When I start debug my flutter(2.0.1) app in Android studio 4.2, the app start and crashed. there has no error log output, what should I do to find why the app crashed? this is the startup log(no error message):
This will generate a JSON format file containing all messages that
need to be translated.

I use flutter on window 10, when i run flutter on console and perform flutter run -d chrome, the error is waiting for connection from debug service on chrome. The error from chrome page show "The connection cant be reach".
My flutter doctor show i didnt install Visual Studio, but i already used to the Visual Studio Code. Is it a must to install Visual Studio ? Other than that, everything is passed.
I try to run the app on Visual Studio Code, the error is the same. Even on edge, on web-server. The error is the same.
I try to add Dart Debug Extension on Chrome but cannot be enable. Can some help ?

The problem can be solved by performing the following actions
Upgraded flutter to latest version
Reinstall android studio
run flutter pub upgrade --major-versions
upgrade your chrome to latest
if you are using any extension in VS code to run flutter then there is also a possibility that the extension is not working properly try to change the version.
If it works give me a upvote,I'm new here.
I am using biometric_storage ^4.1.3 for my flutter app and it compiles for Android and Windows.
Before installing biometric_storage it compiled for Linux as well, but now it throws a clang error due to undefined reference to g_task_set_name (a glib function) in libsecret.

Edit 1:
I am able to use flutter_locker package for now. It only supports mobile platforms.
I am having an issue in experimenting with flutter integration tests. My goal is to be able to run headless tests for training purposes (a student produces an app, that I will test automatically). As it runs on servers it has to be headless and as quick as possible, so I chose chromedriver (I am not sure this is the best choice though, if you have other ideas please feel free to tell me).
I followed the tutorial here: https://flutter.dev/docs/cookbook/testing/integration/introduction
I created an empty project, filled lib/main.dart, test_driver/app.dart, test_driver/app_test.dart and pubspec.yaml exactly as suggested on the link above.
Then I tried to run this command:
flutter drive --target=test_driver/app.dart
Everything works properly, all tests passed
Then I launched chromedriver with chromedriver --port=4444 and tried to launch the test on chrome as suggested in the tutorial:
flutter drive test_driver/app.dart --browser-name=chrome --release
In this situation, after some time chrome opens and immediately crash ("Application finished"), juste before app_test.dart is launched:

Application finished.

Then the tests hang here forever until I kill it manually. Adding the "-v" flag does not give more information on why the application itself has finished:

Can anyone help me here on how to debug this situation ? I must admit that I am stuck.
Thanks a lot,
PS: I would also like to output the results of the drive test in JSON format, as you do with flutter test --machine ..., but I can't find a way to do it with flutter drive ..., so if anyone has a clue please tell me, otherwise I will open another post.

I had the same issue. After two days of debugging I have just found out it was caused by one of my dependencies. It is firebase_auth package version 1.1.3.
As I can see the issue is resolved in firebase_auth 1.1.4 released on 10th of May 2021.
So just update to firebase_auth 1.1.4 if you use this package
I faced something similar a few days back.
There can be two possibilities why it is happening :
You have not granted permission for something you are trying to access (like getting the location/camera ). If this is the case then read the docs of the package you might be using and add the permissions programatically.
Sometimes our podfile reference gets corrupted. (This is what happened in my case). For this delete your podfile.lock file (ios/podfile.lock). For a fresh start you can also delete your pubspec.lock as well. And then do a flutter pub get or simply run your app.
I can not use these both flutter plugins together:
cloud_firestore: ^0.9.0+2
barcode_scan: ^0.0.8
When run, error occured:
D8: Program type already present: android.arch.core.util.Function

it compiled and runned on Android phone when I remove one of them. But both can not go together. How to fix?
In short
Add multidex library to android app dependency (/android/app/build.gradle)
...
android {
...
defaultConfig {
...
multiDexEnabled true
}
...
}
...
dependencies {
implementation 'com.android.support:multidex:1.0.3' // use latest version
...
}
...
under android directory
gradel.properties file
Add
android.useAndroidX=true
android.enableJetifier=true
Found the solution (for me, at least) !

It seems that runner version 1.2.1 was the responsible for this !
After I changed to version 1.2.0 it worked.
So, I changed the following line from android/app/build.gradle
androidTestImplementation 'androidx.test:runner:1.2.1'
to
androidTestImplementation 'androidx.test:runner: 1.2.0'
(Note: Also, don't forget to add in Firebase Console all SHA certificate fingerprints you are going to use in your apps.)
Report an issue with barcode_scan to have it updated for AndroidX.
Limit the plugin to a version that does not depend on AndroidX until a new barcode_scan version becomes available:
cloud_firestore: ^0.8.2
Or update barcode_scan manually like mentioned in
https://github.com/flutter/flutter/issues/28207#issuecomment-465600796
