React Native 0.73 Onboarding Flash Loading & Blank Screen

[batusenyuz]

Description

Hi Everyone,

// Place this code after "[self.window makeKeyAndVisible]" and before "return YES;"
UIStoryboard *sb = [UIStoryboard storyboardWithName:@"LaunchScreen" bundle:nil];
UIViewController *vc = [sb instantiateInitialViewController];
rootView.loadingView = vc.view;

We can no longer paste this code into the AppDelegate.m file. Not working.

https://reactnative.dev/docs/publishing-to-app-store

this code is not working

My app.tsx file is as below.

import React, {useEffect} from 'react';

import {AuthContext} from './contexts/AuthContext';
import {UserContext} from './contexts/UserContext';

import {useAuth} from './hooks/useAuth';

//Navigation
import {NavigationContainer} from '@react-navigation/native';
import MainStack from './navigations/MainStack';
import AuthStack from './navigations/AuthStack';
import {Host} from 'react-native-portalize';
import {GestureHandlerRootView} from 'react-native-gesture-handler';
import {LogBox, useColorScheme} from 'react-native';
import {darkTheme} from './theme/dark';
import {lightTheme} from './theme/light';
import {createNativeStackNavigator} from '@react-navigation/native-stack';
import LoadingScreen from './components/LoadingScreen';
import {BottomSheetModalProvider} from '@gorhom/bottom-sheet';

import PushNotification from 'react-native-push-notification';
import messaging from '@react-native-firebase/messaging';

const RootStack = createNativeStackNavigator();

const App = () => {
  React.useEffect(() => {
    const unsubscribe = messaging().onMessage(async remoteMessage => {
      //Alert.alert('A new FCM message arrived!', JSON.stringify(remoteMessage));
      console.log(remoteMessage);
      PushNotification.localNotification({
        channelId: 'wondera',
        color: '#7a96a2',
        title: remoteMessage.notification.title, // (optional)
        message: remoteMessage.notification.body,
        picture: remoteMessage.data.fcm_options.image,
      });
    });

    return unsubscribe;
  }, []);

  const config = {
    screens: {
      AuthStack: {
        screens: {
          Login: 'login',
          Register: 'register',
        },
      },
      MainStack: {
        screens: {
          Home: {
            screens: {
              Meditasyon: 'meditation',
            },
          },
        },
      },
    },
  };

  const linking = {
    prefixes: ['https://wondera.co', 'wondera://'],
    config,
  };

  const scheme = useColorScheme();

  const {auth, state} = useAuth();

  function renderScreens() {
    if (state.loading) {
      return <RootStack.Screen name={'Loading'} component={LoadingScreen} />;
    }

    return state.user ? (
      <RootStack.Screen name={'MainStack'}>
        {() => (
          <UserContext.Provider value={state.user}>
            <MainStack />
          </UserContext.Provider>
        )}
      </RootStack.Screen>
    ) : (
      <RootStack.Screen name={'AuthStack'} component={AuthStack} />
    );
  }
  React.useEffect(() => {
    LogBox.ignoreAllLogs();
    //PushNotification.localNotification({
    //  channelId: 'overdaze',
    //  color: '#c71b1b',
    //  title: 'deneme', // (optional)
    //  message: 'deneme',
    //  picture: remoteMessage.data.fcm_options.image, // (required)
    //});
  }, []);

  return (
    <GestureHandlerRootView style={{flex: 1}}>
      <AuthContext.Provider value={auth}>
        <BottomSheetModalProvider>
          <NavigationContainer
            linking={linking}
            theme={scheme === 'dark' ? darkTheme : lightTheme}>
            <Host>
              <RootStack.Navigator
                screenOptions={{
                  headerShown: false,
                  animationEnabled: false,
                }}>
                {renderScreens()}
              </RootStack.Navigator>
              {/* <RootStack /> */}
              {/* <AuthStack /> */}
            </Host>
          </NavigationContainer>
        </BottomSheetModalProvider>
      </AuthContext.Provider>
    </GestureHandlerRootView>
  );
};

export default App;

While waiting for the RenderScreen command, LoadingScreen appears. But I want either MainStack or AuthStack to be opened before this loadingScreen appears. I don't want to use plugins like react-native-splash-screen.

How can I avoid this problem?

⚠️

Newer Version of React Native is Available!

ℹ️

You are on a supported minor version, but it looks like there's a newer patch available - 0.73.7. Please upgrade to the highest patch for your minor or latest and verify if the issue persists (alternatively, create a new project and repro the issue in it). If it does not repro, please let us know so we can close out this issue. This helps us ensure we are looking at issues that still exist in the most recent releases.

It looks like that documentation should be updated.

In 0.74 a new customizeRootView function was added - #42088, which I think can be used something like this:

#import <React/RCTRootView.h>

// ...

- (void)customizeRootView:(RCTRootView *)rootView
{
  UIStoryboard *sb = [UIStoryboard storyboardWithName:@"LaunchScreen" bundle:nil];
  UIViewController *vc = [sb instantiateInitialViewController];
  rootView.loadingView = vc.view;
}

In 0.73 probably something like this could work?

#import <React/RCTRootView.h>

// ...

- (UIView *)createRootViewWithBridge:(RCTBridge *)bridge
                          moduleName:(NSString *)moduleName
                           initProps:(NSDictionary *)initProps
{
  RCTRootView *rootView = (RCTRootView *)[super createRootViewWithBridge:bridge moduleName:moduleName initProps:initProps];
  UIStoryboard *sb = [UIStoryboard storyboardWithName:@"LaunchScreen" bundle:nil];
  UIViewController *vc = [sb instantiateInitialViewController];
  rootView.loadingView = vc.view;
  return rootView;
}

Thanks @mlazari, do you think this will solve the loading issue in the app.tsx file? I want the launchscreen to appear until the renderscreens function is completed.

[mlazari]

@batusenyuz Not sure about that, I just indicated where I think is the new place for that code in 0.73 / 0.74. I am not using it and didn't test it, so not sure if that's correct or not.

[caglardurmus]

This #44195 (comment) solved my problem on 0.74.0. I am using same "LaunchScreen" in 0.70.14 and it works perfect. But in this version its zooming before the exit. I tried to disable animation but i cant. Is anyone has the same issue?

[batusenyuz]

Hi @caglardurmus, I'm also having the zoom animation issue.

[caglardurmus]

Any solution?

[batusenyuz]

react native library and documentation should be updated according to new updates and this should be done urgently.
