I have a problem running the Flutter project - image

hi have this error when I tryng to run my Flutter application
I'm beginner using Flutter, thank to your help.
There are my dependencies in the YAML file.
flutter:
sdk: flutter
cupertino_icons: ^1.0.0
generic_bloc_provider: ^1.0.8
firebase_auth:
google_sign_in:
firebase_storage: ^2.1.0
cloud_firestore: ^0.9.13
image_picker: ^0.5.4+3
cached_network_image: ^0.8.0

The problem is with cached_network_image: ^0.8.0
Try flutter clean in terminal window.
If the above does not solve the issue, then try removing cached_network_image: ^0.8.0 from pubspec.yaml and save pubspec.yaml. Run flutter pub get in terminal window Then add cached_network_image: ^0.8.0 back again and run flutter pub get in terminal window.
If the above does not solve the issue, then try to install a different version of the plugin, the current version is cached_network_image: ^2.3.3
I think the 3rd option should solve the issue. If not there is one more thing you can try.

Flutter ios: I'm getting "(No implementation found for method Firebase#initializeCore on channel plugins.flutter.io/firebase_core)", can't see why

I'm new to flutter and I've received a "working Android" project which I should adapt to iOS, at least I need it to make it boot and such.
After some reading here and there and then some additional googling I've come with a version of the flutter app that Xcode 13 can compile and launch on the simulator without any problem, but once it runs then some kind of initialization process fails with this error:
MissingPluginException(No implementation found for method Firebase#initializeCore on channel plugins.flutter.io/firebase_core)
I read the words of the message, I understand what they say but I don't understand what they mean.
I already did a flutter clean a flutter pub get then I went into the ios folder to do a pod install/update. Typically I delete Pods folder just in case (to have a even cleaner environment)...
The pubspec.yaml relevant lines I have are these:

(I got this simplified version executing this command line: cat ios/Podfile.lock | grep " - " | grep "(" | grep -v " "
EDIT: I did some 'flutter pub upgrade' to raise my libraries versions a bit. The versions of the above list are the last ones I'm using.
EDIT: Here I add also some excerpt from my lib/main.dart file
...
import 'package:firebase_core/firebase_core.dart';
Future<void> main() async {
// This is for Firebase
WidgetsFlutterBinding.ensureInitialized();
HttpOverrides.global = PolarStarHttpOverrides();
// Launch app after splash
runApp(MyApp());
}
class MyApp extends StatelessWidget {
final Future<FirebaseApp> _fbApp = Firebase.initializeApp();
#override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Flutter Demo',
theme: ThemeData(
primarySwatch: Colors.blue,
),
home: FutureBuilder(
future: _fbApp,
...
I'm not sure about what else to look for, Xcode builds ok, min SDK version is set to 11, the app builds, but it doesn't go beyond some ugly banner on screen claiming "Something went WORNG" (sic)
This error appears in some other people's Stack Overflow questions but for Android, and I'm using iOS. My coworker (using android) has no apparent problem whatsoever booting and running the flutter app.
I've read documentation here and there, but nothing has lead me to any relevant fix...
Is there some additional detail I might have overlooked?
EDIT: I've already tried many different cleaning approaches (as running "flutter clean" and some other similar commands for the "ios" subproject ) to no avail. I also tried some "flutter pub upgrade" (instead of 'get') in case some newer version libraries could appear (and some of them did, but to no avail again).
Add firebase_core :any in pubspec.yaml, delete PodFile.lock Run flutter clean then flutter pub get. Then navigate to ios folder in terminal. Run pod install. Now you should be able to run it successfully.
Remove podfile.lock,.symlinks, Pods
Now "flutter pub get" & install pods using "pod install"
after that just open XCode again..

How do I update just the "nativescript-vue" package in my project?

I'm new to Nativescript and Mobile app development in general. How do I update just the "nativescript-vue" package in my project? My project has nativescript-vue version 2.4.0, but I'm trying to update to version 2.6.1.
Here is a snippet from the packson.json in my project.
"#nativescript/theme": "~2.2.1",
"nativescript-vue": "~2.4.0",
"tns-core-modules": "~6.3.0"
Either change in package.json to "nativescript-vue": "~2.6.1", and run npm install or simply run npm update nativescript-vue.
Ok, I figured out how to do it.
From the terminal I ran the following command...
npm i nativescript-vue#2.6.1
You could open the Project in vscode and run the command from the terminal there too.
To get the latest version run
npm i nativescript-vue#latest

why can't create new app in react native

I'm beginner in react-native and I doing steps in a website of react-native
and the app is working right,
but after doing some update
npm i react#latest --save
npm i react-native#latest --save
react-native upgrade
after that, I can't create any project by
react-native init projectName
I get this error
image link
This is actually a problem on Windows with the latest version of react native (0.56)
GitHub Issue
Try using version 0.55.4 by typing react-native init --version="0.55.4" projectName
Not every version of react-native is compatible with every version of react. In the screenshot you sent, it says you need react#16.4.1 for react-native#0.56.0. Try doing npm i react#16.4.1 --save and then try react-native init projectName again.

main.jsbundle does not exist. this must be a bug with + echo 'react native

I tried to archive my react native project using Product > Archive on XCode9.2. But Xcode produce this error:
File /Users/louis/Library/Developer/Xcode/DerivedData/Scavenger-evyvzocndqoghkclcbwewolywniz/Build/Products/Release-iphoneos/Scavenger.app/main.jsbundle does not exist. This must be a bug with
My Environment:
OS: macOS Sierra 10.12.6
Node: 9.3.0
npm: 5.5.1
Watchman: 4.7.0
Xcode: Xcode 9.2 Build version 9C40b
Android Studio: 3.0 AI-171.4443003
Packages: (wanted => installed)
react: ^16.0.0 => 16.2.0
react-native: ^0.50.3 => 0.50.4
I also tried to run on terminal
react-native bundle --entry-file='index.ios.js' --bundle-output='./ios/Scavenger/main.jsbundle' --dev=false --platform='ios' --assets-dest='./ios'but ended up with error Loading dependency graph...
Unexpected end of JSON input
XCode error.
This issue take me some days to fixed. I got this issue when run the build on travis-ci.
Here is my fix:
Add this line to scripts in your package.json file.
"build:ios": "react-native bundle --entry-file='index.js' --bundle-output='./ios/main.jsbundle' --dev=false --platform='ios'"
Now your can run the command to generate main.jsbundle.
yarn build:ios or npm run build:ios
Open the Xcode > Select project target > add main.jsbundle to Copy Bundle Resource in Build Phases. (image below).
This happens when there is no offline bundle file in your project, I had the same problem and this worked for me.
I have added the below line to my package.json file, under scripts section, so I don't have to type it every time I want to generate an offline bundle.
"build:ios": "react-native bundle --entry-file='index.ios.js' --bundle-output='./ios/YourAppName/main.jsbundle' --dev=false --platform='ios' --assets-dest='./ios'"
And then run this command in your application projects folder:
npm run build:ios
After running the above command, new main.jsbundle will be generated in your ios/YourAppName directory.
Next, open your project using XCode, right click on your project name then click Add Files to "YourProjectName", choose the main.jsbundle file that was generated, and then build again.
Now it might be working well.
I am using:
"react": "16.0.0-alpha.12",
"react-native": "^0.48.3",
Comment this line in AppDelegate.m
jsCodeLocation = [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:#"index" fallbackResource:nil];
Use this line:-
jsCodeLocation = [[NSBundle mainBundle] URLForResource:#"main" withExtension:#"jsbundle"];
After that run this to make jsbundle:-
react-native bundle --entry-file index.js --platform ios --dev false --bundle-output ios/main.jsbundle --assets-dest ios
Run after this command in xcode .
Hope it will make bundle and there is no such error after that ...
Thanx
if you update the xcode and get this error then solution is
in terminal of your root project fire following commands
1. sudo xcode-select --reset
2. npx react-native bundle --entry-file ./index.js --platform ios --bundle-output ios/main.jsbundle
during second command if you found any error relative to JS then fix it
After successfully running second command this error will be gone
I was facing this issue after I ejected from the expo to add in-app purchases.
I did the following to get it to work
cd <your repo>
npx react-native bundle --entry-file ./index.js --dev false --reset-cache --platform ios --bundle-output ios/main.jsbundle --assets-dest ./ios
After the above commands are run you have to drag and drop the main.jsbundle and the assets into your Xcode and link it by reference and not group
Recommend to use the latest Xcode and React Native versions.
My React Native Version: 0.56 and Xcode 10
Step 1: Change AppDelegate.m file
// jsCodeLocation = [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:#"index" fallbackResource:nil];
#ifdef DEBUG
jsCodeLocation = [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:#"index" fallbackResource:nil];
#else
jsCodeLocation = [[NSBundle mainBundle] URLForResource:#"main" withExtension:#"jsbundle"];
#endif
Step 2: Change Xcode Build Configuration to "Release"
Goto Products> Scheme> Edit Scheme> change Debug to release
if you are using Xcode 10+ please change Build system to Legacy Build System under File> ProjectWorkSpace Settings> Build System
Step 3: Upgrade your "babel-preset-react-native" to 5.0.1, if it does not exist in your package.json file please add it.
Remove NodeModules and package.lock file and add it (npm install or yarn install).
Step 4: Change ".babelrc.js" file
Add " presets: ["module:metro-react-native-babel-preset"]
Step 5: Open Terminal
Open the terminal and navigate to your project directory run this command
"react-native bundle --entry-file index.js --platform ios --dev false --bundle-output ios/main.jsbundle --assets-dest ios/assets"
this will generate a "main.jsbundle" file in iOS folder
Step 6: Add "main.jsbundle" file into Xcode.
Open Xcode and navigate to "Build Phase" under "Copy Bundle Resource" add "main.jsbundle" file.
Clean your project also clear your derived data in Xcode.
This will build your project in Release mode.
For "Archive" error
Add this dependency into your "pod file"
pod 'React', :path => '../node_modules/react-native', :subspecs => [
'CxxBridge'
]
pod 'yoga', :path => '../node_modules/react-native/ReactCommon/yoga'
pod 'DoubleConversion', :podspec => '../node_modules/react-native/third-party-podspecs/DoubleConversion.podspec'
pod 'glog', :podspec => '../node_modules/react-native/third-party-podspecs/glog.podspec'
pod 'Folly', :podspec => '../node_modules/react-native/third-party-podspecs/Folly.podspec'
Remove pod and pod.lock and add again. (pod install)
Happy Coding :)
You need to run the following command:
react-native bundle --entry-file ./index.js --platform ios --bundle-output ios/main.jsbundle
After that, the app with the static bundle is installed on the real device. But because the nature of the static file, whenever I modify the source code, I need to run that command again to reflect the changes.
(You can see next error in command)
Problem solved after I rewrite shell script. Project > Build Phases > Bundle React Native code and images. There was blank space character in the script.
This commnad works for me.
react-native bundle --entry-file ./index.ios.js --platform ios --bundle-output ios/main.jsbundle
You can just run:
react-native bundle --entry-file index.js --platform ios --dev false --bundle-output ios/main.jsbundle --assets-dest ios
In my case I got this error at archive after updating from RN 0.53.3 to 0.55.4
/Users/<myuser>/Desktop/projects/<myProjectName>mobileapp/index.ios.js: Plugin 0 specified in "/Users/<myUserName>/Desktop/projects/<myProjectName>mobileapp/node_modules/babel-preset-react-native/index.js" provided an invalid property of "default" (While processing preset: "/Users/<myUserName>/Desktop/projects/<myProjectName>mobileapp/node_modules/babel-preset-react-native/index.js")

A big importance to fix this had the line above the error related to babel-preset-react-native
After many hours of trying several workarounds I found a solution by downgrading babel-preset-react-native from ^5.0.2 to ^4.0.0 to make the archive process work.
In my case, it was caused by the javascript code. The error showed at the Metro Bundler(Command Line). Check the Metro Bundler, Does it have an Error or not.
For some people like me this is simply an indication of an error in the JavaScript code. I discovered this to be the case after entering the following command: npx react-native bundle --entry-file index.js --bundle-output "bundle.bundle". Android users would need to specify the platform like so: npx react-native bundle --entry-file --platform "ios" index.js --bundle-output "bundle.bundle".
The bundle failed and the syntax error was shown. Any attempt to open the offending code in a simulator would show the error too.
In my case this was caused by a space character in my project path: /users/USER/Projects/Project HousePlants/
That space in Project Houseplants the bundle can not handle and therefore can not find your main.jsbundle
Make sure that you have no whitespace characters in your path and try again.
See this answer
If properties of config file are changing at run time then make sure there is no error in that as well, if property is not set properly then main.bundlejs would not be generated.
For Example :
isSent:false,
isShow:false
this two properties were setting at run time and found that for a particular record isSent and isShow were not set which made it
isSent:,
isShow:
at run time and caused error.
PFB the command I ran, which resolves the issue.
npm i
cd ios
pod install
Please Make sure you are using same node version in project and xcode
For me i had installed 2 different nodejs versions. when delete one nodejs it was working fine
This is completely stupid, but it happened to me, so I will mention it in case it happens to someone else:
This error occurred on Product > Archive because of a missing dependency.
Changes to package.json were not pushed with the code using the newly added dependency. x)
True story. (facepalm)
Another instance:
import from a JavaScript file that wasn't pushed.
Simply cleaning the project in Xcode helped me

Using React-Native run in Xcode counter an error

I get new version of react-native and when I initialize a new project and run it in Xcode I have the error:(react-native 0.9 IOS run error).
Please help me!
