Hi @chyiiiiiiiiiiii, thanks for choosing Amplitude.

The error message you're encountering suggests that the Dart library 'dart:js' is being used in your Flutter project, but it's not available on the iOS platform. This is because 'dart:js' is a library intended for web development and is not supported in Flutter applications that target iOS or Android. To resolve this issue, you'll need to identify where 'dart:js' is being used in your project.

I confirm that Amplitude Flutter SDK is not using 'dart:js" and I can run the example project on my local.

I would suggest to check if it's using elsewhere in your project. Hope this helps.

FYI, I had the same issue until I realized that VSCode automatically imported the JS version of the library when I added the init function. Just in case others see the same issue.
