[BUG] dart run msix:create no longer works with Flutter 3.16

[jvanoeveren]

:information_source: Info

Version: v3.16.6

:speech_balloon: Description

With the release of Flutter 3.16, the build output for Windows builds have changed to include the platform architecture in the build output. https://docs.flutter.dev/release/breaking-changes/windows-build-architecture So, when I run dart run msix:create, it will run flutter build windows and output the build in build/windows/x64/runner/Release. However, I then receive an error that the build files are not found at build/Windows/runner/Release because the platform architecture hasn't been appended to the file path yet.

Interestingly enough, if I run dart run msix:create, let it build the files, and then run dart run msix:create again, then it doesn't error and packages the msix correctly. I'm assuming that's a bug as it should work first try.

Here's the full verbose logs from running the command.

@jvanoeveren Thank you so much for this important bug report 🥇

I publish new version (3.16.7) with a fix.

Hello, I ran into the same issue :

when I run dart run msix:create, it will run flutter build windows and output the build in build/windows/x64/runner/Release. However, I then receive an error that the build files are not found at build/Windows/runner/Release because the platform architecture hasn't been appended to the file path yet.

Built msix:create. running "flutter build windows"... 200.6s building msix files... /Unhandled exception: Build files not found at C:\xxxxxx/build/windows/runner/Release, first run "flutter build windows" then try again

0 Configuration.validateWindowsBuildFiles (package:msix/src/configuration.dart:258:7)

#1 Msix._buildMsixFiles (package:msix/msix.dart:107:5) #2 Msix._createMsix (package:msix/msix.dart:98:5) #3 Msix.create (package:msix/msix.dart:57:5) #4 main (file:///C:/Users/MYPC/AppData/Local/Pub/Cache/hosted/pub.dev/msix-3.7.0/bin/create.dart:4:3) But I am unable to upgrade to msix 3.16.7 due to below error: Resolving dependencies... (2.1s) Because msix >=3.16.4 depends on image ^4.0.9 and flutter_esc_pos_utils 0.1.8 depends on image ^3.1.3, msix >=3.16.4 is incompatible with flutter_esc_pos_utils 0.1.8. And because no versions of flutter_esc_pos_utils match >0.1.8 <0.2.0, msix >=3.16.4 is incompatible with flutter_esc_pos_utils ^0.1.8. And because flutter_esc_pos_network 1.0.2 depends on flutter_esc_pos_utils ^0.1.8 and no versions of flutter_esc_pos_network match >1.0.2 <2.0.0, msix >=3.16.4 is incompatible with flutter_esc_pos_network ^1.0.2. So, because XXXXXXX depends on both flutter_esc_pos_network ^1.0.2 and msix ^3.16.7, version solving failed. Basically I am stuck here and am unable to build the msix package. Could you please help me with an alternate solution how to build the msix package once the windows build command is completed. I really need help with this.
