issue when importing library into Flutter

I downloaded a Flutter app from a git repository. It's a fairly simple app that I want to experiment with.

Anyway, I upgraded my versions of Android Studio, AndroidSDK, JDK, and flutter.

I also ran 'flutter doctor' and get no issues found.

Additionally, I ran 'flutter packages get' to make sure I had everything needed.

But when I try to use 'flutter run' to run the app, I get the following error:

e: G:\Code Projects and Solutions\Flutter\NotHotDog-master\android\app\src\main\kotlin\com\bimsina\nothotdog\MainActivity.kt: (6, 27): Unresolved reference: GeneratedPluginRegistrant
e: G:\Code Projects and Solutions\Flutter\NotHotDog-master\android\app\src\main\kotlin\com\bimsina\nothotdog\MainActivity.kt: (11, 5): Unresolved reference: GeneratedPluginRegistrant

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:compileDebugKotlin'.
> Compilation error. See log for more details

When I navigate to the file with the errors, I see this:

package com.bimsina.nothotdog

import android.os.Bundle

import io.flutter.app.FlutterActivity
import io.flutter.plugins.GeneratedPluginRegistrant

class MainActivity: FlutterActivity() {
  override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    GeneratedPluginRegistrant.registerWith(this)
  }
}

I'm pretty new with Flutter, so I'm not exactly sure what to do next. I've Googled it a ton, but can't really find anything specific.

Honestly I'm not sure if this is even a Flutter issue or an issue with java.

Has anyone ever seen anything like this before?

Thanks!

The GeneratedPluginRegistrant.java file in android\app\src\main\java\io\flutter\plugins is missing, which is strange because this file should be generated automatically. I managed to find the repo and I got the same error. It seems like the project is 'broken'...

I suggest you create a new flutter project and:

  • copy dart files from /lib folder and update imports
  • copy /assets folder
  • copy dependencies and assets: part (pubspec.yaml)
  • add Firebase dependencies to Gradle files and add googleServices.json

After that it should run.
