I update my flutter to latest version.

When I do a get package update, I get an error:
Package doesn't exist (the pubspec for google_maps_flutter 0.5.6 from git has version 0.5.13).
But when i update from version 0.536 to 0.5.13 and then do a package update, it show nothing.
Maybe pubspec.lock is forcing to use that version.
Try these steps:
Delete pubspec.lock file.
After that run 'Flutter clean'
Then run 'Flutter pub get'
Then run the app.
Hope it will work for you.
The last version of this package is the 0.5.19+2.
google_maps_flutter: ^0.5.19+2
Follow this instruction and it should work.

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 trying to upgrade Flutter version in my project from 2.8.0 to 3.7.0. If I got it right flutter should be using the default version installed on my machine, but it doesn't. See commands below.
flutter --version

Still it tries to use previous version
flutter pub get

Because xxx depends on flutter >=3.0.0 which doesn't match any versions, version solving failed.

you could try :
flutter clean
flutter pub get
if it repeats, maybe you could:
flutter clean
flutter pub upgrade
I run flutter upgrade and and I got the following message

but when I try to upgrade the packages including the riverpod which has got to the stable release today
I got the following message
The current Dart SDK version is 2.13.4.
Because simple depends on flutter_riverpod >=1.0.0 which requires SDK version >=2.14.0 <3.0.0, version solving failed.
pub get failed (1; Because simple depends on flutter_riverpod >=1.0.0 which requires SDK version >=2.14.0 <3.0.0, version solving failed.)
I when check the dart sdk in the setting of the editor I'm currently using, the dart sdk is of version 2.13.4
anyone know how to fix this issue ??
Try removing the versions, keep only the dependency names in pubspec.yaml . Then run flutter pub get. It will automatically download all compatible versions.
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 run flutter upgrade it works correctly but then i got errors with if used with widget
error: This requires the 'control-flow-collections' experiment to be enabled
this is my flutter version after update
i run flutter --version and this was the result

i need some help thank you
update your pubspec.yaml
sdk: ">=2.7.0 <3.0.0"
2.Create a file at your project root named analysis_options.yaml
3.Paste this into the newly created file
analyzer:
enable-experiment:
- spread-collections
4.Just save all and restart your editor then open terminal at your project directory and type 'flutter pub get`
