PaperProvider theme doesn't work for release build on IOS

[orcunorcun]

For debug build it show my custom theme but for release it shows purple color instead of mine.

Version:

    "react": "16.8.1",
    "react-native": "0.61.3",
    "react-native-paper": "3.1.1",

Code:

import {DefaultTheme, Provider as PaperProvider} from 'react-native-paper';

const theme = {
  ...DefaultTheme,
  roundness: 7,
  dark: true,
  mode: 'adaptive',
  colors: {
    ...DefaultTheme.colors,
    primary: Colors.mantis,
    accent: Colors.nero,
  },
};

const logger = createLogger();
const persistedReducer = persistReducer(persistConfig, reducers);
const store = createStore(persistedReducer, {}, applyMiddleware(ReduxThunk, logger));
const persistor = persistStore(store);


const App = () => (
  <StoreProvider store={store}>
    <PersistGate persistor={persistor}>
      <PaperProvider theme={theme}>
        <App />
      </PaperProvider>
    </PersistGate>
  </StoreProvider>
);

And also <Portal> cause to crash on release build if I add

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

to babel.config.js file

Error message is:

Same here for iOS and Android. Doesn't work on 3.1.1 or 3.1.0. I had to go down to 3.0.0 in order for my app to run in release build.

It might be caused by this commit 9b74d21

Probably mappings are generated incorrectly and some parts of source code are not available when you use babel plugin. But It's only my guess, someone needs to check that.

Same issue here. I tried to go down to 3.0.0 but it's still crashing on start.
Any news on this?

@kevinsoellner try resetting metro cache: react-native start --reset-cache or expo start -c if using expo

Has this been fixed? I'm getting the same error when I build for release via Xcode:

Invariant Violation: Native module cannot be null.

This error is located at:

I just updated to the latest npm version and tried pod install again. Still getting the same error message even after resetting cache.

EDIT

I figured out my problem. I just assumed since it was talking about Portal.Host, it was related to react-native-paper, especially since someone else had a similar problem. Turns out that I forgot to add a native module manually to my project since I switched computers (library was an ad library, so I just need to download that from their repo and add it to Xcode). Once I commented out my NativeModules code, release started working again. It's because I added a flag to my code if (__DEV__) { return }.
