Hi @A7MeDG0L0L,

I added those files to be able to build app on macos, I have no exeprience in making a flutter package for macos so i trimmed files found in just audio package to trick pod ; hence the AssetsAudioPlayer reference in .swift file

This works on my mac, What error do you get if you try to build macos version of blue_thermal_printer/example ?

Hi @flutter-painter as I mention above that I get when build example I tried again and got same error

@flutter-painter Can you tell me which files you tirmmed from JustAudio package and where you put these files into that package ?

[flutter-painter]

Hi @A7MeDG0L0L

The three classes are here : macos/

I also reworked a typo in the podspec macos/blue_thermal_printer.podspec

[A7MeDG0L0L]

@flutter-painter Can you create a new fork with your changes to use it because I didn't understand which files from JustAudio/macos Or JustAudio/example/macos Thanks in advance

[flutter-painter]

You should not need to add anyhting else, I was just providing context to the peculiar look of the /macos folder in this package.

It works without any edits from the latest version of blue_thermal_printer I am sure you tried to run : flutter clean

But did you also remove all versions of blue_thermal_printer from your .pub-cache ? It should be here : flutter/.pub-cache/hosted/

[A7MeDG0L0L]

@flutter-painter Currently I cloned this repo and run example but can you explain to me what you did with these three classes (Removed / Copied from another source / edited)

[flutter-painter]

You are right I think I changed locally in BlueThermalPrinterPlugin.m

SwiftBlueThermalPrinterPlugin -> BlueThermalPrinterPlugin

I have issues building at the moment so I cannot test and PR, but it should fix it for you

By Changing that it failed to build.

Hi @A7MeDG0L0L,

Thank you for trying it out and sorry for the trouble, I messed around with the macos files again and straightened it out. PR submitted here :

https://github.com/kakzaki/blue_thermal_printer/pull/169

• remove the swift file

• update the content of the .m with

#import "BlueThermalPrinterPlugin.h"

static NSString *const CHANNEL_NAME = @"plugins.kzaki.com/blue_thermal_printer";

@implementation BlueThermalPrinterPlugin
+ (void)registerWithRegistrar:(NSObject<FlutterPluginRegistrar>*)registrar {
    FlutterMethodChannel* channel = [FlutterMethodChannel
                                     methodChannelWithName:CHANNEL_NAME
                                     binaryMessenger:[registrar messenger]];
    BlueThermalPrinterPlugin* instance = [[BlueThermalPrinterPlugin alloc] init];
    [registrar addMethodCallDelegate:instance channel:channel];
}

@end

// note reformatting this to ease copy paste @kakzaki if you could generate a new version of blue_thermal_printer (^1.2.4) it would be much appreciated
