Dart version in Android and Flutter engine is different - flutter

My Flutter Engine using Dart version 2.5 whereas the dart in the android studio seems to have Dart 2.6.1.
Is that any potential issue while developing any project?
How can I ensure that both are same? How can I downgrade the version, please?

Don't worry about that. Flutter will keep using its own Dart version.
The other one will be used when running Dart scripts from CLI.

Ubuntu | Flutter Doctor: dart is not in you current flutter SDK

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.

MapBox crashes on the latest Flutter version

MapBox map isn't working on the latest Flutter version (Flutter 3.3.2, Dart 2.18.1), but it works for my colleague but he is using v3.3.1. and Dart v2.18.0
How can I downgrade to that version?
When I do flutter downgrade v.3.3.1 in the terminal, it wants to downgrade to the previous version that was used, and for me, that was v2.8.1, and I can't seem to upgrade to a specific version, tried switching channels, but it didn't help.
And the problem is definitely in Flutter version.
Any ideas on how to upgrade(or downgrade) to a specific version?
Or maybe you have an idea why MapBox is crashing?
use FVM it will help to choose different flutter versions for different projects, so you can test different flutter versions

Flutter: changing dart SDK

I want to change my sdk version from 2.16.2 to 2.17.1 while I'm using android studio (for a single project only)
could someone please help me with this issue?
Thanks
From File>Settings>Languages&Frameworks>Dart,
Check box - Enable Dart support for the project,
Specify - Dart SDK path
Download the respective Dart package( https://dart.dev/get-dart/archive ) or the Flutter SDK (https://docs.flutter.dev/development/tools/sdk/releases) [in your case version 3.0.1) from the archive for your operating system.
Once downloaded, open your project in Android Studio and go to
In Windows
File > Settings > Languages & Frameworks > Flutter
In Mac
Preferences > Languages & Frameworks > Flutter
Change the path of Flutter SDK to the downloaded one. Or you can do the same for the Dart option in the same settings pane.
But always keep in mind that to change the Dart version which is compatible with the flutter version. So it is better to change the Flutter SDK path rather than Dart.
Once everything is done, restart the IDE.
Note: This method will only apply the changed version for the current project alone. Not even the terminal for the project won't be reflected, as the path would have been set for some other versions.
In Android studio : Go to settings => plugin => dart (update dart)
And In terminal use command : flutter upgrade
I'd use fvm to manage the flutter versions of the projects that need to be pinned to something before stable. You'll have to figure out which Dart is in each Flutter release, but that's a minor issue.

How to update Dart on VS Code?

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

How to downgrade flutter from version 2.5.3 to 1.22.6

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
