Flutter keeps getting stuck in "Syncing files to device" when installing app on a real iOS Device.

[real1900]

I see :

Running Xcode build... Xcode build done. 426.0s Installing and launching... Waiting for Suleman’s iPhone to report its views... Debug service listening on ws://localhost:59585/ws Syncing files to device Suleman’s iPhone ...

Flutter doctor shows:

Hi @real1900 Can you please provide your flutter doctor -v, your flutter run --verbose and your pubspec.yaml. Thank you

My app works fine with flutter run --verbose but it doesn't work with the debug button in android studio which lets me to use break points

[sommestad]

Same thing happens to me. Occasionally I get it working again by deleting the app from the phone and running flutter clean but even that is only working intermittently...

Hi @real1900 Are you able to reproduce the issue by running flutter run --verbose? Are you using VScode or Android Studio?

[bazinac]

Hi, hitting this as well with Android Studio on Mac.

With flutter run --verbose, it usually deploys fine.

[real1900]

I am running Android Studio

[real1900]

I also get the same behavior with VSCode

[pedromassangocode]

I noticed that you was running on a physical device, are you having the same issue using a simulator? What is the OS version of the device you are having this issue?

[dodatw]

I also get the same behavior with Android Studio. But I only can reproduce when Run debug by IDE. If run by "flutter run -v", seem no this issue. BUT, I saw this log, I don't know if helpful. (app can use, bug log stuck at "Updating files.")

[  +65 ms] Updating files
[+239030 ms] Error writing "build/flutter_assets/images/btn_setting_n.png" to DevFS: HttpException: , uri = http://localhost:57657

Note: the "file path" different every times.

[hossam-zaki]

I have this problem as well. I do not get this issue on the simulator, but I do when running on an external ios device. I also get this issue on VS code

[pedromassangocode]

I’m unable to reproduce the issue to pinpoint the cause, but there are reports from several users. The issue needs further investigation.

[dodatw]

I think it should be same issue, https://github.com/flutter/flutter/pull/66152

[hossam-zaki]

@pedromassangocode They way it messes up for me is that I connect my phone (iPhone SE first gen running iOS 13) to my computer. I do flutter run -d all and it doesn't work for me at all. I would really appreciate someone to look into this or try to reproduce it as well because it's a pain to always use the simulator, especially with regard to features like camera, texting, etc...

[pedromassangocode]

Hi @hossam-zaki Please file a new issue for this and completely fill out the template. We don't track more than one problem in a GitHub issue as they may be duplicates of different existing issues, or may need different teams to look at them.

[pedromassangocode]

Updating title since this seems to be happening on VS code as well.

[jmagman]

I agree with @dodatw, this looks like a duplicate of https://github.com/flutter/flutter/issues/65402

This should be alleviated with https://github.com/flutter/flutter/pull/66152, which is available on the master channel, and was just hotfixed to the beta channel (it's kind of weird but it hasn't made it to dev yet, but it will be there soon).

[AriesL-ux]

Hi all,

I had the same situation today, and took me a few hours to find out the solution, and it was very simple.

I basically started building a loop, then got distracted with something else, and forgot to delete it.

So what caused my "Syncing files to device" not to finish, and my initial page to freeze, was this. I had an infinite loop in my Home initState.

Hope this helps someone.

This hot reload issue is still happening. It happens only on iOS device and iOS Simulator for me. I tried both Intel Mac and M1 Mac. I am using flutter 2.2.1. I have tried it with flutter 2.2.0. Same behavior.

Android device and Android Emulator are working fine with hot reload.
