CodeMagic.yaml Flutter Version Ignored in favor of Workflow Editor Flutter version

[wolfe719]

If you are looking for help, please confirm the following...

• I confirm I have searched the Docs, Codemagic Sample Projects, and GitHub Discussions.
• I confirm the software versions on my local computer match the ones in CI environment (e.g. Xcode version, Gradle version). See here
• I confirm I am able to do a fresh clone of the repository and build the project on my local computer.

Which mobile framework are you using?

Flutter (Dart)

Steps to reproduce

1. Create a flutter project
2. Create a CodeMagic app with workflow editor that specifies explicit versions of Flutter / Xcode / Cocoapods
3. Make sure that CodeMagic builds the application correctly
4. Create a codemagic.yaml file that specifies a different version of Flutter and Xcode
5. Alter the pubspec.yaml to explicitly fully specify the Dart SDK of the YAML file's version of Flutter
6. On the web interface, switch from using Workflow Editor to using YAML file
7. Kick off a build of a branch that has the new codemagic YAML file

Expected results

Watch the build use the codemagic.yaml file specified Flutter / Xcode / Cocoapods versions

Actual results

See the build fail because of a mismatch of Dart version specified in the pubspec.yaml and the Dart version from the formerly-specified-through-the-CodeMagic-Workflow-Editor Flutter version.

The codemagic.yaml flutter version is not used.

Instead, the Flutter version that has been specified in the CodeMagic Workflow Editor is used.

NOTE: In the build ID case listed below, the codemagic.yaml file calls out a Flutter version 3.24.4. The CodeMagic Workflow Editor (if I switched back to it), shows a Flutter version 3.24.3, and my pubspec.yaml calls out the specific Dart SDK 3.5.4 (belonging to Flutter version 3.24.4)

Hey @wolfe719.
From the logs of the build ID, the flutter version 3.24.3 is being used. The reason for the build failure was also explained in the failed step:

Resolving dependencies...
The current Dart SDK version is 3.5.3.

Because device_flutter requires SDK version 3.5.4, version solving failed.


You can try the following suggestion to make the pubspec resolve:
* Try using the Flutter SDK version: 3.24.5. 

It's attempting to run the flutter packages pub get command with Dart version 3.5.3 but because version 3.5.4 was explicitly stated in your pubspec.yaml file, hence the failure. You can use a range in your pubspec.yaml file instead e.g:

environment:
  sdk: ">=3.2.6 <4.0.0"

and the correct version 3.5.3 will be used.
Please let me know if you have any further queries.
