Not working with Android SDK 28

[Vardiak]

Describe the bug
When I try to use this package with Android SDK 28, I get spammed with "web socket error" in the debug console and the socket can't connect. After multiple hours of work trying to merge my application with the example I found out that it worked by replacing compileSdkVersion and targetSdkVersion from 28 to 27 in android/app/build.gradle.

To Reproduce
Update the example to Android SDK 28

Expected behavior
The socket should connect normally.

@Vardiak is this resolved by upgrading to latest 0.2.0?

    defaultConfig {
        minSdkVersion 21
        targetSdkVersion 28

I had the same problem and I fixed it by adding the following line in the AndroidManifest.xml file inside "application":

android:usesCleartextTraffic="true"

The plugins adhara_socket_io, flutter_absolute_path, onesignal_flutter use a deprecated version of the Android embedding.
To avoid unexpected runtime failures, or future build failures, try to see if these plugins support the Android V2 embedding. Otherwise, consider removing them since a future release of Flutter will remove these deprecated APIs.
If you are plugin author, take a look at the docs for migrating the plugin to the V2 embedding: https://flutter.dev/go/android-plugin-migration.
