I'm debugging a code but every time I try to see the variable values it shows this message. does anyone know how to resolve?
Flutter 3.3.10 • channel stable • https://github.com/flutter/flutter.git
Framework • revision 135454af32 (5 weeks ago) • 2022-12-15 07:36:55 -0800

google chrome version 109.0.5414.75 64 bit
I searched the internet and it was telling me to update flutter to a version greater than 3.0 and google chrome to the newest version and even so it continues to give this error. I tried to run the project in another browser but the same error message appears. in short, none of the solutions I've found to date allowed. I even formatted the computer and today I have Windows 11
• Name: WebApp1
• Publish: Code
• Runtime stack: Java 11
• Operating system: Linux
• Continuous deployment: Disable
You need to ensure that you can integrate WebApp1 with GitHub Actions.
Which setting should you modify?
Here is how the default configuration for tests looks like:
In Flutter Drive arguments we can see that there is a target defined
drive --target=test_driver/main.dart
Flutter documentation on integration tests doesn't mention creating this file. So this folder with the respective file is missing in my project, which logically results into fail:
Target file "test_driver/main.dart" not found.
Here are the logs:
> flutter devices
3 connected devices:
Android SDK built for x86 (mobile) • emulator-5554 • android-x86 • Android 10 (API 29) (emulator)
macOS (desktop) • macos • darwin-x64 • macOS 12.4 21F79 darwin-x64
Chrome (web) • chrome • web-javascript • Google Chrome 103.0.5060.114
> flutter -d emulator-5554 drive --target=test_driver/main.dart
Target file "test_driver/main.dart" not found.
The documentation on how to write integration tests only mentions test_driver when testing web.
Apparently I am either missing stuff in my project or I need to configure codemagic workflow differently.
There is a bit information here https://docs.codemagic.io/yaml-testing/testing/ for yaml configuration. Should i switch to yaml config, or can it be done from CodeMagic UI?
UPDATE:
After I have change the configuration as mentioned in the answers to this:
The logs are now:
Test file not found: > /Users/builder/clone/test_driver/app_test_test.dart
The recommended approach per Flutter documentation is to use:
flutter test integration_test
Thus, in the arguments section in Codemagic, just add test integration_test.
test_driver/main.dart is just a placeholder. Flutter documentation covered this in step 3. Create the test files
And in Codemagic you need to specify drive --target=integration_test/app_test.dart
I want to setup Flutter to web-development and so I followed these instructions (Link to Flutter web setup):
$ flutter channel beta
$ flutter upgrade
$ flutter config --enable-web
$ flutter devices
The output should be the following:
2 connected device:
Web Server • web-server • web-javascript • Flutter Tools
Chrome • chrome • web-javascript • Google Chrome 81.0.4044.129
The problem is that my output doesn't contain the web-server:
2 connected devices:
Chrome (web) • chrome • web-javascript • Google Chrome 88.0.4324.150
Edge (web) • edge • web-javascript • Microsoft Edge 88.0.705.68
Can you help?
While web-server is not listed in flutter devices it's still available. We don't list it any more because it's always available, so there's no need to check for its existence. This is unlike a phone that needs to be connected via USB and configured to accept debug connections, or emulator/simulator that needs to be started outside the Flutter tool.
There are many similar questions out there, but none of them help (for instance, this question is well upvoted, with a well upvoted answer, and would seem to be a dupe. BUT like others who commented there, the answer did not help me (also, the answer is 2 years old, which is an eternity on Flutter)).
At most, they tell how to add an Android VM in Android Studio. I have done so:
They also suggest setting the environment variables ANDROID_HOME and/or ANDROID_SDK_ROOT. I have set both to the same value:
C:\Users\me>dir %ANDROID_HOME%
Volume in drive C is Windows
Volume Serial Number is FE0C-16F0
Directory of C:\Users\me\AppData\Local\Android\sdk

When I create the default Flutter app, Android Studio shows me the VMs as an option for run/debug:
BUT, when I open that same project's folder (or any other) with Visual Studio Code and run, it launches in the Chrome browser, because:
PS C:\Users\me\AndroidStudioProjects\flutter_app> flutter devices
3 connected devices:
Web Server • web-server • web-javascript • Flutter Tools

PS C:\Users\me\AndroidStudioProjects\flutter_app>
How do get Flutter to recognize my Android virtual machines?
I can see that each has a sub-directory in c:\Users\me\.android\avd. How do I make Flutter aware of it?
Here's the output of Flutter doctor, for completeness:

This is interesting: when I run a Flutter app in Android Studio, its VM suddenly becomes visible in Flutter/Visual Studio Code:
PS C:\Users\me\AndroidStudioProjects\flutter_app> flutter devices
4 connected devices:
sdk gphone x86 arm • emulator-5554 • android-x86 • Android 11 (API
30) (emulator) Web Server • web-server • web-javascript •
Flutter Tools Chrome • chrome • web-javascript •

web-javascript • Microsoft Edge 83.0.478.54 PS

When I stop the device in Android Studio, Flutter can no longer see it.
I highly suggest that you use Git to install Flutter, then install the Android SDK with Android Studio. Don't forget to add Flutter/bin to your PATH. Then create your Virtual Device in Android Studio and it should show up in Visual Studio Code and the console.
Run your virtual device in AVD manager
Then while it is running go to your flutter.console terminal
Try flutter doctor in terminal see if the device show in the list
To see Devices: show devices in terminal
if device is visible navigate to your flutter project.
in my case: C:\Users\husmi\StudioProjects\testapp
and in terminal type 'flutter run'
It worked for me!!
flutter console
command in flutter console
