How do I add library module dependency to a Flutter Plugin's Android folder correctly? [closed]

Question

I'm trying to write a Flutter plugin that relies on a third-party library on Android.

The dependency has a build.gradle file, I've got the source and I can build an aar file from the command line using gradle build.

I tried to add the dependency using Android Studio but it ended up in the my_plugin/example/android directory and no matter how many times did I try to move it to the plugin's my_plugin/android directory, I always failed.

The reason why this is an issue is that even though the example app can be built and run, I cannot use the plugin in other Flutter apps (which is the whole reason one would create a Flutter plugin).

How do I need to add a local library module (source code) or the aar (that I can build any time) to the Flutter plugin's Android implementation?

Answer 1

well, you were halfway through the process...

1. Go to File -> New module -> Select JAR/AAR, locate the JAR/AAR you want to add, decline creating a gradle wrapper and this will create a folder with your file and a build.gradle file. Copy the library folder name for usage in the next steps.
2. Move the newly created folder to the android folder.
3. Open settings.gradle in android folder and to the beginning of the file add this line:
   • include ':android/library_folder_name'
4. Open build.gradle in android folder and in the dependencies block add this line:
   • implementation fileTree(dir: 'library_folder_name', include: ['*.aar', '*.jar'], exclude: [])
