I have followed below url and enabled web for my flutter application.
https://flutter.dev/docs/get-started/web
flutter channel master
flutter config --enable-web
flutter create .
flutter run -d chrome
flutter build web
Everything went well and I am able to launch my application on Web. However, after enabling web my ios simulators not appearing in devices list.
flutter devices
2 connected devices:
Chrome • chrome • web-javascript • Google Chrome 80.0.3955.4 dev
Web Server • web-server • web-javascript • Flutter Tools
Could someone help me to resolve this issue?
Here's my environment:
flutter --version

As discussed here https://github.com/flutter/flutter/issues/44326 I have updated my xcode from 9.4.1 to 11.2. Now the issue is fixed and I am able to see all devices.

Recently I've joined a project of a flutter app using firebase, and everything was fine until it comes to make the production builds. For Android it works fine. But for ios I'm facing a problem that in the simulator it runs without a problem but when I uploaded it to Testflight for my coworkers to test it immediately crashes when opened.
That's my flutter doctor -v:

I've already tested some things that I found googling, like add the Google-Services.plist again using xcode and verified if the schemas to the archive were pointing to release mode. But none of them worked.
If any additional data is needed, I'll be glad to provide. So thanks in advance for any help.
Well, I found the error. I had changed the Flutter version using git (thus, the Flutter folder is a git repository). When I changed the version, it left the cache from the other Flutter version, and that cache was causing the problem.
One thing that helped me to find this out was running the release build in a physical device using Xcode; there it prompt me the following error:
Error while initializing the Dart VM: Wrong full snapshot version, expected '9cf77f4405212c45daf608e1cd646852' found 'e4a09dbf2bb120fe4674e0576617a0dc'
And for that, I found a solution on the web. What I did was to remove the folder cache inside <yourFlutterDir>/bin and run the following commands in the Flutter directory:
git reset --hard
git clean -xffd
flutter doctor
And then, I went to my Flutter project folder, ran flutter clean, and finally flutter build ios.
So the project built successfully, and the app worked in iOS.
I want to upgrade my project which is on Flutter 2.0 to the latest version of flutter (2.5).
I have already seen this question which is most relevant.
How do I upgrade an existing Flutter app?
In my Mac, I have Flutter upgraded to 2.5. You can see the output of flutter doctor -v below:

I have searched over the internet about it. Mostly, I see two things, either how to upgrade to null-safety (which means from earlier versions to 2.0) or how to upgrade Flutter sdk in your system.
I have tried running flutter upgrade command which says I'm up-to-date.
I have also tried running flutter pub upgrade.
Both do not change the version of flutter in the pubspec.lock file inside my project which says at the end of file:
sdks:
dart: ">=2.14.0 <3.0.0"
flutter: ">=2.0.0"
Please guide me how can I upgrade my project to the latest version.
Thanks in advance :)
The Flutter project will have the same version as your system does. If you have the latest Flutter version on your system, then the app built from that system will have the latest version.
For example, if your system has Flutter 2.8 (latest while answering) and you build an app through it, your app is based on 2.8.
You're using flutter: >=2.0.0 which basically tells your app to use 2.0.0. Usually using the flutter sdk constraint is only used in plugins. It's okay to leave this out, if you remove flutter: >=2.0.0 it will automatically use your SDK version
After updating my iPhone 11 to iOS version 14.7.1, my flutter app is not launching anymore.
Steps already performed:
flutter clean
flutter pub get
flutter run
Also,
uninstalled and reinstalled the app
restarted the phone

Is anybody facing the same issue? Any idea how to fix this?
Thank you
You have runtime error just before your first screen renders, try putting breakpoint in the first line of the main and debug line by line.
I was able to fix the issue. It seems to be a random issue that happens time to time when updating either the flutter version or iOS...
Here's how I fixed the issue:
==>> you can also get inspired by this thread: https://github.com/flutter/flutter/issues/72161
However, what worked for me was very simple as I am using vs code:
uninstalled the app
restarted the phone
open the app using Xcode
Product -> Clean Build Folder
Product -> Run
The app will launch correctly, then quit Xcode
After that, I run the app using vs code, and now it works as before.
I wrote a Flutter app which connects to a web server running on a separate machine using the dart http package. On my local machine (Mac) I added the hostname 'www.xyz.com' to /etc/hosts and everything works fine when using the IOS Simulator. I would like to test the app on a real device (iPhone SE) but don't want to jailbreak the device. Because it's not possible to edit the hosts file on the phone without jailbreaking it, I installed Weblock which allows to setup redirect rules. I am able to start the app on my phone, however, when making a request to the web server on the separate machine (in my local network) I get the following error:
SocketException: Failed host lookup: 'www.xyz.com' (OS Error: nodename nor servname provided, or not known errno = 8)
From outside the app I can access the web server via 'www.xyz.com' in my browser.
To summarize:
App running in IOS simulator on machine A and connecting to web server on machine B -> works fine
App running on real device and connecting to web server on machine B -> error
Connecting to web server on machine B via browser on Phone -> works fine
Output flutter doctor -v

I'm having issues setting up push notifications for iOS on Flutter.
Another dev tried adding too - had the same problem.
TL;DR: Can anyone get pushes running on iOS Flutter with clean new build from stable channel?
I followed setup steps described here:
https://pub.dev/packages/firebase_messaging
Specifically:
Generated app ID and push Key in https://developer.apple.com/account/resources/certificates/
Added info.plist to ios/Runner folder
Turned on Push capabilities
Uploaded APNS certificate to Firebase console
Made sure bundle ID is the same in App / Runner, info.plist and GoogleService-Info.plist
Added lines in AppDelegate.swift
if #available(iOS 10.0, *) {
UNUserNotificationCenter.current().delegate = self as? UNUserNotificationCenterDelegate
}
Pushes aren't coming. Neither when app in background, not at all.
I also tried another step - sending individual push. Send code in CURL looks like this:
curl -i -X POST \
-H "Content-Type:application/json" \
-H "Authorization:key=AIza_legacy_key" \
-d \
'{
"to": "my_push_token",
"notification":
{"body": "test_body",
"title": "test_title"
},
"priority": "high",
}
' \
'https://fcm.googleapis.com/fcm/send'
And the response is always this type:
- First request is InvalidRegistration
- Second and next same calls is NotRegistered
Another person found similar problem this summer and posted on GitHub, but thread was closed:

p.s. Some things I've tried:
Used another developer account (100% confirmed pushes are working on another project)
Used another Firebase account
Recreated certificates, projects
Gave to try another developer to setup pushes his own (he also confirmed to be successfull in the past).
Magically things just started working yesterday evening.
So first - just try now. If not working - recreate certificates and redo initialization steps. If still not working - pray and retry another day.
