How can i fix the versioning issue ?
As it says, you need to upgrade dart SDK to the latest version by running the command flutter upgrade. Make sure to backup your project

I have an old version of flutter.
I would like to update the version but not to the latest. I tried the command
flutter upgrade
and then
flutter downgrade 3.3.1
but it only returns me to the version I had previously and not to an intermediate version between my old one and the latest version available.
What can I do?
Thank you.
To downgrade to a specific version of Flutter, you can use the following command:
flutter upgrade --force-downgrade -v enter your version here
Replace with the version number you want to downgrade to (e.g., 3.1.1). The --force-downgrade option is necessary as it allows you to downgrade to a previous version of Flutter.
I want to upgrade flutter specific version. How to do , i don't want to upgrade latest sdk version. I want tp upgrade specific sdk version
There is an issue about your question on Github. I think it is not possible yet.
enter image description hereenter image description hereToday VS Code sent me an error:
Version 2.16.1 of the Dart SDK is available (you have 2.16.0). Some features of Dart Code may not work correctly with an old SDK.
Do I have to download it again as ZIP and add it to PATH for the update?
It should work with
flutter upgrade
You can upgrade from Extensions from VScode
For linux try this,
flutter channel stable
flutter upgrade
or this
flutter channel master
flutter upgrade
I have some older projects built on flutter 1.22.6 and now I am working on latest version of flutter but there often comes need when I've to work on previous projects non null safety one's so when I try to downgrade flutter by giving command flutter downgrade 1.22.6 it tells me to downgrade to 2.5.2 and if I try to switch channel and then downgrade it downgrades to 2.5.2 first and then tells there is no version related to 1.22.6. This method used to be working before but now its not working anymore. I don't want to download zip files and then replace again flutter every-time I just want it to be done by cli.
My OS is windows 11
You can use flutter Version Manager fvm its specifically made to control flutter versions plus along with that you can install flutter sidekick as well. I am attaching link for you.

Since you can no longer downgrade flutter versions, I have found the best way to do this is:
Download desired flutter version
Locate current 'flutter' folder and replace it with the desired version
if you run --flutter version after, it should show the correct version
Where can I see the flutter version used in a flutter project? Is there a file inside the project directory where I can see it? I think it is not specified inside the pubscpec.yaml file
So far, I think the specific version can not be found but only what versions can be used in a project. It can be found at the bottom part of pubscpec.lock file

It will not show version project wise. It will overall flutter version that you have installed in your system. For that:
Open your flutter project root directory in Command Prompt or Terminal type:
flutter --version command.
After typing the above command hit enter and You’ll see it will display us the currently installed flutter and Dart version in your computer and also tells us which version type we have installed like Stable or Beta.
Note: There is no such feature/command to check about which version of flutter you have used in Specific project.
Check this thread it will give you more idea:
https://github.com/flutter/flutter/issues/14230
All projects you run will use the flutter sdk installed in your machine/computer from where you specified its location from. So if the version the project uses don't match with the version you've and they conflict, you will have errors and if there is a huge gap and breaking changes, you'll need to either upgrade or downgrade the sdk. But most of the time, things are deprecated before they just become breaking changes and so you shouldn't have big issues. So the best thing to do is usually to upgrade. First check your sdk version via flutter --version. If its outdated, use flutter upgrade to upgrade it.
You can either run flutter --version to check flutter version installed on your machine or check it in your pubspec.lock file for current flutter version in your project
