After running flutter pub upgrade my app stops running

I started getting this error immediately I ran flutter pub upgrade, I have tried the solutions here but it is not working for me, I have also ran
Flutter clean
Flutter pub get
Deleted and install new flutter
any help will be really appreciated
NOTE I'm using an M1 Pro MacBook.
Yes its most probably you are using a package that is not yet compatible or does not match with required compileSdk version.
To identify which package is causing the issue, maybe you can try to revert your pubspec to when it was working and upgrade your packages one by one.
I'm also using M1 Macbook, so if you need further help, let me know.
Try this,
from top menu bar select Tools -> Flutter -> Flutter clean
Open pubspec.yaml & execute pub get & run again your code
Thanks guys for your help, I have finally solved the error from the accepted answer here

Initializing Flutter. This may take a few minutes

first post (sorry for noobish post). I've searched Google and all over StackOverFlow to solve the above query on VSCode but to no avail anybody that can help solve this error I'd be really grateful!
It just keeps loading with the following message: Initializing Flutter. This may take a few minutes.
Issue of error
This seems to be a issue with the Flutter installation, please make sure to delete your Flutter folder (the one you downloaded from the GitHub repo) and follow
these instructions for your platform, step by step.
It seems like you was upgrading your flutter but due to some reason its not completely upgraded. I think you should try again to upgrade your flutter
Try running flutter in the terminal. If there are any flutter or dart upgrades pending, this will check them and finish those. Then run a flutter doctor, just to make sure everything is running fine.
If you run the the following lines in the CMD:
flutter channel dev
flutter upgrade
and it kept downloading till the message
Running pub upgrade...
then Close the CMD and for the message
"Initializing Flutter. This may take a few minutes"
Upgrading will actually take place in the Ide till it finishes
that's it :)
I thinks replace folder flutter with download new flutter version can cut off time initializing flutter.
I tired waiting initializing by "flutter upgrade"
It is due to flutter upgrade. flutter upgrade is for upgrading your existing version of flutter.
So, Don't worry. This will take 5-10 minutes to upgrade. After you will be getting the updated flutter upgrades.

Parameter format not correct - flutter run

Even when I run a new project in my device or emulator, during Assemble debug process a message appears in Debug Console 'Parameter Format not correct', but the app seems to run properly.
when I add 1-2 dependencies/ plugins, countless redlines occurs in Debug Console...
I don't know what is the reason and solution.
Sorry guys this happens every time you run a project build by the previous version of flutter... and this error is not a big deal... dont worry...
I have also faced the same issue. It started coming when I upgraded the flutter SDK to version 1.17.3. The easiest solution I can come up with is to downgrade the flutter SDK.
If you are using VS code then you easily switch between flutter SDKs from the bottom bar.
To add flutter SDK -
Goto file -> settings -> flutter SDK -> Add item
then you can give the path of other SDK.
If you are not using the VS code, change the path of SDK from environment variables.
If this doesn't work out, try changing the drive for SDK of flutter and android both.
Example- From D:\flutter to E:\flutter. I have not tried this but for my friend, it worked.
If none of these workes, just ignore this error. They might fix this in future upgrades.
it may be possible ,you have cloned the repo from github and trying to run on your local machine. just change the compileSdkVersion in android>app>build.gradle file, i was facing this issue and get it fixed now
android {
compileSdkVersion 30
}
I had the same issue, but it was fixed by running flutter doctor --android-licenses
I had the same issue try to change Your Environment variable path
If you're using VS Code, then you can try this process: Go to Settings -> Flutter SDK Paths -> click on Add Item. Then put the Flutter SDK location from your drive.
For example: C:\Flutter\flutter_windows_2.5.2-stable\flutter.
I hope it worked!!
Same problem, but it was fixed by running following command in terminal.
flutter doctor --android-licenses

Looks like the bin/flutter file was corrupted due to permission issue. You may need to reinstall flutter SDK to fix the issue as your flutter bin file is missing.
Here is the installation manual: https://flutter.dev/docs/get-started/install

Flutter 'cannot find symbol'

What can I do to fix this issue, when trying to debug on android phone OR emulator?

Ive tried reinstalling whole flutter, and still the same issue.
the project is on flutter version 1.7.8. Tried going to latest versions, still the same.
Try running flutter clean to clear the build artifacts - If the project was copied from another computer, or if you were using different version of flutter, that could help.
