I am having some errors with my flutter project as seen below.
I tried flutter upgrade, flutter clean, nothing is working to solve this issue.
Output from flutter pub get:

Thank you for your help.
in the pubspec.yaml you define the flutter sdk version (detailed information see here: Flutter and the pubspec file)
your importent part is the
environment:
sdk: ">=2.7.0 <3.0.0"
here you define the sdk version and like the error message says, cloud_firestore requires a SDK version between 2.16.0 and 3.0.0
so you have to adjust these version to reach the requirements

I see that in the pubspec the Dart SDK version is specified/constrained but is there anywhere to specify the Flutter SDK version? Maybe I'm missing something obvious but coming from other tech stacks like Java/Gradle I believe normally SDK versions are explicit?
What got me thinking about this is that I'm using Codemagic and have my Flutter version at "default" but I can't even tell what that is from their docs or their build logs.
You can get that from your terminal just run flutter --version, this will print out your current flutter SDK and dart SDK versions.
flutter --version
the result should be similar to this

Look like it's easy to limit it like this - I just missed it in the doc.
If I say I need ^4.0.0 then I get a meaningful error:
environment:

i'm a flutter starter and currntly adding firebase authentication to my project.
i added firebase_auth and and cloud_firestore to pubspec.yaml file using command lines
flutter pub add firebase_auth
flutter pub add cloud_firestore
dependenices are
"cupertino_icons: ^1.0.2
cloud_firestore: ^2.0.0
firebase_auth: ^1.1.3"
when trying to run my project i'm getting the error
The current Dart SDK version is 2.12.0-133.2.beta.
Because firebase_auth 1.1.3 requires SDK version >=2.12.0 <3.0.0 and no versions of firebase_auth match >1.1.3 <2.0.0, firebase_auth ^1.1.3 is forbidden.
So, because elected_ones depends on firebase_auth ^1.1.3, version solving failed.
pub get failed (1; So, because elected_ones depends on firebase_auth ^1.1.3, version solving failed.)
in the error it says the Dart SDK version is 2.12.0-133.2.beta
but when i run flutter --version i get

being trying to figure it out and i got totally lost between the '''dart pub upgrade''' and '''dart pub outdated''' through transitive dependecies
problem solved by directing the IDE to correct folder where correct sdk sits
run in terminal (in project root)
flutter doctor -v
path will be shown in the first line
Because depends on cupertino_icons >=1.0.1 which requires SDK version >=2.12.0-0 <3.0.0, version solving failed.
whenever I tried to flutter run, flutter pub get, flutter pub upgrade, I got this return in console.. I also have tried flutter update-packages it returns

How can I update Dart SDK?
you should use 1.0.0 version of cupertino in your pubspec.yaml. I think there is a problem with new version of cupertino
cupertino_icons: ^1.0.0
As of 2021-03-10 or earlier, it is no longer necessary to use cupertino_icons 1.0.0 or switch to the beta update channel (flutter channel beta). Just upgrade (flutter upgrade) and re-run flutter pub get. For details, see issue 72231.
I'm getting below message in output while running flutter pub get even though I've downgraded google map package to google_maps_flutter: ^0.5.33 which is <1.0.0.
[proj_name] flutter pub get
Running "flutter pub get" in proj_name...

Code snippet of pubspec.yaml
version: 1.0.0+1
environment:
sdk: ">=2.7.0 <3.0.0"
dependencies:
flutter:
sdk: flutter
google_maps_flutter: ^0.5.33
Result of flutter --version

Follow up the steps:
flutter channel stable
flutter upgrade
Then Try again if you get the same error then
just change in your pubspec.yaml file: from this
google_maps_flutter: ^0.5.33
to this
google_maps_flutter:
It will automatically work as it will find out the version which is compatible itself.
Try to remove the ^ in pubspec.yaml declaration
google_maps_flutter: ^0.5.33 to google_maps_flutter: '0.5.33'
If I'm not mistaken, the ^ means take this version or higher.
Update flutter version to 2.0.2 stable then clean and run app, this will solve issue
I'm getting the following error due to Dart version of my flutter setup when I run the flutter get packages command:

I would like to learn if there's some kind of command to lower dart-sdk version of the flutter framework, thanks in advance.
In the Flutter install directory execute
git checkout v"0.5.0" // for example
You can check which versions are available in the Flutter GitHub repository https://github.com/flutter/flutter
You can only change the Dart version if you change to a Flutter version that contains the desired Dart version.
Change the dependency to
dev_dependencies:
intl_translations: ^0.17.0
Add following dependency in pubspec.yaml file
version: 1.0.0+1
environment:
sdk: ">=2.0.0-dev.68.0 <3.0.0"
