Seems that the issue was introduced recently in 2.0.0. In the meanwhile please use 1.0.0 I will take a look at this.

[miquelbeltran]

I can't reproduce the issue with the example project shipped in the plugin, running it for Android.

Can you provide the build.gradle files of your project?

The Android build.gradle files probably need an upgrade, check the ones in the example project, like here: https://github.com/fluttercommunity/plus_plugins/blob/main/packages/connectivity_plus/connectivity_plus/example/android/build.gradle#L8 and here: https://github.com/fluttercommunity/plus_plugins/blob/main/packages/connectivity_plus/connectivity_plus/example/android/app/build.gradle

Try to upgrade the com.android.tools.build:gradle and the compileSdkVersion

also paging @juliansteenbakker who worked on those changes recently

[juliansteenbakker]

This is already fixed in #521 and released in v2.0.2

I can confirm, creating a new flutter project and adding connectivity_plus to it and the project compiles for Android.
