Error: "Failed to create icon" on flutter pub run msix:create command

[Abhishek0116]

I tried to build my sample application as windows installable file with this package but when I ran the final command flutter pub run msix:create then an error occurred.

I am using msix: ^0.1.12

Here are full error details or output from the terminal

hello Abhishek

Maybe the problem is file path with a space,
I'm not sure yet.

Please try to setup the 3 icons in your pubspec.yaml like that:

msix_config:
  logo_path: C:\<PathToIcon>\<Logo.png>
  start_menu_icon_path: C:\<PathToIcon>\<Icon.png>
  tile_icon_path: C:\<PathToIcon>\<Icon.png>

with that the problem is still happening?

@YehudaKremer Thanks for your reply.

I tried the above solution but now another error occurred

Here's all command I ran

flutter clean && flutter pub get

flutter build windows

flutter pub run msix:create

Here's the full output

[micross]

the file path comes from the config file .packages which is uri encoded.

Hey, @micross thanks for this info.

What do I need to modify from my side? Can you please explain a bit?

[micross]

@Abhishek0116 this line msix/main/lib/src/configuration.dart

add

msixAssetsPath = Uri.decodeFull(msixAssetsPath);

after

msixAssetsPath = packages
            .firstWhere((package) => package.contains('msix:'))
            .replaceAll('msix:', '')
            .replaceAll('file:///', '') +
        'assets';

however, a simple way is to remove the space in Abhishek Kumar.

FYI: the .packages file is deprecated. see Dart Package Configuration File v2.0

@micross Thank you for your inputs!

• i update the code to use package_config.dart instead of .packages.
• added Uri.decodeFull

@Abhishek0116 please check if the problem solved in version 0.1.14

[YehudaKremer]

Hello @Abhishek0116 Did the fix help you?

[Abhishek0116]

Thanks, @micross and @YehudaKremer I have fixed my issue with your help and tested my created Windows app successfully. As @YehudaKremer said that issue is fixed in version 0.1.14 and currently I tested successfully with version 0.1.15 so I am closing this issue.
