylesValue(styles, {
    add: true,
    // ############# FOLLOW IF YOU'RE ON SDK 52 #############
    // TODO: AndroidConfig.Styles.getAppThemeGroup() will be available in SDK 52 (or expo/config-plugins 9+), for now I just hardcoded AppTheme
    // parent: AndroidConfig.Styles.getAppThemeGroup(),
    parent: { name: 'AppTheme' },
    name: `android:forceDarkAllowed`,
    value: 'false',
  })

  return newStyles
}

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'

Hi, thanks for such a piece of code
however it has not worked on my side

Here is my app.json

The exact syntax you put plugins: [['./plugins/withDisableForcedDarkModeAndroid.js']] was not working:

Did I miss something ?

have to change something?

For me it has never worked although some people recommend replacing value: "false",by value: false,. I have tried both with no success...

while I don't have any definitive answer to this problem, I solved it in the configuration of my Xiaomi note 8, I disabled dark mode in individual applications

I have this running since Expo SDK 44 and its working fine for me.

Hey buddy, ty for the code! Solved the problem here :D

Hey friend! I have writted an answer on stackoverflow to help others and maybe will be useful for you too.
You can check the full solution for dark mode problem here -> https://stackoverflow.com/a/74239739/16539417

@top-kat did you manage to solve the problem?

@cosimonegri sorry I didn't, I gave up trying...

@top-kat I think i found the solution:

The plugin key accepts arrays of arrays, you have to wrap the plugin on another array. Hope it helps!

Thanks @Sorvereign, I'll try that 👍

Hi @deywersonp I have followed your steps in the stack overflow post but still does not work for me.

Thanks @Sorvereign, I'll try that 👍

Did it help?

Unfortunatedly as commented here it does not work for Redmi Note 9 or Redmi 9T (Expo SDK 47) 😢

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

Awesome
It work for me

Worked for me too.

Worked here, thanks for this.

Worked, thanks!

I'm using react-native-edge-to-edge in my app

changed the plugin accordingly

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

My styles.xml looks like this but forceDarkAllowed: false is not applied.

<resources xmlns:tools="http://schemas.android.com/tools">
<style name="AppTheme" parent="Theme.EdgeToEdge">
  <item name="android:textColor">@android:color/black</item>
  <item name="android:editTextStyle">@style/ResetEditText</item>
  <item name="android:editTextBackground">@drawable/rn_edit_text_material</item>
  <item name="colorPrimary">@color/colorPrimary</item>
  <item name="android:windowLightStatusBar">true</item>
  <item name="android:forceDarkAllowed">false</item>
</style>
<style name="ResetEditText" parent="@android:style/Widget.EditText">
  <item name="android:padding">0dp</item>
  <item name="android:textColorHint">#c8c8c8</item>
  <item name="android:textColor">@android:color/black</item>
</style>
<style name="Theme.App.SplashScreen" parent="AppTheme">
  <item name="android:windowBackground">@drawable/splashscreen</item>
</style>
<style name="BootTheme" parent="Theme.BootSplash">
  <item name="postBootSplashTheme">@style/AppTheme</item>
  <item name="bootSplashBackground">@color/bootsplash_background</item>
  <item name="bootSplashLogo">@drawable/bootsplash_logo</item>
</style>
</resources>

Sorry, here is the updated file which works with EdgeToEdge @felippewick

// disable forced dark mode to prevent weird color changes
// eslint-disable-next-line @typescript-eslint/no-var-requires
const { createRunOncePlugin, withAndroidStyles, AndroidConfig } = require('expo/config-plugins')

function setForceDarkModeToFalse(styles) {
  const newStyles = AndroidConfig.Styles.assignStylesValue(styles, {
    add: true,
    // TODO: AndroidConfig.Styles.getAppThemeGroup() will be available in SDK 52 (or expo/config-plugins 9+), for now I just hardcoded AppTheme
    // parent: AndroidConfig.Styles.getAppThemeGroup(),
    parent: { name: 'AppTheme' },
    name: `android:forceDarkAllowed`,
    value: 'false',
  })

  return newStyles
}

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'
)

If you're on SDK52, you can change the TODO

Updated the gist

@hirbod forceDarkAllowed is being copied to the styles.xml file. But it is not being applied in the build. Using expo android release build.
Splash screen (background color given as white using expo-splash-screen plugin) is still showing a black background when in dark mode.

I have given userInterfaceStyle: light in app.config.ts

I tried applying false under Theme.App.SplashScreen, still same result. I am testing in a Redmi phone. Any help?
