Unhandled Exception: MissingPluginException

[McCrafterIV]

I got the following error while using the plugin:

I've used the same code as it is in the example:

UpdateApp.updateApp(url: filePath, appleId:"375380948",title:"Title",description:"Description");

I get the filePath from the FilePicker dependency and also checked the path. How do I resolve this issue? At this point, the plugin isn't usable at all because it crashes instantly.

Hello, please provide flutter doctor -v, I will take a look, thank you

[McCrafterIV]

Of course

I'm very sorry, but I'm in a hurry for things that I'm busy working on lately. I may have to make changes later.

[McCrafterIV]

Ok, what does later mean? I mean, do I have to wait only a week or a month or so? If it would take to long I need to use an other dependency.. :/

[mofada]

My God, I have the same problem, I will update and publish it as soon as possible

[mofada]

You can use it first, I will test the ios part today and then post it, good night.

dependencies:
  #  update_app: ^0.1.3
  update_app:
    git:
      url: https://github.com/mofada/flutter_update_app.git

[McCrafterIV]

I've tested it. No error is thrown but also nothing is happening at all. After the APK file was selected I try to update using the following syntax:

await UpdateApp.updateApp(url: filePath, appleId:"375380948",title:"Title",description:"Description");

but it doesn't work. Flutter doctor also doesn't output something suspicious.

[mofada]

I use DownloadManager to download, you look at your notification bar, is there a download progress

[McCrafterIV]

My bad,
I thought I have to provide a local path. After changing the path to a download URL it now works perfectly fine
Thanks for the help, I'll close this now

[mofada]

The plugin has been updated

dependencies:
  update_app: ^0.1.5
