I believe my Flutter SDK version is being erroneously reported and do not know where the conflict is.
When running flutter doctor it reports Flutter 2.2.3 • channel stable. However, the bottom toolbar in VSCode displays Flutter: 2.0.4.
Is there a reason VSCode and terminal would report the Flutter version differently? And how can I ensure I am running the correct SDK version?
Look into "dart.flutterSdkPath" setting in vscode and change if needed. The problem could be with you having multiple versions of Flutter on the disk and auto-find fails to find the correct one (last version), manually override.
In my case my path( environment variables) of SDK was set wrong check yours first
and if still not worked try running commands
Flutter clean
Flutter upgrade

Warning: `dart` on your path resolves to /usr/lib/dart/bin/dart, which is
not inside your current Flutter SDK checkout at /home/ankit/flutter.
Consider adding /home/ankit/flutter/bin to the front of your path.
This exception started when the flutter was updated. How do I solve this?
The Problem:
This is happening because you have a separate installation of Dart on your system. The Flutter SDK includes and manages it's own dart SDK, but you can use the dart SDK separately.
Why it Matters
Flutter recommends that you use the dart SDK included with Flutter because Flutter manages it - It will automatically use and upgrade supported versions when using the flutter upgrade command on your terminal, and during initial install.
Flutter is noticing that you have a dart SDK install that did not come with the Flutter SDK. It's giving you a warning because of the possible differences in versions (and possibly other configurations) that could prevent an optimal flutter development experience.
System Path
Here's an explanation of path. You will probably need to set your path environment variables to get the whole fix.
This link shows the official Apple guide to working with the terminal environment variables (including path) but a quick google around should help you find any answers you can't find here.
The path resolves from "front" to "back" - meaning that if the executable in question occurs twice, it will grab the first one. Flutter doctor wants you to add the flutter dart path at the front so that subsequent dart calls will resolve to the Flutter Dart SDK.
The High-Level Solution
Unless you're doing dart development outside flutter, you don't need an additional dart SDK. Most of the time the Flutter dart SDK will work for cases besides flutter as well.
I would recommend removing your other dart install, and using the dart install that comes with flutter. This process will vary depending on how you installed the other dart SDK.
TLDR/Quick Fix
based on what you provided, run this on your Zsh command-line:
export PATH="/home/ankit/flutter/bin:$PATH"
It will only work until you restart your computer.
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.
FVM Flutter Sidekick
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
pubspec.lock screenshot
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
sdks:
dart: ">=2.10.0-110 <2.11.0"
flutter: ">=1.16.0 <2.0.0"

Worked for me on beta as well. It's a bit less cutting edge than dev so might be better for some uses.
flutter channel beta
flutter upgrade
Also found out that turning off the previewLSP setting in the VSCode Dart & Flutter extension settings turns the refactoring menu back on. There seems to be a disagreement between LSP mode and refactoring that is fixed in later versions. If you don't want to upgrade you can try turning that setting off and then restarting VSCode.
Run flutter doctor, if flutter and dart are up to date then try switching to a different flutter channel and update flutter and dart again. It worked for me recently.
Try switch to dev channel,
flutter channel dev
flutter upgrade
I sugest to re-install the flutter plugin for VSCode (wich includes dart). See if it helps.
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
