Theme not working when generating release build APK RNP 4.2.0

[ezekel]

Hi after issuing this command npx react-native run-android --variant=release
and install the release apk to my real device the theme is not working

RN version : react-native@0.63.2

RNP version: react-native-paper@4.2.0

react-native-vector-icons:react-native-vector-icons@7.1.0
Header is black instead default color purplr

but in emulator it works

[github-actions]

Couldn't find version numbers for the following packages in the issue:

• react-native-vector-icons

Can you update the issue to include version numbers for those packages? The version numbers must match the format 1.2.3.

The versions mentioned in the issue for the following packages differ from the latest versions on npm:

• react-native-paper (found: 4.1.0, latest: 4.2.0)

Can you verify that the issue still exists after upgrading to the latest versions of these packages?

It appears to be a trouble with the babel.config.js, I've removed the react-native-paper/babel from my babel.config.js and it seems to work properly when I perform a production build.

same here
Default theme only after build

I notice that a bunch of my theme doesn't work in production builds (fine in test builds).

Is it safe to just remove react-native-paper/babel? What does that plugin usually do?

[JonatanSalas]

I don't know if it is safe to remove it. I think that the plugin might remove unused components and perform other optimizations behind the scenes, but as workaround for now it works well.

I can confirm my apps do build and run, but it's a bit distressing that such a central plugin to the package is malfunctioning on production.

I'm having a similar trouble using expo and react-native-paper. After build the cards of paper are rendering on dark theme even forcing a light theme on expo app.json and using DefaultTheme from react-native-paper. I can't reproduce this on development mode.

I'm using react-native-paper@3.11.0 and expo@39.0.3

I'm not sure if is the same issue anyway.

I have the same issue, I was getting crazy finding the issue. The Babel-Thing is a good workaround for now.

@hirbod I've tried here, but still have the problem here. Can you explain the workaround ?

[projit-thetaonelab]

Same issue. Only work around is use,
AppRegistry.registerComponent(appName, () => App);
as other paper components works fine without the theme.

The work around is to remove this from your babel.config.js file. Removing this plugin does cause the release app size to increase significantly.

  env: {
    production: {
      plugins: ['react-native-paper/babel'],
    },
  },

[hirbod]

Looks like this issue is still unresolved, right?

Yep I ran into it today and found this issue

[raajnadar]

is this happening with latest version?

[kidculli]

I tried with 4.9.2 I can try with the latest @raajnadar

[Bashin]

Still an issue with 4.12.4
Build only shows default theme with 'react-native-paper/babel' in the babel.config.js

[lukewalczak]

Does the issue exist with the react-native-paper latest version?

[kaisoapbox]

This issue still exists with the latest version of react-native-paper@5.10.0 @lukewalczak. As before, removing the babel plugin restores proper theming behaviour.

My environment:

"react": "18.2.0",
"react-native": "0.72.3",
"react-native-paper": "5.10.0",
"react-native-vector-icons": "10.0.0",

[avtarvikas]

facing the same issue in the version react-native-paper : 5.11.4
