[Bug]: No implementation found for method getAll on channel dev.fluttercommunity.plus/package_info

[CodeDoctorDE]

Platform

Linux (Fedora 36)

Plugin

package_info_plus

Version

3.0.0

Flutter SDK

3.3.4

Steps to reproduce

1. Upgrade to the latest package_info_plus 3.0.0
2. Use await PackageInfo.fromPlatform()

After downgrading to 2.0.0, everything works.

I cloned the example from the main branch and everything works there.

Code Sample

Future<bool> hasNewerVersion() async {
    final packageInfo = await PackageInfo.fromPlatform();
    return packageInfo.version != kVersion;
}
const kVersion = "1.0.0";

I have the same problem.

Platform
Linux (Linux Mint 20.2)

Plugin
package_info_plus

Version
3.0.0

Flutter SDK
3.3.4

[miquelbeltran]

I cannot reproduce the error.

Steps:

1. Create new project with flutter create error_1270
2. Add plugin with flutter pub add package_info_plus

  package_info_plus: ^3.0.0

4. Add call to PackageInfo.fromPlatform()

    final packageInfo = await PackageInfo.fromPlatform();
    print(packageInfo.appName);

5. Run project on Linux.
6. Log appears correctly:

flutter: error_1270

[san-smith]

I am also got a similar error with device_info_plus:

UnimplementedError (UnimplementedError: linuxInfo() has not been implemented.)

Platform
Linux (Linux Mint 20.2)

Plugin
device_info_plus

Version
7.0.0

Flutter SDK
3.3.4

@CodeDoctorDE @san-smith can you please share the whole file where it crashes, or at least the imports? Thanks!

[miquelbeltran]

Can you confirm that you have done a proper flutter clean and pub upgrade?

[CodeDoctorDE]

I did.
I ran the example in the repo and it works. Only on my project it happens

[CodeDoctorDE]

on my package_info_plus folder there is no linux folder

[nohli]

@CodeDoctorDE
Can you please try flutter clean and flutter pub upgrade?
And I meant the imports in the Dart-file where the failing method is called. Please share as well 🙂

[CodeDoctorDE]

i did it already.
This is the line: https://github.com/LinwoodCloud/Butterfly/blob/a3f3fa5142d1040b189f2e07ac2096d4a48799ec/app/lib/cubits/settings.dart#L424
Why does the error happen if there is no method call on linux?

[miquelbeltran]

The Linux implementation of the plugin is in the src/package_info_plus_linux.dart file.

The pubspec.yml is configured to use this class as the Linux implementation:

        dartPluginClass: PackageInfoPlusLinuxPlugin

For some reason, it seems that something is not being generated correctly for some users, and so Flutter/Dart is not linking to the correct implementation class.

I see that on this branch, the package_info_plus is still at v2.0.0

Do you have an up-to-date branch of the project using 3.0.0?

[CodeDoctorDE]

I pushed the update-dependency branch a few seconds ago.
The problem only happens on runtime, I will try out the build artifacts.

I wanted to test it on my machine before pushing the upgrade.

I will check your code if you don't mind. Can you specify the step by step to run the app and reproduce the issue? Currently trying to run your app but it fails as it tries to write to /usr/local/butterfly which I prefer no to :)
