Codemagic iOS build issue

Question

I am trying to compile my app with Codemagic for iOS . Locally, my environment is:

[√] Flutter (Channel stable, v1.9.1+hotfix.6, on Microsoft Windows [Version 10.0.18363.657], locale en-US)

[√] Android toolchain - develop for Android devices (Android SDK version 28.0.3)

[√] Android Studio (version 3.5)

I have no issue to compile to Android app. However, when I switch to Codemagic , and I setup my config to:

Flutter 1.9.1+hotfix.6
Xcode 11.1

I have the following error reported:

Compiler message:
lib/app/ui/widgets/color_theme_picker_widget.dart:2:8: Error: Error when reading '../programs/flutter/.pub-cache/hosted/pub.dartlang.org/flutter_colorpicker-0.3.2/lib/block_picker.dart': No such file or directory

 - 'ColorThemePicker' is from 'package:biorhythms/app/ui/widgets/color_theme_picker_widget.dart' ('lib/app/ui/widgets/color_theme_picker_widget.dart').
Try correcting the name to the name of an existing method, or defining a method named 'BlockPicker'.

I would appreciate any feedback, Thanks!

Answer 1

In case someone came across a similar issue - in my case, it was caused by the following line in my pubspec.yaml file - flutter_colorpicker: any , since it loads the most recent flutter_colorpicker version, where the above file has been removed. SO basically, I had to adjust the code to the most recent version. Also as a general thumb rule - just set your plugin / package version to a specific one eg flutter_colorpicker: ^0.3.2 .
