Problem running on iOS

[SaxPlayer]

I copied the example app including all the supplied assets with a view to trying this out before developing my own app however the example won't run at all and throws the following error:

Launching lib/main.dart on Dalziel in debug mode...
Developer identity ****************** selected for iOS code signing

Error launching application on Dalziel.

Code is exactly as it is in the example folder, no changes made.

The example and package works fine, please consider updating your Flutter SDK (version>=3.27.1) or just use version v2.0.3 of the package, thanks for reporting I will update min sdk version of the package.

[SaxPlayer]

Thanks for the advice. Updated the min SDK in pubspec.yaml and ran flutter upgrade. Now see the following error:

The current Dart SDK version is 3.6.2.

Because example requires SDK version >=3.27.1 <4.0.0, version solving failed.
Failed to update packages.

@SaxPlayer you should upgrade flutter too. Only modifying the sdk version in the pubspec is not sufficient. your local flutter is still an old version. Try to use fvm to manage different flutter versions.

@SaxPlayer you don't need to change the min sdk in package yaml, just upgrade your flutter SDK to lates version
