I am working on Flutter PWA, in the console I am not able to check the error logs (similar to android error logs) after executing the command.
I tried working on VS code and Android studio
How should I check the error logs while developing for Flutter PWA?
print() statement will automatically print the output in the VS code debug console.
To open debug console in vs code goto View->Debug Console or use a key shortcut CTRL+SHIFT+Y
You should Use the print statement and check in run tab not logcat
Example Code :
try{
await FirebaseAuth.instance.signInWithEmailAndPassword(email:_email , password:_password);
}
catch(e){
print(e.message);
}

I installed the flutter in my windows 11. When I open the new flutter project, after installing the flutter plugins, I got this error 'Pub get has not been run '.
I also clicked on get dependences and upgrade dependencies. But still getting the error.
Is there any solution.
This is a known bug in Android Studio. The message disappears, when I disconnect my phone from my MacBook and plug it in again. You could also try to restart Android Studio, use flutter pub get in your terminal or just press ignore.
first of all these errors just appears when i run the app on a real device
the app runs perfectly on android studio emulator
i'm using android studio and Getx package for my flutter project
right after running the app on real device this error appears
E/LB ( 4438): fail to open file: No such file or directory
and after opening the drawer in the app => this error appears
V/MiuiFrameworkFactory( 4438): get AllImpl object = android.common.MiuiFrameworkFactoryImpl#71c94b4
W/MirrorManager( 4438): this model don't Support
and the app doesn't change to the dark mode when i press the change theme button i made
anyone can explain these errors for me , and how can i fix this ??
I upgraded Flutter to 2.0.0 recently and am stuck with this issue. flutter run and flutter run --profile work perfectly well, but flutter run --release makes app crash after startup. There is no stacktrace, there is no error or warning, there is no build issue or verbose warning, no hint really. I googled a lot, but similar questions were answered like "try to remove this line" or "try to add that line". I couldn't find any clear steps on how to debug what's wrong.
What steps should I take to debug this issue and find the root cause instead of trying meaningless changes on code hoping some of them will eventually fix the issue?
Use adb logcat
OR
Enable debugging in release build, by modifying your android/app/build.gradle
like this
buildTypes {
release {
debuggable true
shrinkResources false
minifyEnabled false
...
}
}
When the error is code related and not in flutter itself sentry should help.
Sentry's Flutter SDK enables automatic reporting of errors, messages,
and exceptions.
You can import it just as any other package
dependencies:
sentry_flutter: ^4.0.6
and configure it as early as possible in you app
import 'package:flutter/widgets.dart';
import 'package:sentry_flutter/sentry_flutter.dart';
Future<void> main() async {
await SentryFlutter.init(
(options) => options.dsn = 'put_your_public_key_here',
appRunner: () => runApp(MyApp()),
);
}
To get your public key you just have to sign up on sentry.io and create a flutter project, no need to search for your key your it should be in the example code, it wont let you pass that point without initialiting it so you can't miss it.
The docs regarding flutter can be found here.
You can Use Firebase Analytics to see error logs from your released devices from firebase. Previously it was named as Fabric.
Or you can create your own log tracker, write the logs in a file and upload the log to your server.
You can give options to user to capture log and send to server within "Advanced Settings" or something like that.
try this flutter run --release --no-shrink
Check if you have given correct permission to the app in AndroidManifest.xml, in my case I simply fixed this issue by giving camera permission
<uses-permission android:name="android.permission.CAMERA" />
before the tag
In my case, after two day of confusion because app crashes only in release mode without any error on console, and errors shown in adb logcat not clear (unknown errors), after that I switching Flutter channel from stable to master, after run release on master channel errors started shown as clear messages, I solved these errors then crashes problem solved.
So my steps is:
1- Switching Flutter channel to master by run this command in terminal:
flutter channel master
2- Run upgrade command in terminal:
flutter upgrade
3- Run app as release:
flutter run --release
4- Watch console to see errors...
I'm launching the app in a real device.
Anyone knows why this is happening?
Launching lib/main.dart on GT I9063T in debug mode...
✓ Built build/app/outputs/apk/debug/app-debug.apk.
Error waiting for a debug connection: Bad state: No element
Error launching application on GT I9063T.
Exited (sigterm)
Even the hello-world app is showing this error.
Run flutter clean.
This works for me.
I had this error with a clean install on MacOS X (Mojave), and after trial and error discovered that the main user who is running flutter debug needs to be an admin user.
Clue was the line:
log: Must be admin to run 'stream' command
when running from command line.
After this VS Code and command line work.
Build always works on my VS code normally. Updating to the latest Flutter 1.12 also started showing this and most times, my code either shows up on my device first before showing that debug has started or the program just quits. Any fix with VS code because I am not an Android Studio fan.
Try to change flutter channel to beta using "flutter channel beta". it worked for me to fix issue which is because flutter version is updated to "v1.12.13+hotfix.5".
I ended reinstalling flutter sdk.
Ubuntu 16.04
VSCODE
Started with Flutter 12. It seems that the user must be admin now.
Rolling back to a previous Flutter version will do for now.
flutter version v1.9.1+hotfix.6
I changed the channel of flutter to the master and works, I was using the stable channel.
You can use the command:
flutter channel master
or just flutter channel to see another channel.
In the 'Developer Options' of my phone, when I changed the 'Select Debug app' option to 'Nothing', the error was solved.
Try to downgrade the libglvnd package to version 1.2.0 in arch linux.
This started occuring after i updated xcode to 14.1.
Simple Restarting mac works with flutter clean
when i create a new flutter project in vscode it will immediately shows an error in the main.dart file and gives a gradle error when trying to debug.
shown here: main.dart error
"compiler message: lib/main.dart:68:19: Error: Too few positional arguments: 1 required, 0 given."
I've reinstalled dart and flutter plugins. updated the java install.
in debug console i get this:
debug console
added output of flutter doctor -v
enter image description here
I was also facing the same error, but it was always on my test folder.
This is what I did:
On your terminal, make sure you are in your project repository.
Run the flutter pub get command, it worked for me, may be you
should try it too.
Do you possibly have two different versions of the Flutter SDK on your machine? I wonder if one is being used by flutter create and the other for analysis.
If you're sure you only have one, please open an issue on GitHub and attach a log file for me to investigate.
