flutter run --machine outputs "event sent after app closed"

[DanTup]

When running flutter run --machine, initial progress messages (if pub get runs) are output with an error:

danny@Dannys-MBP flutter_hello_world % /Users/danny/Dev/Google/flutter/bin/flutter --suppress-analytics run --machine --target lib/broken.dart -d flutter-tester --track-widget-creation --dart-define=flutter.inspector.structuredErrors=true --start-paused --web-server-debug-protocol ws --web-allow-expose-url 

event sent after app closed: {id: 0, progressId: null, message: Running "flutter pub get" in flutter_hello_world...}
event sent after app closed: {id: 0, progressId: null, finished: true}
[{"event":"daemon.connected","params":{"version":"0.5.3","pid":20044}}]

Because this isn't valid JSON, in VS Code we assume this is a message for the user and show it in the debug console (rather than showing a progress indicator).

(@jonahwilliams sorry! 😬)

Also seeing this in Android Studio

I also saw it on Android Studio. I think updating dart and flutter fixed it, but not sure

Yes, we're seeing this in IntelliJ as well:

I believe some refactoring of the logging meant that we can no longer send progress events from the flutter tool early in the app's lifecycle. I have a local change which largely addresses this (but am not certain where the best place is to put a test). I'll follow up with a PR.

fixed by #65508

I got this error too. Need to kill the dart.exe and then close the editor and reopen it

internet connection make me received that error

I use a Mac and I found that the problem was linked to the location I had the flutter SDK installed.

I had it installed in Applications and usr/local/bin which seemed to require authentication/sudo to modify. So, I created a new folder in the home directory called ~/Developer/Resources and unzipped the file there, updated the path in the terminal profile and when I ran it again from android studio / vscode / terminal it downloaded the iOS tools, and worked.

Here are the updated steps for you:

1. Download flutter zip
2. mkdir ~/Developer
3. mkdir ~/Developer/Resources
4. cd ~/Developer/Resources
5. unzip ~/Downloads/flutter_macos_1.22.5-stable.zip
6. nano ~/.zshrc
7. Add export PATH=$PATH:~/Developer/Resources/flutter/bin
8. source ~/.zshrc

Then open project and run.

Why can't it be installed through Homebrew, automatically setting PATH variables correctly etc like normal software does.

@stock-dd Have a look at #14050 for discussion on that topic
